The VERO-S NSL turn clamping station from SCHUNK, the competence leader for clamping technology and gripping systems is a real productivity booster for milling/turning centers. It is based on the highly efficient VERO-S quick-change pallet system, and transfers the effect of the rapid workpiece change onto the lathe machining. By means of the patented double angled stroke, and the integrated turbo function, the NSL turn achieves pull-down forces of up to 125 kN, and holding forces of up to 375 kN. Therefore the clamping station from the innovative family-owned company ensures an extremely rigid and reliable clamping of devices and workpieces. A centering taper ensures a runout accuracy of less than 0.01 mm. Locking of the three or five integrated clamping modules is done via two clamping slides. It is self-locking and uses form-fit clamping. During machining the clamping station is unpressurized. Integrated springs provide for a permanent and secure clamping. For opening the locking, a pneumatic system pressure of 6 bar is sufficient.
Completely sealed

In order to increase the product life and process reliability, all functional parts such as base body, clamping pin, and clamping slide are made of hardened stainless steel. The maintenance-free modules are completely sealed and are reliably protected against chips, dust and coolant. A display shows the current clamping condition, and thus avoids errors before clamping. An intelligent plumbing of the module leaves enough space for bore holes on the base plate. Therefore the NSL clamping station can be used on all conventional machine types, and is suitable for speeds of up to 2.000 rpm. In size 450 three clamping modules are available for manual chucks of size 315. Size 570 offers more than five clamping modules for manual chucks up to size 630 mm.

Switching systems is getting easier all the time

The start-up and integration of mechatronic modules has become much simpler due to factors such as adaptive drives. However, users continue to require significantly greater know-how for mechatronic solutions than for pneumatic ones. While intuitive plug & work concepts will at some point become available for complex systems and high-speed applications, this is not yet the case. However, the compatibility and handling of simple mechatronic applications has improved significantly in recent years. Within its mechatronic series, SCHUNK has developed a group of modules that have made the switch from pneumatic to mechatronic systems easier than ever before. For example, the EGP gripper for small components is comparatively simple to control via a digital sensor distributor. In many cases, users can transfer the sensor systems used in the MPG plus to the EGP, and easily convert existing systems from pneumatic to electrical operation. Similar to its pneumatic counterpart, the EGP can be screwed through and fixed either laterally or at the base, which also simplifies the conversion to a mechatronic solution.
With these rapid advances in mechatronic modules, users and system planners can benefit from a careful assessment of the advantages and disadvantages of different types of drives. SCHUNK offers both pneumatic and mechatronic solutions within what is the world's most comprehensive module selection for gripping systems, which in turn provides users with significant synergy benefits.

In many industries, the increasingly wide range of product variants, the ever-shorter cycle of innovation, and the increasing comparability among products are leading to an enormous pressure on costs. Experts believe that production automation will be one of the keys to business success in the coming years. These issues also apply to gripping systems: the precision, flexibility, speed and reliability of a gripping system has a significant impact on the profit margin which they can achieve. Although pneumatic gripping systems were long considered the state of the art, mechatronic solutions have since made significant strides. As a result, users and system planners are increasingly faced with the question of which drive concept is more advantageous to handling and assembly processes: pneumatics or mechatronics?
Adaptable drives, versatile controller concepts, and the large selection of standard interfaces have made it increasingly easy to integrate mechatronic modules into higher-level system controllers. At the same time, the rapid progress in electrical servo drives are making mechatronic components increasingly attractive from a price and efficiency perspective. As a result, comparing the advantages of the two drive concepts has become an increasingly important step in the process of selecting the optimal gripping system.

Pneumatic solutions are robust, have a compact performance, and are easy to operate.

Pneumatic gripping systems have been continuously optimized over the past decades. They are generally fully developed from both a construction and mechanical point of view. Systems such as the multi-tooth guided PGN plus universal gripper, the MPG plus is a roller guided gripper for handling small components, and the most powerful SRU plus swivel unit from SCHUNK, the compentence leader for clamping technology and gripping systems, are powerful, robust and reliable performers for even the most demanding tasks. Pneumatic systems are very easy to operate and maintain, making them well-suited to users who do not have a high level of technical knowledge. Finely graduated, standardized series and a comprehensive range of accessories make it possible to achieve a customized design at an attractive price. On average, pneumatic modules require an investment that is one-third to one-half that of comparable mechatronic modules. Users who assemble only identical parts, who require high cycle times, and who have little mechatronic knowledge are thus well-served by pneumatic solutions. As a rule, only the sealing components of these systems require ongoing maintenance, which also helps users maintain an overview in their maintenance costs. Because of the need for compressed air, their operating costs are comparatively high; however, this can be significantly reduced by the use of micro valves. Nowadays, highly efficient valve solutions are available for many pneumatic modules, from grippers to complete pneumatic pick&place units; these solutions can reduce compressed air consumption by up to 90% while also increasing the cycle time by up to 100%. By these means, pneumatic pick&place units can achieve up to 95 picks per minute with a repeat accuracy of 0.01 mm and high energy efficiency. However, air-operated rotary and linear modules are still poorly suited to particularly large translational movements over approximately 1500 mm, or to high loads over approximately 50 kg. Pneumatic systems remain poorly suited to such conditions. By contrast, electrically driven linear modules (spindle/belt drives) can achieve linear movements up to 8000 mm, and electrical rotary modules can handle loads up to 800 kg.
Mechatronic solutions are energy-efficient and versatile in their application

Applications that require versatile and adjustable handling are well-suited to the use of electrically driven modules. They offer particularly high versatility: they allow mechatronic grippers, rotary and linear modules to approach non-standardized sequences of intermediate positions with a high level of precision and dynamics. During these processes, the position, stroke, speed, acceleration, force, and torque can all be individually adjusted. This makes it possible to handle a variety of parts during a process. In addition, mechatronic systems can quickly be adapted to handle new part designs. This increases the versatility of handling and assembly processes, and also provides a great deal of flexibility in the introduction of new products, sizes, and equipment specifications. The increasing wide range of product variants also make these systems increasingly attractive. This is particularly the case for applications with a high number of cycles and many gripping processes. In such processes, electrically driven grippers operate with greater energy and cost efficiency than their pneumatic counterparts. Even though the initial investment is usually significantly higher than in pneumatic modules, decreases in the cost of acquisition and operation have led to significant decreases in the amortization time of mechatronic modules. Their performance is now also on a par with pneumatic solutions. Like its pneumatic counterpart, for example, SCHUNK's mechatronic EPG gripper for small components is now equipped with a high-performance junction roller guide, which offers unusually high efficiency and speed while maintaining consistently high gripping force. Even very simple mechatronic modules are equipped with maintenance-free servo motors, which help make the modules extremely compact and reliable. In some cases, mechatronic modules can even be started up or maintained via the internet or a data line.

Complete News:
Mechatronic gripping modules offer numerous possibilities for users and design engineers. The competence leader for clamping technology and gripping systems SCHUNK is now going one step further: The innovative family-owned company is the very first manufacturer to bundle numerous mechatronic modules in a single modular system. The spectrum extends from simple grippers as an alternative to pneumatic grippers to versions with integrated intelligence and adaptable, mechanical grippers that can be equipped with a broad range of motors and functions.
Electrically driven gripper as an alternative to pneumatics

The electrically driven small parts gripper EGP proves that mechatronic modules by no means have to be complicated. With respect to the mechatronics it focuses on the essential and places hardly any demands on the user. For example, it is very easily controlled by the sensor distributor. It also allows conversion from pneumatic to electric gripper modules in a flash. An added advantage is that the sensor system of the time-tested pneumatic small parts gripper MPG-plus can be transferred 1:1 to the EGP.

Compared with other electrically driven small parts grippers on the market, the gripper scores points with respect to its high speed and simultaneous high gripping force. Its powerful cross roller guide ensures high efficiency and makes the gripper a dynamic and high-performance specialist for demanding Pick&Place applications. Since excess material is saved on the gripper housing and internal components made of special high-performance aluminum reduce the weight, this enhances the dynamics and energy efficiency of the higher level system.
Intelligent grippers shorten processes

The second pillar of the mechatronic modular system from SCHUNK is the intelligent mechatronic gripper. These grippers allow optimization of production, assembly and handling processes and even implementation of completely new solution strategies. That this is possible without extensive specialized knowledge of electronics and control technology is demonstrated by the WSG 50. Easy commissioning is already built into this 2-finger parallel gripper. In addition to Profibus DP, CAN and RS232 it also has an Ethernet TCP/IP interface, which due to the integrated web server allows fast and easy commissioning using a standard web browser. No additional software is necessary. An electronic sensor interface is integrated in the base jaws of the gripper, which makes it possible to incorporate diverse sensors in the gripping process.

The highlight of the gripper is the intelligent detection of gripped parts. In combination with the high positioning accuracy of the gripper, this allows the WSG 50 to execute a gripping command with optimized cycle times. This significantly reduces the load on the higher level process controller, because the gripper itself features intelligent functions for independent execution of sub-routines. Depending on the respective application, the functionality of the WSG 50 can be individually adapted by means of the built-in, easy-to-learn script language. Once the scripts have been created, they are simply saved on the built-in SD card. This option of individual programming lets users solve difficult tasks reliably and with relative ease.

Adaptable gripping modules

The third and final pillar consists of mechatronic gripping systems with adaptable electric drives. Depending on the handling system and the desired functions, these modules can be equipped with a broad range of servo motors. It is possible, for example, to control the module with the same commands used for the higher level robot. Every gripping position can be changed easily and flexibly with no problems due to incompatible control signals. In addition, the characteristics of the system controller with respect to programming, safety or field buses can be used directly. The most recent example for such an adaptable gripper is the robust long-stroke gripper EGA. All standard industrial servo motors can be used to drive the gripper, in particular also servo motors with a voltage range starting at 230V AC. Depending on the application the motor can be flange mounted parallel to the direction of motion, which is especially favorable for robot applications in which the height of the gripper needs to be minimized. Alternatively, it can be mounted at a right angle to the direction of motion, to minimize the width of the gripper for gantry applications, for example. The EGA has an extremely flat and compact design and minimal interfering contours. Due to the anti-friction guideway, the EGA is permanently precise and very long-lasting. The weight-optimized design of the gripper and the dynamics and energy efficiency further enhance the system.
In the opinion of Matthias Poguntke, Business Unit Manager for Product- and Portfolio Management at SCHUNK, both pneumatic and electric drives will be viable alternatives in the future. "Mechatronic modules are especially flexible and very attractive in economic terms, despite the higher initial investment," Poguntke explains. "Arguments for pneumatic grippers are the attractive price, the robust construction and the user-friendly commissioning and maintenance." He therefore recommends comparing the application, environment and individual requirements to determine which drive type is more cost effective.

The hydraulically actuated, self-centering precision steady rests ZENTRICO THL plus from SCHUNK, the competence leader for clamping technology and gripping systems are equipped with a standard full equipment, and therefore are precisely tailored to the increasing precision requirements of turning operations. Due to the optimized lever kinematics, central lubrication, integrated roller rinsing, and dirt guard, they achieve maximum clamping forces per roller and maximum centering and repeat accuracies of up to 0.01 mm.
During the development of the durable, robust, and high-precision steady rests, the lathe chuck’s experts of the innovative family-owned company have attached great importance on practical aspects and versatility. A universal connection ensures that all current steady rest carriers can be used. They are available in a stationary and in a cylindrical version.

Slim and versatile

An oval piston cylinder provides for the ZENTRICO THL plus’s slim design, which takes up less space. For narrow clearances, a special design is offered where the clamping cylinders are laterally attached. The standard hydraulic connections are laterally attached to the cylinder, or are rear-mounted. Moreover, the roller rinsing belongs to the standard equipment and protects the steady rest against abrasion marks during machining operation. On request, the rollers of the steady rests can be equipped with an eccentric fine adjustment. Since SCHUNK always keeps automated manufacturing in mind, the arms of the steady rest have been designed correspondingly: On option, a swivel arm provides for the necessary free space for automated loading from above. In addition, they can be equipped with a stroke monitoring system. The ZENTRICO THL plus is available in 13 sizes for a clamping range between 4 and 460 mm.

Complete News:
The Powerball concept from SCHUNK, the competence leader for clamping technology and gripping systems, takes another step forward: With the Powerball-Lightweightarm LWA 4, the pioneer of modular robotics presents an especially compact and flexible aid for stationary and mobile applications in service robotics and industrial handling. The powerful lightweight module from the innovative family-owned company features a weight/payload ratio of 2:1 and is one of the most high-power lightweight arms in the world. At a dead weight of 12 kg, it can dynamically handle loads of up to 6 kg, and has a gripping radius of more than 700 mm. Due to the compact design of the front end, or wrist joint, the arm can be easily maneuvered in close spaces. Its excellent repeat accuracy of 0.06 mm provides for high process stability for demanding measuring and testing tasks. Also, the intelligent design prevents dangerous crushing and shearing movements, making it safe to use around people as well.
Central elements of the lightweight arm are three compact ERB Powerball modules, which combine the movements of two axes. The entire electronic control and regulation circuitry is integrated in the joint drives. Position, speed, and torque can be flexibly regulated. An innovative quick-change system with integrated signal feed-through allows for fast and easy commissioning of the Plug & Performance gripping system. Since the supply lines for gripper and tools are completely within the module, there are no interfering cables on the peripheral devices. Due to the integrated intelligence, universal communication interfaces and cable technology for data transfer and power supply, the arm can be quickly and easily integrated in existing control concepts. The manipulator is supplemented by an industrial robot controller with an integrated CoDeSys PLC. Teaching and instruction is made easy by means of a hand-held control panel with a touch-screen display.
24 V DC supply voltage enables mobile use as well as use at changing locations. Consistent lightweight construction and the state-of-the-art torque motors keep the energy demands of the lightweight arm down to an average of 80 W. That lowers energy costs, provides for longer work periods when using rechargeable batteries, and also allows the use of small-format batteries.

Complete News:
If machine tools are loaded automatically, a reliable, precise, and space saving workpiece change is playing an important role. For this particular case, SCHUNK, the competence leader for clamping technology and gripping systems has developed a slim, light-weight coupling with minimized interfering contours, where the pallet loading is taking place very close to the machine table. By using the VERO-S NSR, very thin attachments to the clamping station and pallet are feasible, and therefore a lot of space remains for the workpiece in the machine room, and for the axes motions.
A lightweight handles up to 350 kg

At a weight of 1.6 kg (size 160), the robot coupling achieves pull-down forces of up to 15 kN, and is an extremely rigid system. It transfers torques of up to 1600 Nm, and is also suitable for reliable handling of heavy pallets of up 350 kg (with dimensions of 400 x 400 mm). Every quick-change pallet system of the family-owned company is equipped with a double angle clamping stroke, and therefore allows such high weights. In order to achieve an optimal relationship between rigidity, robustness, and weight, the SCHUNK engineers have designed every part that does not transmit force in aluminum, and parts that do transmit force in hardened stainless steel. The module’s locking is self-locking and uses form-fit clamping. At a pneumatic system pressure of 6 bar the module can be unlocked, without needing lubrified air. Opening, closing, and pallet presence are monitored via inductive proximity switches, and therefore the whole changing process can be monitored, too. Moreover, the module with a high compact performance is completely sealed and thus protected against chips and coolant.

With the WSG 50 from SCHUNK, the competence leader for clamping technology and gripping systems belongs to a new generation of mechatronic high-tech grippers. Beside Profibus DP, CAN and RS232, the WSG 50 for the first time disposes of an ethernet TCP/IP interface. Via a typical web browser, the WSG 50 can be commissioned quickly and easily, without the installation of a new software.
Due to the integrated "gripped component detection" and the high positioning accuracy, the WSG 50 is for the first time able to carry out a gripping command in a shorter cycle time, and the superior process control is significantly relieved. The WSG 50 is a universal genius. For particularly difficult cases, the range of functions of the installed and easy to learn script language can be individually adjusted by the customer himself. The contained scripts are filed on the built-in SD card.
The WSG 50 is the first gripper which disposes of an electric sensor interface in the base jaws. This is the basis for a direct integration of different sensor systems in gripping pro- cesses. Thus it is an ideal helper for sophisticated automation solutions, where a high flexibility or sensitivity of the gripping process is required. With the optional WSG-FMF force-measuring finger, forces which occur during the gripping process can be precisely recognized and controlled. The WSG 50 provides a stroke of 110 mm and a variable gripping force from 5 to120 N. Now in stock.

Operation with a vacuum unit has advantages

In machining, in order to produce underpressure, two methods are used. Low-cost Venturi nozzles can be directly integrated into the matrix plates. They are compact, light, low-wear, develop no heat and make it possible to quickly generate a vacuum. However, they have a limited suction capacity, which means only completely sealed and relatively small surfaces can be clamped. Suctioned liquids can only be disposed of with difficulty with Venturi nozzles. In addition, the nozzles create a consistantly loud noise. Users who require a lot of flexibility and reliability usually decide for low-maintenance vacuum units, which are low-vibration and quiet-running and can be used with one or several matrix plates. High underpressures at simultaneously high volumetric flows can be produced with them. Vacuum units with an integrated reservoir provide a strong suction impulse and prevent a sudden drop-off of the vacuum. Ideally the units have various components for monitoring the system, and interfaces for integration in the machine control system. With special emergency stop functions, the vacuum pump is protected from being damaged by suctioned liquids, or stops the machine if there is sudden loss of clamping force.

In comparison to clamping brackets, clamping blocks, jaw chucks, quick-change pallet systems, or magnetic clamping technology, vacuum clamping technology is mostly unknown in the metal cutting industry. Nevertheless, vacuum clamping technology can perform a valuable service here, especially when machining thin parts that are susceptible to deformation, or workpieces made of aluminum and other non-ferromagnetic materials. Particularly when they are in the form of versatile matrix plates, they are a useful and easy to handle addition to clamping devices already in use.
First a few basics on how vacuum clamping systems function. A vacuum occurs, according to DIN 28400, when the particle number density of a gas is lower than the particle number density of the atmosphere at the earth's surface, or, in other words, when the pressure of a gas is lower than the atmospheric pressure. It is precisely the pressure difference between the evacuated space below a workpiece and the natural atmospheric pressure above a workpiece that a vacuum clamping system uses to clamp workpieces. In contrast to the widely held belief that a workpiece is subject to suction when it is vacuum clamped, in fact the clamping force is created because the natural air pressure presses the workpiece evenly over its entire surface onto the clamping plate.

As a rule in the area of vacuum clamping technology, vacuum values are given in terms of the difference between ambient pressure and underpressure, and the ambient pressure is used as a reference point and is assumed to be 0 bar. Vacuum values also always have a minus sign in front of them, e.g. -0.3 bar (1 bar is equal to the force of 10 N on a 1 cm² surface). In order to determine the holding force (F) for a vacuum clamping system, the pressure difference (p) is multiplied by the effective surface (A). If for a 160 mm x 160 mm workpiece, a surface area of 150 mm x 150 mm is evacuated to -0.6 bar, the holding force (suction force) in the z-direction is F = 6 N/cm2 x 15 cm x 15 cm = 1350 N. Holding force and underpressure behave proportionally to one another. In contrast, the evacuation time as well as the energy required increase disproportionally if the underpressure and the holding force along with it are increased. In the above example, if the underpressure is increased by 1.5 times to -0.9 bar, the holding force increases proportionally to 2025 N. The energy required and the evacuation time increase disproportionally by a factor of 3.

A sophisticated solution for workpiece clamping in the area of machining is the modular vacuum clamping system PLANOS from SCHUNK, whose vacuum unit has all of these safety features. Beyond that, the oil-lubricated vacuum pumps are equipped with a liquid separator, which also serves as a vacuum reservoir. A vacuum operation center makes it possible to automatically empty the unit during running operations if necessary, without interrupting the process. Since the vacuum pump is only activated when the vacuum falls below 85 %, the units are especially energy efficient and quiet. If necessary the control unit can be deactivated, so that the pump can be run in continuous operation mode. PLANOS matrix plates come in the following sizes, 300 x 200, 300 x 400 and 400 x 600 mm with grid dimensions of 12.5, 25 and 30 mm. Workpieces with a height tolerance of +/- 0.02 mm can be clamped on them. On request, the matrix plates from the competence leader for clamping technology and gripping systems can be equipped with patented friction islands. These are automatically activated via the vacuum supply and allow higher shearing forces. In comparison with matrix plates without friction islands, the horizontal holding forces increase by up to 30 % with friction islands. At the same time, this puts no additional force on the workpiece. The friction islands are oil and ozone-resistant and can be replaced individually if necessary. Matrix plates from by the innovative family-run company are often used as an additional clamping solution. As part of the worldwide largest modular program for stationary workpeice clamping, they can be mounted quickly and easily on already existing clamping devices, on MAGNOS magnetic clamping plates, for example, or on the VERO-S quick change pallet system.

Clamping of thin parts without risk of deformation

In the area of metal products cutting, vacuum clamping systems in the form of matrix plates whose base body consists of high-strength aluminum have proven to be optimal. They can be produced with standardized dimensions and grid dimensions of differing degrees of fineness. The clamping surface can be enlarged by connecting several matrix plates together. Based on the workpiece geometry, the machining and the horizontal forces, the suction surface and the necessary grid dimensions can be determined. The more fine the grid, the more complex the geometry of the workpieces can be.
In order to clamp a workpiece, a caulking strip that corresponds to the workpiece geometry is placed in the grid. Variable-use mechanical backstops make positioning easier and prevent the workpiece from shifting horizontally, for example during plane-milling. Subsequently the workpiece is placed down and the vacuum is activated. In a matter of seconds, the part is clamped down flat, securely and precisely. Height differences can be compensated via a so-called grid table suction device. With their help, cut-outs for the matrix plates can also be produced without risk.
Matrix plates are optimal for clamping thin workpieces. Even metal sheets can be mounted precisely and without risk of deformation. Clamping workpieces flat prevents vibrations and chatter marks from being caused. It is true, however, that in comparison to magnetic clamping plates, matrix plates have less holding force. Nevertheless, they can be used in the machining of non-ferromagnetic parts, such as workpieces made of aluminum or composite materials. Even thin plates or metal sheets, for which the magnetic field of magnetic clamping plates would provide no hold, can be reliably clamped with the help of matrix plates. Because of their comparably low weight, matrix plates can be used very well as an additional clamping solution. With the help of clamping blocks, clamping brackets, or magnetic clamping plates, they can be quickly and easily mounted to the machine table. For use as a quick change pallet system, they come from the factory partially threaded holes for clamping pins.

If there are narrow spaces in the metal cutting industry, conventional clamping systems quickly approach their limits. Since the boom of modern 5-axis machines, more and more slim and precise tool mountings are requested - or versatile tool extensions, which can be flexibly inserted in almost every interface.
SCHUNK, the competence leader for clamping technology and gripping systems is a pioneer in the field of tool extensions. The innovative family-owned company covers all relevant clamping systems with extensions from their vast toolholder program. TENDO SVL and TRIBOS SVL transmit the advantages of hydraulic expansion toolholders and polygonal technology onto conventional universal toolholders. Tool extensions based on the polygonal technological design are particularly slim. With an L1 dimension of up to 250 mm, and a run out and repeat accuracy of less than 0.003 mm, the one-pieced, maintenance-free "slimming agents" are also suitable for high-precision applications. At the same time, they can be combined with many other toolholders. Practical examples show that even rough working operations are feasible, if high-tensile aluminum is combined with toolholders and polygonal extensions. While a complete polygonal clamping device has been necessary in the past, today’s TRIBOS extensions for tools of a shank diameter up to 5 mm can be clamped in handy and low-priced manual clamping devices. Their required operation pressure is already preset. The operator inserts the extension into the clamping device, turns around the clamping screw with an Allen key, and exchanges the tool. Within 20 seconds the whole process is completed, without worrying about operating errors.

Tool extensions basing on the hydraulic expansion technology are even more flexible in use. The TENDO SVL can be up to 200 mm long, works without a peripheral unit, and transforms each precision toolholder into a highly flexible expert for narrow spaces, no matter which spindle interface is used. The precise run out accuracy, the excellent vibration damping, and the possibility of internal coolant supply provide excellent machining results and long tool lifetimes. As is usual for hydraulic expansion toolholders, a simple Allen key is sufficient for a quick tool change if extensions are used. Since the clamping screw is radially actuated, the tool change is particularly comfortable, and if necessary it can be done directly in the machine. By using intermediate sleeves, the clamping diameter of hydraulic expansion extensions can be reduced by up to 3 mm. Their high torque ensures a safe hold of the tools during drilling, reaming and rough milling operations.

SCHUNK, the competence leader for clamping technology and gripping systems, has enlarged its module program for machine self-service: Following the finger gripper, vacuum, cleaning, and compensation modules, the GSW-M magnetic gripper is also equipped with a 20 mm shank interface, which clamps in a conventional toolholder, and is also connected with the machine spindle. Ferromagnetic components, such as sheet metal, bearing rings, or workpieces with complex contours can be handled time- and cost-efficiently via the machine’s own axes. Moreover, it can be used for bar gripping and finished part acceptance in lathes.
Since the magnetic gripper of the innovative family-owned company is equipped with permanent-magnets, coolant or compressed air is only required for depositing the workpieces. Thus energy is saved, and ensures that the parts remain gripped in case of a sudden pressure drop. Without adjustment or exchange of fingers, the GSW-M can handle various workpieces, even if they are provided with bores or undercuts. On request, several components can be mounted or stacked in piles. The magnetic gripper has a gripping force of 20 N, and is designed for a 1 kg workpiece weight.

Users who have to reach high accuracies during surface grinding can now sharply increase their productivity. Compared to conventional parallel pole technology, the MAGNOS square pole grinding plates from SCHUNK, the competence leader for clamping technology and gripping systems, can achieve an increase in productivity up to 200%. This is due to the use of moveable pole extensions which ensure a homogenous, deformation-free clamping. They are used for grinding flat workpieces, unevenness is compensated, parallelism is ensured, and therefore micron precise grinding operations can be carried out at the first go.
With the MAGNOS square pole technology, multiple grinding operations, repeated retrofitting, and time-consuming support of the workpiece is no longer necessary. If large plates of measuring tables measuring 60 x 355 x 44 mm, made of tool steel 1.2842 (58+4 HRC) are ground, the operation time during surface and parallel grinding can be reduced by 66%. Such effects help to amortize the higher investment costs of the square pole technology in a very short period of time.
In order to be able to adjust the adhesion effect of the magnetic chucks to the individual workpieces, its standard version is equipped with a holding force control. A special attachment to the magnetic chuck even allows machining of very hard workpieces, which can then be easily removed from the magnetic chuck again. MAGNOS square pole grinding plates with pole extensions particularly pay off for surface grinding of large, thin work-pieces with a minimum material thickness of 4 mm. Due to the grid dimensions 32 x 32 mm, small and narrow parts can be also clamped free of deformation. If needed, the square pole plates can be added to existing parallel pole plates for new clamping tasks. Its monoblock design provides a high rigidity and stability, and in turn vibrations are mini- mized, and the surface quality is improved. For a fast adjustment of the workpieces, additional stops can be mounted into the lateral tapped holes. The square pole grinding plates of the innovative family-owned company are available in twelve standardized sizes, and adjustments to individual customer dimensions are possible.

Complete News:
The ability expectations of Service Robots used in the domestic environment are high: They should intuitively adapt to the human, communicate in the usual human way and should even master complex gripping operations. With an Anthropomorphic Gripper Hand, SCHUNK the competence leader for clamping technology and gripping systems, is pushing hard to extend the development of humanoid service robots forward. The design study, which has been introduced at the International Expert Days on Service Robotics 2012, is available as a Right and Left "Hand" for the first time.
It is quite amazing how it resembles its human model, in size, shape, appearance and mobility. Nine drives enable the 5-finger hand to carry out various gripping operations. It has been found that many human gestures can be replicated, thus a visual communication between a human and service robot is simplified, therefore increasing the acceptance of using them in the domestic environment. By using tactile sensors in the fingers, the gripper hand has the necessary sensitivity and can therefore manage every gripping and manipulation task, even in unstructured and unforeseeable situations. Elastic gripping surfaces ensure a reliable hold of the gripped objects. The gripper hand can be connected with lightweight arms via defined interfaces, and SCHUNK has provided the LWA lightweight arm shown here. Christopher Parlitz, Manager for Service Robotics at SCHUNK has said," The 5-finger hand offers new approaches to the research in the field of service robotics in the immediate environment of humans. Studies on human-robot communication show that due to the gesticulating hand, new strategies can now be explored, since the hand allows a realistic form of nonverbal communication".

Complete News:
The electrically driven small parts gripper EGP from SCHUNK, the competence leader for clamping technology and gripping systems, is so easy to control that the conversion from pneumatic to electric gripping modules becomes child's play. Compared with other electrically driven small parts grippers on the market, it scores points with respect to its high speed and simultaneous high gripping force. Its complete electronic system is built into the system and saves space. Brushless, and therefore maintenance-free servo motors, and a powerful junction roller guide ensures high efficiency and makes the gripper a dynamic and high-performance specialist for demanding Pick & Place applications.
Since the EGP is based on the time-tested pneumatic small parts gripper MPG-plus, it offers a bundle of additional advantages: For example, users can completely transfer the sensor system of the MPG-plus to the EGP and convert existing systems from pneumatics to electricity in a flash. Control of the gripper module is the same as for the MPG-plus - either directly (digitally) or by means of sensor distributors. Like the MPG-plus, the EGP also can be bolted through or bolted on either on the side or bottom, for increased flexibility in designing the system. The mechatronic small parts gripper seamlessly integrates into the program of high performance assembly from SCHUNK. It is suitable for various applications in the field of small parts handling and assembly.
In addition, the innovative family-owned company consistently implemented a lightweight construction in the design of the EGP: Excess material is avoided on the gripper housing, and is made of special high-grade aluminum. This enhances the dynamics and energy-efficiency of the higher level system. The EGP is available in two sizes, achieving strokes of 3 and 6 mm. Depending on the size, it is designed for workpiece weights up to 675 g, and has a four-stage adjustable gripping force. The closing time is below 220 ms.

Sophisticated grippers with integrated intelligence

Intelligent mechatronic grippers have a different approach. They are used for shortening manufacturing, assembly and handling processes, and they enable us to develop completely new solution strategies. In the meantime solutions are available, which can be reliably operated without making a comprehensive electronic and control knowledge. Some grippers of the professional league are equipped with Profibus DP, CAN or RS232, but also with an ethernet TCP/IP interface, and an integrated web server, which allow easy actuation via web browser and without additional software. Their characteristic feature is the integrated intelligence, by which the gripper can solve various partial tasks by itself. Therefore gripping commands can be combined with integrated gripped part detection, and a high positioning accuracy at optimized cycle times. The subordinated process controller can be considerably relieved, too. It would be ideal, if the gripper’s range of function could be adjusted with scripts. It is also useful, if the gripper is equipped with additional sensor interfaces, integrated in the base jaws. The occurring forces can be precisely detected and can be adjusted.

Mechatronic handling systems offer distinct advantages: They are very flexible, offer numerous intelligent functions, and despite higher acquisition prices, they quickly pay off. Therefore, it is no surprise that the handling issue is becoming increasingly important in the pneumatics dominating world. This particularly applies, since more and more mechatronic components can be easily operated by average users.
Who doesn’t remember the emerging discussions on digital cameras during their introduction phase in his own circle of acquaintances? Today, the concerns, reservations, and fears seem to be forgotten. Young children or technically inexperienced seniors are using the digital device quite naturally.

The inhibition threshold is sinking

The automation experts are predicting a similar development for mechatronic gripping systems. Since that time it has been possible to reduce the inhibition threshold against the use of these gripping systems, and more and more users, plant designers, and system integrators are taking a mechatronic solution into consideration because of their numerous advantages. Mechatronic grippers are flexible in use and are very comfortably equipped. The grippers are additionally equipped with a control system, which monitors the gripper position, stroke, closing speed, acceleration, and force. Some of the mechatronic modules can be put into operation and are remote-maintained via internet or data line. Even in terms of costs a lot has happened: The rapid progress of electrically actuated servo drives ensures that mechatronic components can be offered at more attractive prices. Even though the initial investment is normally higher than of pneumatic modules, the payback period of mechatronic modules is considerably shorter now. This particularly applies for applications with a high cycle time and many gripping processes, where electrically driven grippers have to use more energy, but are more cost efficient than comparable pneumatic versions. For reasons of environmental protection, mechatronic solutions are compulsory by law in South Korea for example. In the framework of the European safety management for machine and plant designers, mechatronic components have good advantages.

Adaptable gripping modules

The third column of mechatronic gripping systems are the grippers with adaptable, electric drives. Depending on the system and the desired functionality, the modules can be equipped with various servo motors. The two advantages are obvious: The gripper can be used as an additional directly interpolated axis, and can be actuated with the same command set as subordinated robots. This way any gripping position can be easily and flexible changed, without causing problems with incompatible control signals. Moreover, the features of the system’s control unit can be directly used for programming, safety, or field buses.
Since the mechatronic gripping modules offer so many options, question arise if pneumatic grippes will soon be obsolete. SCHUNK, the competence leader for clamping technology and gripping systems considers this unlikely. "Both pneumatic and electrical drives have distinct advantages depending on their use", explains Matthias Poguntke, Business Unit Manager for Product- and Portfolio Management at SCHUNK. Mechatronic modules are particularly flexible, and even though some of them have a higher initial investment, they are very attractive in terms of efficiency. Pneumatic grippers have an attractive price, are robust and can be easily commissioned and maintained. It has to be evaluated according to the purpose, environment and the individual requirements, which type of drive will have the greatest economic benefit. In this connection, SCHUNK sees itself as a competent problem solver, who efficiently bundles pneumatics and mechatronics into one company, and therefore the users can generate considerable synergies. As one of the first manufacturer, the innovative family-owned company bundles a great variety of mechatronic modules in a single modular system, and therefore offers optimum preconditions for a customs-tailored and economic solution.
Simple pneumatic alternatives

There are three central concepts in the market of mechatronic grippers:
  • Mechatronic grippers as a pneumatic alternative
  • Mechatronic grippers with intelligence
  • Adaptable mechatronic grippers

The simplest version of mechatronic grippers, the so-called entry class into the world of mechatronic grippers pursues the aim of replacing pneumatic modules with mechatronic ones. Partly the grippers are based on the proven platforms of pneumatic systems, and make them interesting in two aspects: their use doesn’t require any well-established know-how. Moreover, the grippers are fully mature from the constructive and mechanical point of view, and its pneumatic version has proven many times. The modules can be digitally controlled via a sensor distributor. If the sensor system of the pneumatic gripper can be taken over 100%, the pneumatic grippers of the system can be easily replaced by mechatronic grippers. Moroever, the performance of the mechatronic compact grippers stand the comparison with pneumatic solutions. The entry model as well as gripper’s pneumatic counterpart of SCHUNK, the competence leader for clamping technology and gripping systems are equipped with a high-performance cross roller guide, which ensures a particularly high efficiency factor, high speed, and a high gripping force.

Complete News:
With the PLANOS vacuum clamping system from SCHUNK, the competence leader for clamping technology and gripping systems, flat workpieces as well as those with a flat underside can be clamped on the machine table using vacuum simply, quickly and safely. In order to further enhance the user flexibility, SCHUNK has recently introduced a standardized adapter plate by which the vacuum clamping system can also be used on MAGNOS magnetic chucks.
PLANOS consists of one or multiple combined matrix plates as well as a vacuum generator. During the clamping process, the workpiece is positioned and the vacuum is activated. In a matter of seconds the part is safely and precisely clamped in a level position with a height tolerance of +/- 0.02 mm. It can even secure thin plates precisely and deformation-free. Optional mechanical stops assist in the positioning and accommodate additional shear forces. The vacuum system has a modular design and can be expanded in a variety of ways. It can also be retrofit on existing systems. For this purpose, the matrix plate is secured to the machine table with a quick-change pallet system, clamping blocks, clamping claws or even using a magnetic chuck.
The standardized matrix plates with base bodies made of high-strength aluminum elements are available in the sizes 300 x 200, 300 x 400, and 400 x 600 mm and with grid sizes of 12.5, 25, and 30 mm. The suction surface and the required grid size can be determined depending on the workpiece geometry, the machining and the horizontal forces. The finer the grid, the stronger the holding force. In order to produce breakthroughs, a grid table suction device can be used for the 30 mm grid to elevate the workpiece in its position. On request, the SCHUNK matrix plates can also be equipped with friction pads which are automatically activated through the vacuum feed and permit higher shear forces. Compared with matrix plates without friction pads, the horizontal holding forces with friction pads are up to 30% higher. In the process, no additional force is exerted on the workpiece. The friction pads are resistant to oil and ozone and are individually replaceable if necessary.
To generate the vacuum, the innovative family-owned company offers special vacuum units to ensure maximum flexibility and process safety. They are equipped with an oil-lubricated vacuum pump and a liquid separator, which also serves as a vacuum accumulator. Various components for the system monitoring and interfaces for integration in the machine control ensure maximum safety. An emergency STOP function protects the vacuum pump against damage from suctioned liquids.

"The lathe chuck technology of the future." - this is what the sealed
3- or 6-jaw power chucks type ROTA NCS from SCHUNK are called by those who use them. The innovative lathe chuck from the competence leader in clamping technology and gripping systems combines high clamping forces, maximum precision and minimum effort. In view of the continuously increasing quality requirements in modern metal cutting, the benefits of the ROTA NCS ensure a maximum investment safety.
Hermetically sealed
The engineers from innovative family-owned company have done an excellent job during the development phases of these chucks. With its active jaw pull down, the ROTA NCS achieves top results in terms of face parallelism and perpendicularity. The achieved repeat accuracy achieves less than 0.01 mm! This is an outstanding lathe chuck for high-precision series production.
At the same time, the integrated permanent lubrication provides for a constant jaw clamping force, and therefore for a high efficiency level. Since the ROTA NCS is hermetically sealed against dirt and coolant, it is largely maintenance-free. All functional parts are hardened and ground, which ensures a long lifetime. Due to the low height, the chuck leaves plenty of room in the machining area.

 Rings and castings can be also clamped gently and without deformation
In addition to the 3-jaw version, SCHUNK manufactures the ROTA NCS also as a high-precision 6-jaw chuck. During clamping of thin-walled and uneven components,
the 6 oscillating jaws ensure maximum run-out accuracy and minimum deformation at the workpieces. ROTA NCS 3-jaw power chucks are available in the standard sizes 175, 210, 250, 315, 400 and 500, and the 6-jaw version in sizes 250, 315, 400 und 500.

Combination for tool grinding

The extensions are especially important for tool grinding. Since even thousandths of millimeters decide the quality of the manufactured cutting edge, it is worthwhile to combine toolholders and extensions in a sophisticated way. The combination of hydraulic expansion toolholders and polygonal extensions has proven to be a great solution. Operators thereby achieve excellent runout and repeat accuracies between 0.003 to 0.006 mm at normal tool lengths, measured at the sharp cutting edge. While hydraulic toolholders are dampening the occurring vibrations, the extension optimally sets the tool blank in an upright position. Moreover, this combination ensures a minimum interfering contour which leads to an unhindered interference between the grinding wheel and toolholder, and therefore achieves particularly precise workpiece geometries.
When selecting the optimal extension, the user should consider, if all the required parameters can be met. This is the only way how a minimized interfering contour will not impede the radial stiffness, torque, process reliability or precision. By offering a vast toolholder program, SCHUNK the competence leader for clamping technology and gripping systems is also covering the requirements of extensions for all other relevant clamping systems. Therefore the innovative family-owned company is offering best prerequisites for a system-neutral consulting service, and a custom-tailored solution for any application.

Due to the success of modern 5-axis machines, tool mountings with slim interfering contours have experienced a real boom. With sufficient torque, and high run-out accuracy they allow a deep, collision-free tool path into the workpiece, and thus ensure precision machining, even in areas which are difficult to access. These slim tool extensions are economic, flexible, and can be assembled between tool and toolholder on request. They can be combined with various machine tapers.
Compared to toolholders with a customized taper shape and gage length, the tool extensions are more versatile in use. They are available for various clamping systems, such as heat shrinking, polygonal clamping, or hydraulic expansion technology. The combination of less interfering contours and transferable torques is also an advantage of heat shrinking extensions. However, for heat shrinking toolholders, often an expensive special unit is necessary to change the extensions. Users, who have no heat shrinking unit available, usually choose another type of clamping technology, which works without an expensive peripheral unit. However, if heat shrinking toolholders are already available, and the customer already owns a shrinking unit, heat shrinking extensions can be used economically. The use of hydraulic expansion extensions is recommended only if vibration-damping characteristics or frequent tool change are required. Hydraulic expansion extensions minimize vibrations, and even ensure a high runout accuracy after numerous clamping operations.
Extremely slim

Tool extensions based on polygonal clamping technology are extremely slim. With an L1-dimension of up to 250 mm, a runout and repeat accuracy of less than 0.003 mm, the one-pieced, maintenance-free extensions are also suitable for high-precision applications. The extensions can also be combined with many other toolholders. Practical examples show that expansion toolholders and polygonal extensions can be used for high tensile aluminum roughing/milling operations. Experienced operators are using the polygonal extensions for achieving extreme extension lengths: They clamp several extensions in each other, and still achieve high runout accuracy at the cutting edge, too.
Polygonal extensions for tools with a shank diameter of up to 5 mm can be clamped in handy and low-priced manual clamping devices. The operator inserts the extension into the clamping device, turns the clamping screw with an Allen key to the dead stop, and exchanges the tool. Within 20 seconds the operation is completed, and the number of operating errors is reduced to a minimum. For extensions with a larger diameter universal clamping devices are available, in which polygonal toolholders of any size can be clamped precisely and safely.
Universal application

Tool extensions, which are based on hydraulic expansion technology are the most flexible ones in use. At a length of up to 200 mm, they don’t need any peripheral unit, and transform any precision toolholder independent from the spindle interface into a highly flexible specialist for narrow spaces. The precise runout accuracy, the excellent vibration damping and the possibility of equipping it with an internal coolant supply, provides excellent machining results and long lifetimes of the tools. As it is usual for hydraulic expansion toolholders, a simple Allen key is enough for a fast tool change within seconds. Since the clamping screw is radially actuated, the exchange is very comfortable, and if necessary, it could be done directly in the machine. By using intermediate sleeves, the clamping diameter of the hydraulic expansion extension can be even reduced to 3 mm. Their high torque ensures a save clamping of the tool during drilling, reaming, and finish milling operations. However during rough milling it can make sense to use extensions of the polygonal or heat shrinking technology.

Complete News:
A few thousands of a millimeter in the tool grinding determine the quality of the finished cutting edges. The clamping equipment plays an important role in the process. Its runout and repeat accuracy as well as its vibration behavior have a considerable impact on the grinding result. An example of a precision mount especially well-suited for grinding is the TENDO hydraulic expanding toolholder from SCHUNK, the competence leader for clamping technology and gripping systems. Due to a 25° bevel on the chuck nose, it has a 40% slimmer interfering contour than other hydraulic toolholder. Its runout and repeat accuracy of less than 0.003 mm ensure a consistent removal of material during the grinding process and increase process safety with the grinding of serial tools. In addition, the hydraulic systems dampen vibrations and thereby ensure an outstanding surface quality. The results can be seen for themselves: The good retention of shape and dimensional accuracy on the cutting edge increase the service life of tools by up to 75%. With TENDO, shank tools with a diameter of up to 32 mm can be clamped with a depth of up to 95 mm. Intermediate sleeves further enhance the clamping possibilities. The simple handling, the sealed clamping screw and the long service life make the TENDO hydraulic expanding toolholder an affordable aid for grinding operation.
Extension ensures better interference between grinding wheel and the toolholder

The hydraulic expanding toolholder can be combined with a 100 mm long tool extension of the TRIBOS polygon clamping technology from SCHUNK. Its slim interfering contour ensures that the grinding wheel can run out unimpeded, even if long cutting edges are used. The hydraulic expanding toolholder dampens vibrations and optimally aligns the extension with the tool blank. As a result, the runout accuracy at the sharp cutting edge is increased and extremely precise tool geometries are provided. Both systems are maintenance-free and resistant to dirt, such as tiny grinding particles. This is also an important advantage over mechanical clamping systems, which are composed of several individual movable parts. TRIBOS extensions cover all clamping diameters from 3 mm to 20 mm, and have a runout and repeat accuracy of less than 0.003 mm. Tools can be clamped several thousand times with precision and reliability without showing any signs of fatigue. Combined with the power-actuated TENDO hydraulic expanding toolholder, you can also use this in automated welding processes.

Complete News:
SCHUNK, the competence leader for clamping technology and gripping systems has developed the compact VERO-S NSA quick-change pallet module for automated machine loading. At a repeat accuracy of less than 0.005 mm it allows a fully automated pallet change of the highest precision. The clamping system from the innovative family-owned company is extremely thin, and leaves enough space for the workpiece in the machine and for axis motions. If required, it can be integrated in the machine table.
In order to avoid chips and dirt from endangering the automated changing process, a forced air flow cleans the face during pallet change, and ensures a chip-free contact surface. Subsequently, centering rings take over precise positioning. The module is locked via two clamping slides, providing form-fit, self-locking fixing of the centering ring. Via an air pressure monitoring system, every process step can be monitored reliably: Module open, module closed, and pallet presence.
High pull-down forces

In order to increase product life and process reliability, the functional parts of the NSA plus such as base body, clamping pin, and clamping slide are made of hardened stainless steel. If the turbo function is actuated, the pull-down force of the NSA plus increases up to 30.000 N, and the holding force to more than 100.000 N. The SCHUNK quick-change pallet modules are equipped with a patented double angled clamping stroke, and therefore provide for high pull-down forces. Even in case of demanding volume machining, the robust pallet module ensures reliable and precision clamping. It also absorbs extreme shear forces, whereby the workpiece does not have to change its position. The pallet removal has been also developed in a sophisticated way: The module is unlocked at a pneumatic system pressure of 6 bar. At the same time, a pin lifts the pallet, and thus simplifies the change by a robot or operator.

State-of-the-art technology and ease of use don’t necessarily go hand-in-hand. For the first time, the semi-automatic laser welding machine of the PSM 400 series from SCHUNK Lasertechnik makes both possible. With this machine, small and large components can be precisely machined. Moreover, its ergonomic design prevents fatigue when using for extended periods of time. The latest feature is a new telescopic swivel arm, equipped with monitor, mouse and keyboard, which can be quickly and comfortably adjusted to the individual working position. All the entries can be done in a comfortable seating position. The telecopic swivel arm completes the ergonomic concept of the PSM 400. As in the past, the operator still has convenient access to all machining-, programming-, and control functions, no matter how big the components are. The mobile operation panel with the sensitive joystick can therefore be freely positioned. Moreover, a high-quality swiveling binocular with a swiveling range between 10° and 50° allows for relaxed, high-precision work. An electrically height-adjustable machine table, which can be swivelled to both sides, and an adjustable swivel-mounted laser welding head ensure for maximum flexibility in the working area. And proving that no details were left out, even the ergonomical designed seat can be optimally adjusted to the size and working position of the operator.

The linear directly driven PPU-E from SCHUNK is still the fastest Pick&Place unit on the market. Due to strong demand, the competence leader for clamping technology and gripping systems has enlarged the series by introducing the PPU-E 50 unit. It is highly dynamic, and can handle weights of up to 5 kg. For a complete cycle with a 280 mm horizontal and 105 mm vertical stroke, the PPU-E 50 has a cycle time of 0.92 seconds with a tooling mass of 2 kg and 2 x 60 ms (for gripper).
Both the "small" and the "large" PPU-E unit do not require movable motor cables, which are susceptible to breaking down. With its speedy cycle times and excellent repeat accuracies of 0.01 mm per axis, it is setting standards in the assembly of smaller and medium-sized parts in the electronic, consumer goods, and pharmaceutical industry. All the supply lines for current, control unit, sensor system, and pneumatics are plugged into the rearward, stationary connection. Because of this, cable brakes and plant malfunctions are a thing of the past. The flexible and freely programmable PPU-E 50 is designed for a 150 mm vertical stroke, 280 mm horizontal stroke and a moveable mass of 5 kg. Its maximum acceleration amounts to 100 ms-2, the maximum speed to 4 ms-1.
Excellent repeat accuracy

The narrow housing and the media supply via the backpanel allow a compact, maintenance- and assembly-friendly sandwich construction of several units next to each other. Two integrated position sensors control the vertical and horizontal movement, and ensure the high repeat accuracy. Intelligent controllers can control the cantilever arm and the actuators without a master control system. The required software is already integrated. This way, the unit can be easily commissioned by Plug&Play.
Up to six integrated valves provide all pneumatic tooling with air. This minimizes compressed air and energy, and ensures enormous high cycle frequency. The energy- and time-efficient unit seemlessly fits into the module program of the innovative family-owned company, and can be equipped via a uniform interface with various actuators from the modular system for modular high-perfromance assembly. Besides the basic version without gripper interface, the PPU-E 50 is available in six different configurations: with two, four or six air- and sensor interfaces, electric rotary units, two-fold air- and sensor connections, a vacuum interface, and on option, with a venture nozzle or an aggregate. Moreover, the Z-axis can be equipped with a spring load compensation and a parking brake.

Complete News:
In the assembly of small parts, dynamics, compactness, precision and reliability are essential. The ERD from SCHUNK is an unprecedented rotary module that was particularly designed for assembly applications in the electronics, consumer goods and pharmaceutical industries; the endless rotating miniature module is equipped with two integrated air feed-throughs, four electric feed-throughs and one SIL2-certified absolute encoder measurement system.
The new module enables implementation of space-saving, high-torque, high-speed assembly systems that also comply with the high standards of the Machine Directive. The rotary module from the competence leader for clamping technology and gripping systems is driven by a brushless synchronous motor with permanent excitation. Its special geometry ensures high dynamics and acceleration. Also, due to the optimized air feed-throughs, pneumatic actuators connected to the module can be actuated more quickly. These two combined factors ensure short cycle times and high productivity. The absolute encoder measurement system eliminates the need for time-consuming reference runs during startup and after an emergency shut-down; also, the repeat accuracy is improved, with a specified value of 0.01°. A large number of pairs of poles ensure that the module from the innovative family-owned company generates a high nominal torque of up to 1.2 Nm even at low speeds. The fact that the module has almost no wear parts results in a very long lifetime. As the controller, either Bosch-Rexroth IndraDrive CS or Bosch-Rexroth IndraDrive Advanced drive controllers can be used. The ERD module is available in sizes 04, 08 and 12; these designations also correspond to the respective nominal torque. The modules comply with protection class IP40 or IP54.

Replacement parts, training and warranty services

Users should pay special attention to services during the utilization phase. There are significant differences here, which can have serious economic consequences. It is worthwhile, for example, that support services in the form of replacement parts, repairs and maintenance be offered for the entire life cycle of a system, and not just for the warranty period. To reduce downtimes in case of damage, high delivery readiness, pickup and delivery services, as well as express deliveries are important factors to consider.
SCHUNK, the competence leader for clamping technology and gripping systems, is considered a pioneer in automation services. The innovative family-owned company has continuously expanded its service program for many years already. Today this program encompasses all areas of the life cycle of a system: initial consultation, planning, commissioning work and maintenance. The range of services also includes the SCHUNK long life warranty, a unique 30-year functional warranty for multi-tooth guided gripping modules.

Gripping systems in handling and assembly are often in operation around the clock, seven days a week. Many components have to withstand external influences such as chips, dust, aggressive media or heat. In addition, tight margins and deadlines due to just-in-time production often result in enormous scheduling and planning pressure, usually starting well before the initial commissioning. In view of these challenges, many purchasing decisions are increasingly made based not only on the quality and performance of the modules, but also on the range of services offered. Services increase planning reliability, facilitate commissioning and ensure maximum cost effectiveness during operation.
Many design engineers and purchasing agents long for the times in which grippers, rotary actuators or linear units could be selected based on a small amount of technical data. With the increasing networking of production and assembly processes however, the complexity, range of variants, and therefore the requirements for the planning and implementation process have also increased. Modern services offered by manufacturers can be a valuable aid in this connection. They increase planning security in terms of quality, time, and costs, they shorten the planning phase and enable more effective implementation and therefore a faster start of production.

Reduced planning time - high planning security

The spectrum of useful service tools for the planning phase is large and isn’t limited to the mere provision of an order hotline. It ranges from CAD data download to online configuration programs that facilitate module design, all the way to real test deliveries for examining and even testing modules. Some manufacturers go even further by offering services such as feasibility studies in the form of technical designs, structural tests, FEM analyses, and 3D conceptual designs. Meanwhile, even test set-ups of entire applications are offered by manufacturers as an external service. This can be especially useful if the user's current production process can’t be disturbed and the process reliability of the final solution has to be ensured from the very first day.
Another service is customizing, in which standard components and assemblies are adapted by the manufacturer to individual customer requirements. This can be in the form of mechanical adaptations, such as the development and production of individual gripping fingers and other workpiece-contacting components, as well as software adaptations, such as the implementation of product-specific parameter sets. Diverse services for the development process are also offered: technical cost effectiveness analyses, for example, or the manufacture of prototypes or even the complete contract-related development services.
Commissioning by means of Plug & Work

A second major area consists of services in the implementation phase. The goal of such services is generally to implement projects on schedule and time-efficiently. Both of these factors affect the cost effectiveness, especially if higher level systems are affected by the commissioning. A typical task of service technicians has always been on-site support during commissioning. This generally involves cable and hose connections, parameterization of drive controllers, optimization of electric drives and the training of employees in operation of the system. A further approach of modern service concepts is especially interesting for complex components and solutions. The majority of the commissioning work is transferred to the manufacturer or the system integrator, where the entire application is assembled both mechanically and electrically and then tested for proper functioning and for leaks. This also includes the basic parameterization and the integration of application-specific parameter sets. Such Plug & Work concepts make it possible to minimize commissioning times at the user's location, while ensuring an exact date for the start of production. This approach also minimizes the risk of damage and malfunction-related downtimes during commissioning.
To minimize the user's administrative costs, modern services also include the area of technical documentation. This includes the creation of customer-specific documentation in the national language, as well as the translation of operating manuals or support in the creation of documentation in accordance with company standards. Manufacturers meanwhile also offer parts lists and drawings of workpiece-contacting components.

The three-day "Robot Competiton" has been a hot head-to-head race between the pupils of the Secondary Modern School from Güglingen, which took place at SCHUNK, the competence leader for clamping technology and gripping systems in Lauffen. This competition has been one of about 350 events and campaigns which were carried out between November 28 to December 4, 2011 in the framework of the "European Robotics Week" throughout Europe.
With great enthusiasm the 6th - 10th grade students assembled and programmed the robots and sent them into the race. During the egg and spoon race, collection of balls, and playing chess, both teams proved what they and their robot are capable of. They were supported by six committed professional newcomers, who have been trained as an electronics technician at the innovative family-owned company.
Even though the Red Team lead the event, all participants won, because the aim has been to inspire the pupils for the possibilities of modern robot technologies. This also includes that both teams were personally honored for their performance and commitment by Henrik A. Schunk, the Managing Partner of the high-tech company in Lauffen, who is also the Chairman of the European robotics association EUnited Robotics.

The Secondary Modern School at Güglingen will receive both robot modular systems for the use during their lessons and the working group. Who knows, perhaps one of the participants of the competition, or pupils from the school in Güglingen will occupy himself professionally with robotics. According to Henrik Schunk the professional opportunities for job beginners in this industry are enormous, as robots play more prominent roles in everyday life.

"To offer more than the customer expects", this was the motto of Friedrich Schunk, when he opened his machine shop in a garage in Lauffen, Germany, right after the troubles of World War II. Today, SCHUNK is a German innovative family-owned company and a global player all in one.

According to the mission statement "With a pioneering spirit and perfection, we are setting worldwide standards" Heinz-Dieter Schunk, his son Henrik A. Schunk and his daughter Kristina I. Schunk manage the company. With more than 1,800 employees and a worldwide network of directly owned subsidiaries and distribution partners in more than 50 countries all over the world, SCHUNK is known as the competence leader for clamping technology and gripping systems.
The business unit clamping technology comprises toolholding systems, stationary workholding, lathe chucks, chuck jaws, special hydraulic expansion technology solutions and magnetic technology. The business unit gripping systems produces and distributes gripping modules, rotary modules, linear modules, robot accessories, modular assembly automation as well as automated solutions. The third and youngest business unit is the SCHUNK laser technology.
A double strategy is pursued by the owner family in terms of the product program: on the one hand, they promote the technical development and continuously explore new niches. On the other hand, the company is constantly improving the quality of its existing products. Thus, the world’s largest product portfolio of standard chuck jaws (1,200 standard chuck jaws) was developed, the most extensive range of clamping technology (more than 10,000 standard products), as well as the world’s largest product program for standard grippers (more than 10,000 components).
Over the past 25 years, SCHUNK has grown by more than 12% on average. In 1983, the company had just about 100 employees; twenty years later in 2003 there were already 1,000, ten times as much as in 1983. Today, more than 1,800 people all over the world are part of the SCHUNK family, thereof about 1,400 in Germany. For his life’s work, Heinz-Dieter Schunk was awarded the German Machine Tool Industry Award in 2008. In 2010, he received the Engelberger Robotics Award, the worldwide most prestigious award in the robotics field.

SCHUNK ExpertDays on Service Robotics Industry discovers potentials of service robotics]]> http://www.schunk.com/schunk/schunk_websites/news/news_detail.html?article_id=16981&country=INT&lngCode=EN&lngCode2=EN th. annuel ExpertDays on Service Robotics, hosted by SCHUNK, the competence leader for clamping technology and gripping systems. While the leading symposium for applied service robotics primilarly focused on the issue of applied technologies in the past, this year’s topics were market development and efficiency.

Complete News:
SCHUNK as a pioneer for modular robotics, has promoted the development of service robots from the very beginning. With its industry-proven, mechatronic modules and skillful, polynominal grippers the family-owned company offers a unique modular system for various applications in service robotics. It includes the LWA-4, a modular lightweight arm with the most compact performance on the international market. In almost 100 cooperations with universities, research institutions and highly specialized industrial companies, SCHUNK pushes the development of this new technology forward.

On February 23 and 24, 2011 experts from all over the world met at the 4th annuel ExpertDays on Service Robotics, hosted by SCHUNK, the competence leader for clamping technology and gripping systems. While the leading symposium for applied service robotics primilarly focused on the issue of applied technologies in the past, this year’s topics were market development and efficiency. By means of numerous practical examples, it became clear that service robots have left the stadium of university research, and are increasingly used by industrial companies for specific applications.
Service robotics is gaining greater momentum from an economical point of view which was proven to be true at the ExpertDays: nine of the 18 speakers came directly from the industry. Polysius AG markets a fully automatic laboratory automation system for quality control during the cement production process. Audi AG intensively researches on service robots for picking of parts in the automotive industry, Harris Corp. uses service robots for bomb disposal, and Infineon Technologies AG controls the air quality in cleanrooms with service robots.

Professor Dr. Henrik I. Christensen, holder of the "KUKA Chair of Robotics" at the Georgia Institute of Technology in Atlanta, USA said that the developments so far have been ignored the market. Solutions are technologically mature, but are too expensive for real-world applications. He urged for a change from technologically driven researches to market- and price-orientated developments. If costs keep within the budget, said Christensen, service robots can open up their markets. Paying $200 to $300 for a household robot is realistic. In the healthcare industry, the price limit is about $10,000. User- or consumer-orientated interfaces are equally important. Then robots can be served by robotic armatures, too. Moreover he recommended to design service robots for special applications. In the healthcare field, for example, the focus must be more on the manipulation and navigation, in the logistics however cycle times must be lower than 6 seconds, and the grippers have to be robust and flexible.

You will find information and photos on the SCHUNK ExpertDays on Service Robotics on the internet at www.expertdays.schunk.com. Also a facebook group was set up at www.expertdays.schunk.com/facebook. The date for the 5th annuel SCHUNK ExpertDays on Service Robotics is already in place, and will take place on February 29 to March 1st, 2012.

This event made clear that standardized platforms and components can contribute to economic and highly developed solutions. This applies for light-weight arms or flexibly applicable grippers, but also for mobile platforms or control units. Binding standards from ISO standard to the CE-marking up to nationals standards, as they are currently developped in South Korea, should facilitate the market entry of service robots. According to Prof. Alois Knoll of the Technical University in Munich, system integrators are required, which are specialized for individual fields of application. They should close the gap in future, between manufacturer and user. In Christensen’s opinion, system integration is a substantial portion of the value creation, and the function of a system integrator can be very interesting from the economic point of view.
Even visionary approaches were introduced at the 4th annuel SCHUNK ExpertDays. Dr. Amos Albert of Robert Bosch GmbH sees a considerable potential in semi-autonomous service robots. If you do not have your own solution strategy, you can be assisted by a central support. The so-called "Click-Worker" may be organized like a call center. If needed, they can connect to the robot, solve the problem and release the robot into its autonomy again. A concept of Dr. Markus Waibel from the Federal Technical University in Zurich went a step further. He searched for a central knowledge store, in which countless data, models, applications and programs are stored, which can be independently called off by the robot itself. The idea is amazingly easy: All the connected robots, developers and system integrators can use a common pool of knowledge, with successful solution strategies, and put self-developed strategies into the system.

Complete News:
The PHL from SCHUNK outperformes in efficiency and design

The newly developed PHL long-stroke gripper from SCHUNK combines in a unique manner, technological know-how and functional, appealing design. As one of the first long-stroke gripper ever, it optionally disposes of a multi-tooth guidance or a profiled rail guidance, which considerably increases the module’s degree of efficiency. For this successful symbiosis, the gripper was recently awarded with the iF Product Design Award 2011.
The PHL in modular design from SCHUNK, the competence leader in clamping technology and gripping systems is offered in 90 standardized versions. The design of every version remains unchanged, and thus a high recognition value of the gripper is assured. With the PHL over-sizing can be avoided, the consumption of compressed air and energy are minimized, and the required space of applications is reduced. Efficient gripping of large strokes is also possible.

Compact powerhouses reduce costs

Within the design concept from this innovative family-owned company, light-weight design aspects were considered, and the functional aspects of a modular system. With jaw guides and a powerful multi-tooth guidance, the PHL is particularly suitable for rough environments. It is equipped with roller bearings and profiled rail guidance, achieving a 25 % higher degree of efficiency. The guide carriage of the gripper fingers are ball seated, minimizing friction and assures an optimum power distribution. Due to the closed, permanently lubricated linear roller guide, the payload capacity of the gripper increases and wear reduced. Users benefit from the permanently reliable precision and a long lifetime of the component. With the PHL SCHUNK blurred the boarders between standardized and individual solutions. Length and stroke of the PHL can be individually defined. The individual solution becomes standardized at an ideal price-performance ratio.
The new gripper generation from SCHUNK clearly exceeds the performance of conventional long-stroke grippers with T-slots or round guidance. For many applications smaller, low-priced gripper sizes will meet the requirements now, which have a lower compressed air consumption and therefore are more efficient. Alternatively, longer fingers can be used at an approximately identical gripping force. With its long stroke, the PHL is suitable for handling large components, as well as for batch production, where various workpiece sizes are manufactured on one single processing line. Components with large undercuts can be gripped safely, too.

Modular concept allows enormous diversity of variants

For grippers with the multi-tooth guidance, or the profiled rail guidance, five sizes with piston diameters between 25 and 63 mm are available. The user may choose between three strokes per size, so that every stroke between 30 and 160 mm is covered. Moreover, the gripper can be equipped with springs for gripping force maintenance for I.D. and O.D. gripping. All in all 90 standardized versions are available. The largest size of the PHL provides a gripping force of 3500 N, and a maximum admissible finger length of 600 mm. On option for every size, a version with special viton seals or a high-temperature version for hot environments of up to 130 °C is available. The gripper position can be monitored via inductive proximity switches, or via magnetic switches. For this purpose, the gripper is already equipped with an integrated sensor groove.

During the 41 International Symposium of Robotics 2010, Heinz-Dieter Schunk, CEO of SCHUNK, in Lauffen, Germany, received the Engelberger Robotics Award. The Engelberger Award is considered to be the most prestigious award in the robotics field. It honors individuals, who have provided outstanding contributions in the areas of technology development, application, education, and leadership. The award is named after Joseph F. Engelberger, the founder of industrial robotics and father of the modern robot industry.

The prize has been awarded since 1977 by the Robotic Industries Association (RIA) trade organization in North Amercia. Leading robot manufacturers, suppliers and system integrators, operators, research groups, and consulting agencies make up the 250 members of the RIA.

Pioneer in Gripping Technology
 
Heinz-Dieter Schunk is a pioneer in the field of gripping technology. He recognized early on, that gripping would play a leading role in automation, and thus for robotics, too. He was one of the first engineers to develop standardized gripping modules. Today, SCHUNK is considered to be the worldwide competence leader in clamping technology and gripping systems. The SCHUNK program has more than 10,000 standard components. Among the many benefits, operators profit from the worldwide largest gripper program, the largest mechatronic gripper spectrum and from the 30-year functional warranty on multi-tooth guided gripping modules, which is second to none.
SCHUNK has kept its claim for leadership until today. As a pioneer in modular robotics, the company offers a vast modular system, from which various robot structurs for industry and research can be individually configurated. The modular lightweight arm, but also the multi-functional gripping hand SDH-2 have the highest compact performance; combined, highly flexible systems with 14 or more axes can be quickly configured.
SCHUNK Expert Days is the leading symposium for applied service robotics and has ties with over 100 universities, research institutions and highly specialized industrial companies. With this program, SCHUNK promotes the development of modular robotics and paves the way for completely new fields of applications.

The all-rounder
 
In order to create the process- and plant design more flexible for design engineers, the module can be screwed through, fastened laterally, or from the bottom. Besides the inductive monitoring, the MPG-plus can be monitored via integrated and programmable magnetic switches. No big disturbing contours arise, because the sensor only detects two positions, "open" and "closed". In order to increase process reliability, additional switching points can be programmed. Therefore even at very low strokes a safe position monitoring and detection of various workpiece sizes is possible.

With the MPG-plus Miniature Parallel Gripper, SCHUNK brings about new solutions for the handling of small components. Compared with similar modules which require the same input, the new SCHUNK gripper for small components achieves a considerably higher output, clearing the way for smaller and more efficient systems. At the Automatica show 2010, this power gripper received the MM Award in the category "gripping technology" of the renowned magazine MM MaschinenMarkt.
The combination of an oval piston drive and roller bearings assure an enormous degree of efficiency for this compact powerhouse, and makes it to the most efficient miniature parallel gripper on the market. Due to the high force and moment loads, units of the same size can be equipped with longer gripper fingers and higher gripping forces are achieved. Alternatively, design engineers and operators can work with a smaller size at an identical power requirement. If the gripper should be equipped with micro valves, the actuation time can increase by up to 100 per cent. This booster in productivity saves valuable compressed air, and annoying assembly work.

Up to 25 % higher gripping forces
 
Compared with the previous MPG, the gripping force of sizes 40 increased from 110 amounts to 140 N, which is an increase by 25 per cent. The maximum admissible finger length is now 60 mm, instead of 40 mm. In other words, instead of size 50, size 40 will be enough for future applications.
 
By increasing the number of the cross roller guidances, the force is distributed more evenly, making the average basic load rating increase by 30 percent. This causes the bearing capacity of the complete guidance to improve, wear-out is reduced, which boosts the life of the gripper. For achieving a much higher precision, the roller guidances are individually adjusted. This makes them very stable and able to run smoothly

Light-weight design reduces the gripper weight
 
The MPG-plus was designed to be light-weight. Therefore, surplus material of the gripper housing was reduced. Moreover, inner components are made from special high-tensile aluminum now, and the weight of all gripper sizes was reduced on average by about 10 percent. In turn dynamics of the higher-ranking units can be increased.
