Abstract
The machine tool includes a spindle rotor, a tool receptacle and a clamp for clamping a tool in the tool receptacle. The clamp is moveable in the direction of the spindle axis by a spindle drive which is actuated by rotation of the spindle rotor. A spreading member is provided in the tool receptacle for positive gripping and clamping of the tool. The spindle drive preferably includes an externally threaded section on the spreading member and an internally threaded section on the tool receptacle, the latter being non-rotatably joined with the spindle rotor.
