In a diaphragm chuck (3) with clamping jaws (3) which are in a drivable connection with a deformable diaphragm (4) by means of jaw carriers (6) and in which counterweights (8) allocated to the clamping jaws (3) are inserted in the chuck body (2), the clamping jaws (3) are provided with axially aligned joining pieces (23) which are held in the counterweights (8). The clamping jaws (3) can be clamped together with the jaw carriers (4) and the diaphragm as well as with the counterweights (8) by means of quick clamping devices (31) which engage in the joining pieces (23). This embodiment achieves a situation in which the clamping jaws (3) can be changed rapidly and in a straightforward procedure by releasing the quick clamping devices (31) by means of a tool which can be inserted radially from the outside into the chuck body (2). Furthermore, the clamping jaws (3), the jaw carriers (6) and the counterweights (8) form a unit which is chucked in itself, which possesses a high degree of rigidity and also no impurities can achieve ingress between these components.
