Abstract
In a quick-action clamping device for axially securing a disk-shaped tool, particularly a grinding wheel on a flange of a driven spindle that has a clamping part provided with a thread that can be screwed to the thread of the spindle. The disk-shaped tool is held clamped between contact surfaces of the flange and the clamping part whose spacing from one another can be changed. It is proposed to avoid complete release of the tension nut during spindle stop operation in that the tool is pressed against the flange by means of at least one additional holding surface via a spring force, and that this additional holding surface is connected to the spindle in a manner secured against relative rotation.
