Schunk VERO-S NSE

The Thinnest Pneumatic Quick-Change Pallet Module in the World

Schunk introduces the flattest pneumatic quick-change pallet in the world, VERO-S mini. The patented drive concept of the VERO-S NSE mini consists of a fast stoke and a clamping stroke, and ensures a highly compact performance. At a module diameter of 90mm, and a clamping pin diameter of only 20mm, the NSE mini also has integrated turbo function and pull-in forces of up to 1500 N. The clamping pin is positioned via a short taper and is fixed with three clamping slides. Locking is done mechanically via spring force. It is self-locking and form-fitted. The large contact surfaces between clamping slide and pin minimize the surface pressure in unclamped condition, and also the wear of the module.

Since the minimum clearance between two clamping pins amounts to 100mm, the NSE mini has variable gages for bore holes for workpiece and pallet clamping. It provides flexibility in the field of zero point clamping, making it so that even small workpieces can be directly clamped, and are completely machined from five sides without restricting accessibility. For this purpose, the clamping pins of the Quick-Change Pallet Systems are directly screwed in the workpiece. The components are quickly exchanged in the machine, and are positioned, fixed, and clamped in the Quick-Change Clamping Modules at a repeat accuracy of less than 0.005mm. In order to optimize accessibility, the clamping height of the workpieces can be adjusted with module height extensions, and therefore the machine spindle can reach all five sides of the workpiece without needing special tools.
   
All functional components, base body, clamping pin, and clamping slide, are made of hardened stainless steel. Moreover, the maintenance-free modules are completely sealed and, therefore, protected against chips, dust, and coolant. In order to avoid chips jamming in the module during workpiece change, the base plate can be provided with a bore hole for an air purge connection underneath the opening of the clamping pin. If the modules will be automatically loaded, the clamping slide positions can also be monitored.
