<p>The manually operable jaw chuck (1) has a base body (4) operable on a machine tool, where radially movable clamping jaws (6,7,8) are attached for fixing a work piece (2) on the base body. A wedge bar (9) is arranged in the base body in the area of a threaded spindle (24), where a radially movable centering device (11) supported on the base body is laterally displaced from one or more clamping jaws. The centering devices are operable together in a synchronized way and independent from each other or independent from the clamping jaws.</p> |
