Abstract
A clamping chuck having a central receptacle and a disk arranged around the receptacle and which may be moved from a clamping position, whereby a draw bar inserted into the receptacle is clamped, to a releasing position wherein a draw bar is released from being clamped. The disk has a locking mechanism including a plurality of locking elements which are equally spaced in a circumferential direction. The draw bar is coupled to a brake such that the braking force of the brake is proportional to a pull on the draw bar. Thus, a high axial load on the draw bar causes a high braking force and a low load results in a low braking force.
