Schunk supllies `tandem` clamping force block, which is a classic vice among stationary workholding systems. The compact power packs are aptly designed for use in a very limited space and can be operated either pneumatically or hydraulically. Salient features of the clamping force block power pack include - clamping repeat accuracy of 0.01 mm, high clamping forces up to 50,000 n,ensuring possibility of pressure maintenance during machining top jaws for individual production and compatibility with schunk unilock quick change pallet system. Due to optimized wedge hook geometry, clamping force block tandem pzs [pneumatic or hydraulic] supplies a high clamping force and large stroke.
