Provided in the clamping surface of a chuck (1) actuated by a taper element (2) are annular grooves (4) in which toroidal sealing rings (5) of elastomeric material are arranged, the diameter of which is greater than the depth of the grooves (4). Thus workpieces can be reliably clamped while avoiding undesirable deformations or damage; rotationally symmetrical clamping can also be obtained in the case of workpieces whose profile does not completely coincide with a circular profile. <IMAGE> |
