To check the flat or planar clamping of a workpiece in the jaws of a chuck, and/or to measure the respective clamping jaws, a pressure responsive signal transmitter is provided in at least one of the contact surfaces of a clamping jaw 6 or in an elastically deformable zone, which can be electrically coupled to measuring instruments provided outside the chuck body, in order to evaluate the signals. This makes it possible to find out, before starting the operation of a machine tool, whether the workpiece is correctly clamped, and with what clamping force. |
