Zusammenfassung:	A machine tool is provided with two turret heads indexably mounted in spaced relation on a common carriage. One of the turret heads rotatably mounts a plurality of tool spindles for drivingly receiving rotary cutting tools. The other of the turret heads fixedly supports a plurality of stationary cutting tools. The tool spindles are rotated by a driving device having a power source common to a workpiece driving device wherein the workpiece is rotatable about its own axis. The common carriage is movable either in the axial direction or in the radial direction of the workpiece. An indexing device is selectively connected to a main spindle mounting the workpiece supporting device for angularly indexing the workpiece and another indexing device selectively indexes the turret heads for angularly positioning a desired tool in a machining zone.
