F-Tool ZPS The F-Tool ZPS is a simple, precise, powerful zero point clamping system. The positioning takes place by means of conically cut clamping pins which compress the centring ring during clamping and form a friction-locked connection with the base unit. This compensates for any lateral clearance. The pallet can be fastened to the ZPS base unit mechanically using screws or by means of an additional independent clamping mechanism.
