ABSTRACT:
A machine tool, such as a lathe, comprises a rotary workpiece spindle and a tool turret assembly which comprises a main turret and an auxiliary turret each carrying a plurality of tools. The main turret is pivotable about an axis parallel to the axis of the workpiece spindle, the auxiliary turret being pivotably mounted on the main turret eccentrically with respect to the pivotal axis of the main turret, so that each tool on the auxiliary turret can be selectively brought into an unobstructed operative position in a predetermined inoperative angular position of the main turret.
