Flexible rotary modules: compact, precise and dynamic Current discussions about the smart factory and Industry 4.0 can easily give the impression that the advantages of mechatronization can be attained only through radical change – a big bang, so to speak, in production automation. The exact opposite is the case: design engineers are increasingly recognizing the potentials of mechatronic components and are already using them effectively today. This also includes the mechatronization of rotative movements. There are good reasons why SCHUNK, the competence leader for clamping technology and gripping systems has expanded its line of standard gripping system components with respect to electric rotary modules. Módulos flexibles rotatorios: Compacto, preciso y dinámico Whether for highly dynamic electronic assembly, freely positionable rotary indexing tables for assembly applications or powerful rotary actuators for heavy loads – the world’s most extensive line of mechatronic modules from SCHUNK, with more than 300 standard components, offers the right mechatronic rotary module for every dimension. Particularly for assembly applications in the electronics, consumer goods and pharmaceutical industries, for example, SCHUNK developed the endlessly rotating SCHUNK ERD miniature module, the world's only torque motor with an integrated air feed-through and absolute position measuring system. The module features two integrated air feed-throughs as standard equipment. Available options include four electrical feed-throughs and the SIL2-certified absolute position measuring system. The SCHUNK ERD, which is available in three sizes with nominal torques of 0.4 Nm, 0.8 Nm and 1.2 Nm, can be used to implement space-saving, high-torque and high-speed assembly systems that also fulfill the stringent requirements of the machine directives. The rotary module 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 position measuring 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 mm. A large number of pairs of poles ensures that the module generates a high rated torque of up to 1.2 Nm even at low speeds. The module can be controlled for example using Bosch-Rexroth IndraDrive CS drive controllers. Minimal interfering contours The versatile SCHUNK ERS rotary module was developed for rotary motions in the middle load range, which is most in demand. The most compact mechatronic rotary module currently available on the market has a height of only 66 mm in size 170. It achieves a rated torque of 5 Nm and a maximum torque of 17 Nm. This module enables the design of very versatile and compact systems. In assembly applications it can be used either as a rotary module or as a small rotary indexing table. The core component is a hollow shaft torque motor, which makes it possible to build a very lightweight and compact module that operates completely wear-free and therefore extremely efficiently. With its endless rotation at speeds of up to 250 rpm it can approach any intermediate positions at a repeat accuracy of 0.01°. As opposed to rotary modules with a conventional servomotor the ERS has no additional interfering contour. Elasticity from backlash and friction is also eliminated. Instead, the durable module features high acceleration, high turning speed and high precision. An optional pneumatic brake can be integrated to ensure reliable holding of single positions. A large center bore allows the feed-through of cables or workpieces, as well as the use of a camera. But that is not all. To conduct compressed air or signals directly without the use of hoses or cables, the compact module is also available in a version with pneumatic/electric feed-through, in which a slip ring or air duct enables the feed-through of up to eight electrical signals (24 V DC/2 A) and one fluid with a pressure of up to 8 bar. The SCHUNK ERS is available in three sizes with outer diameters of 135 to 210 mm. The version with a rotary feed-through is available in two sizes with outer diameters of 170 and 210 mm. To ensure maximum versatility in the control strategy, the modules can be operated with the SCHUNK ECM motion controller (48 V version) or with a standard controller, for example from Bosch or Siemens (560 V version). Free choice of motors The electrically driven SCHUNK ERM rotary module shows the tremendous advantages of using mechatronics also for heavy loads. This module combines high torques with high precision. That makes it ideal for the variable and precise positioning of heavy loads, such as for turning and reorientation of workpieces in automotive production. Spontaneous changes in the handling process and constantly changing parts families can easily be programmed to increase versatility in the process design. This also facilitates commissioning, since the ERM modules allow fast and precise fine adjustment of tolerances during system engineering, which is not possible with pneumatic rotary modules. In addition, it is possible to operate the modules at reduced speed during set-up or maintenance, which not only prevents damage, but also significantly reduces the time needed for the initial system start-up. The adaptive design of the ERM modules allows the use of all standard industrial servo motors. This provides a very high degree of freedom with respect to the control strategy. Equipped with the right motor, the properties of the system controller with respect to programming, safety or field buses can be transmitted directly to the module. Compensation of the different regional standards in Europe, USA and Asia is therefore relatively easy. In addition, the auxiliary gearbox, which turns in 4x90° steps, allows optimal adaptation of the interfering contour of the rotary module and drive unit for use with gantries. A standard center bore of 22 mm enables a very compact and uncluttered system design. Eight air feed-throughs supply compressed air to the pneumatic actuators downstream of the rotational axis. In size 160 the maximum output torque is 75 Nm and the maximum driving torque is 2 Nm. Compact powerhouses At the upper end of the performance scale SCHUNK offers three compact and intelligent high-performance rotary modules, which are optimally designed for robust use in industrial applications: SCHUNK PR 2, PDU 2 and PSM 2. These modules feature fully integrated electronic control and power components. This eliminates the need for an external controller and minimizes the number of cable connections, as well as fault susceptibility. The powerhouses are available in three standard sizes. They are controlled either via Profibus (up to 12 Mbit/s) or CAN-Bus (up to 1 Mbit/s). The modules are equipped with a USB device port for commissioning and parameterization via PC with the SCHUNK Motion Tool. Manual addressing is possible via a convenient rotary code switch. Initial module movements can be achieved manually by the use of DIP switches. The status is indicated via an LED display. Due to harmonic drive gears the PR 2, which is designed as a rotary module, and the PDU 2, designed as a linear axis module, achieve very high torques between 16 Nm and 184 Nm, depending on the size. The direct drive PSM 2 is ideal for moving small loads faster. With a torque of up to 1.8 Nm the compact module reaches speeds of up to 4,320 rpm. Individual control of the position, speed and torque is possible with all three modules. An incremental encoder ensures high positioning and repeat accuracy. The integrated brake allows reliable holding of the single positions.

Low-maintenance power lathe chuck with permanent lubrication and through-hole Constant clamping forces, minimal maintenance costs as well as high energy efficiency, and productivity are assured with the versatile SCHUNK ROTA NCA power lathe chuck. With its large dimensioned through-hole for automated bar loading and its convenient clamping range, the weight-reduced lathe chuck covers an extremely wide range of applications. The special geometry of the chuck body makes it easy to access tools, meaning that the ROTA NCA is especially suitable for use on modern turn/mill centers. In addition, the weight-reduced design ensures high energy efficiency as well as reduced acceleration, and deceleration times. The special sealing increases process reliability The special seal system located on the fine-serrated base jaws prevents grease from being flushed out and the clamping force from being lost gradually. Compared to conventional power lathe chucks, the lubrication intervals are extended by a factor of twenty. In addition, the seal prevents chips or dirt from penetrating the chuck body. To ensure maximum process reliability, all functional components are hardened and ground. The fine-serrated power lathe chuck (1.5 mm x 60° or 1/16"x 90°) is available in five sizes from 160 mm to 330 mm diameter with maximum clamping forces of 45 kN to 160 kN and through-holes of 32 mm to 104 mm for speeds from 3,500 rpm up to 5,500 rpm. The jaw stroke is a uniform 5.3 mm. The lathe chuck can be directly adjusted to the machines via an integrated interface.

A tool cart minimizes the risk of cut injuries From practice for practice – according to this motto, SCHUNK, the competence leader for gripping systems and clamping technology, developed a compact tool cart for up to 156 tool mountings that provides the best protection against cuts in everyday operation as additional storage for the machine due to its trademarked push-fit system. "The tool cart is the result of an internal continual improvement process at the SCHUNK competence center for lathe chucks and stationary workholding in Mengen," explains Markus Michelberger, Head of Sales Workholding Systems at Heinz-Dieter SCHUNK GmbH & Co. Spanntechnik KG. The catalyst for this development was a typical occupational accident in the metal cutting – when removing a tool from the customary shelving system, a machine operator cut their forearm on the edge of a neighbouring tool. As part of the process of continuous improvement, a research project was started with the aim of minimizing the risk of injury when handling and storing tools outside of the machine. Free access to tools The carts made such an impression when put into practice that SCHUNK has now equipped every machine at the Mengen plant with an efficient, mobile storage rack. "Since customers always ask us about the tool carts during plant visits, we have decided to add these to our standard program," reports Markus Michelberger. The stainless steel push-fit system of the SCHUNK tool cart is designed in a way that the sharp cutting edges are always angled away from the machine operator while it is still possible to get safe access to the tool taper. Because there are gaps for the slots on the opposite side, the toolholder mountings with long tools can also be stored and accessed. The cart is delivered completely pre-assembled and is fitted with industrial rollers and handles for moving safely between tool presetting and the machine. It is available in two sizes and can be custom fitted with slots for interfaces BT 30, 40 and 50, SK/CAT 40, 50, CAPTO C6, HSK-A 40. 63 and 100. A drain pan for coolant is available as an option.

A new flagship for quick-change pallet technology SCHUNK, the competence leader for gripping systems and clamping technology, is introducing two premium quick-change pallet modules with unique features on the marekt: The VERO-S NSE3 138 quick-change pallet module and the VERO-S NSE-T3 138 tombstone module. Their most striking feature is an optional spring-actuated cone seal that automatically locks the module's changing interface as soon as the clamping pin is lifted. In combination with the integrated blow-out function, the quick lock prevents chips or dirt from lodging into the interface. Without changing the height, it locks the last gateway of the otherwise completely sealed modules. Pull-down force and rigidity have been increased even further SCHUNK has yet again boosted the performance characteristics of the VERO-S NSE3 138 as compared to previous top sellers. An enormous pull-down force of 8,000 N or 28,000 N with activated turbo function as well as increased dimensional stability for the module body have a positive impact on the rigidity of the clamping solutions. Thus, even the highest tilting moments and transverse forces can be reliably absorbed when parts are clamped at the base are machined on at height, for example. Clamping and positioning also occur via a short taper with a repeat accuracy of < 0.005 mm with the premium modules. This ensures maximum precision even in the most demanding applications. Due to the conical fitting, the clamping pins can also be joined into the modules eccentrically, making this process incredibly easy. The actual clamping is done via spring force without any external energy supply; it is form-fit and self-locking. The workpieces remain safely clamped in case of a sudden pressure drop in the air system. A pneumatic system pressure of 6 bar is sufficient to open the clamping modules. Convenient monitoring For maximum process reliability, both clamping slide positions "open" and "closed" can be queried as standard using dynamic pressure. On option, a position sensor can be used, which additionally detects a locking process without pins. Depending on the thread diameter of the clamping pins have holding forces of 35,000 N (M10), 50,000 N (M12), or 75,000 N (M16). All components, such as base bodies, clamping pins, and clamping slide, are made of hardened stainless steel, making them absolutely corrosion-resistant and extremely long-lasting. Special support areas facilitate cleaning and ensure a perfectly flat contact surface for the clamping devices and workpieces. The new premium modules are fully compatible with the previous VERO-S modular system, which now consists of more than 1,000 possible combinations for highly efficient workpiece clamping.
