ABSTRACT:
A force actuated clamping chuck has a chuck body with a central bore and at least two clamping jaws that are guided in radial jaw guides of the chuck body. The radial jaw guides have opposed sidewalls with a plurality of guide grooves which are engaged by a plurality of guide ribs provided at lateral surfaces of the clamping jaws. A clamping piston is axially guided in the central bore and has a throughbore for receiving a workpiece. The clamping piston has key grooves provided at the periphery thereof. The clamping jaws have a key member at an end thereof facing the clamping piston. The key members engage the key grooves. At least two of the guide ribs extending over the entire radial length of the clamping jaw have a trapezoidal cross-section. At least one of the guide ribs, extending over a portion of the radial length at an end of the clamping jaw remote from the clamping piston, has a trapezoidal cross-section.
