ABSTRACT:
A machine tool wherein the carrier for several rotary work spindles is separably mounted on a base in such a way that the chucks of two spindles are spaced apart by equal distances from horizontal ways for two side slides each of which mounts a carriage for an indexible tool turret. If the treatment of a workpiece at one of the working stations takes up more time than the treatment of a workpiece at the other working station, the tools which have completed the treatment of a workpiece at the other station are moved to the one station to cooperate with the other tools in rapidly completing the treatment of the workpiece at the one station. The carrier may be a box-like structure with two spindles or a drum having more than two work spindles and being indexible in a headstock, which is separably secured to the base.
