Schunk, the competence leader for clamping technology and gripping systems continues to enlarge its program of VERO-S Quick-Change Pallet System (discovered at EMO 2011). With a height of 20 mm, the VERO-S NSE mini module from Schunk is the most flat pneumatic quick-change pallet module in the world. This provides ideal conditions for retrofitting existing machines, making full use of the engine room, and allows direct clamping of small workpieces.
Since the VERO-S NSE mini has small gauges for bore holes, small workpieces can now be directly clamped.
The patented drive concept consists of a fast stroke and a clamping stroke, and ensures that the compact module of the innovative family-owned company has a highly compact performance. At a module diameter of 90 mm, and a clamping pin diameter of only 20 mm, the NSE mini also has integrated turbo function and enormous 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.
Fast and precise Since the minimum clearance between two clamping pins amounts to 100 mm, the NSE mini has particularly small and variable gauges for bore holes for workpiece and pallet clamping. It provides flexibility in the field of zero point clamping which has never been seen before. Even small workpieces can be directly clamped, and are completely machined from five sides without restricting accessibility of the lathe chuck or chuck jaw. 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 the Quick-Change Clamping Modules at a repeat accuracy of less than 0.005 mm. 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.

PS: We will come back on Schunk innovation later (we’ve seen a prototype of light-weight gripper made of … wood!)
