ABSTRACT:
To so improve a machine tool comprising a machine frame, a rotary table mounted on the machine frame for rotation about a center axis, machining stations arranged around the rotary table, at least one holding device mounted on the rotary table for rotation about an axis of rotation, and a rotary drive, that during rotation of the rotary table from machining station to machining station, rotation of the holding device through optionally small or optionally large angles is possible, it is proposed that the rotary drive comprise a first and a second cam track held stationarily on the machine frame and a first and a second cam element mounted on the rotary table so as to move along the cam track as the rotary table rotates, that the first cam track be located in a first surface and the second cam track in a second surface, and that the first and second cam elements be coupled for rotating the holding device and in each of their positions along the cam tracks hold the holding device in a clearly defined rotary position.
