ABSTRACT:
A spindle of a machine tool is mounted for rotation about a longitudinal axis. The spindle comprises clamping means for clamping and releasing a tool. An energy accumulator is charged when the tool is not clamped and is at least partly discharged to tighten the clamping means when the tool is clamped. An actuating unit serves to charge the energy accumulator by means of an external force supplied via a connection. To enable employment of the spindle at very high speeds, the actuating unit and the connection are arranged in the rotating part of the spindle. The spindle rotates at at least 30,000 revolutions per minute and the connection is a releasable plug or screw connection.
