Abstract
A chuck body for a clamping chuck for clamping a workpiece has a substantially rotationally symmetrically formed basic body, provided on which is a receiving opening, which is formed as a portion of a cone and is formed for receiving a clamping head in such a way as to transmit force. Attached to the basic body is a deformation sensor, for example as a strain gauge, which is intended and designed for determining a deformation of the basic body in a circumferential direction. In this way, the condition and state of wear of the clamping chuck can be determined.
