With a height of only 20mm, the VERO-S NSE mini module from Schunk Intec Ltd
(www.gb.schunk.com) is suitable for retrofitting to existing machines, giving the end user full use of the work envelope and the direct clamping of small workpieces.
A patented drive mechanism gives a fast stroke and a clamping stroke; and although it has a diameter of just 90mm and a 20mm-diameter pin, it can exert a pull force of 1,500N. The clamping pin is positioned via a short taper and is fixed with three clamping slides. Locking is done mechanically via a spring-actuated self-locking mechanism. The units provide flexibility in the field of zero-point clamping, and even small workpieces can be directly clamped and completely machined from five sides without interference.
For this purpose, the clamping pins of the Quick Change Pallet Systems are directly screwed into the workpiece. The components are quickly exchanged in the machine and are positioned, fixed and clamped in the Quick Change Clamping Modules with a repeat accuracy of better than 0.005mm. In order to optimise accessibility, the clamping height of the workpieces can be adjusted with module height extensions, allowing a machine spindle to reach all five sides of a workpiece without special tooling.
All functional components for the NSE mini and all the other VERO-S modules — such as the base body, clamping pin and clamping slide — are made of stainless steel for maximum service life. Moreover, the maintenance-free modules are protected against chips, dust and coolant.
