Abstract
A computerized numerical control automatic complex lathe has a main spindle for gripping and rotating a work to be machined. A first machining tool performs a main machining of the work. A turret tool rest has an outer peripheral surface for holding a set of secondary tools along the outer peripheral surface thereof. The turret tool rest is selectively indexable to bring a selected secondary machining tool into a position to effect a secondary machining of the work and is selectively movable relative to the work to enable the selected secondary machining tool to perform the secondary machining of the work. The turret tool rest further includes a plurality of tool holders for holding a plurality of secondary tools. A back spindle is disposable on a side of the work opposite the main spindle for holding a selected secondary machining tool selected from the plurality of secondary tools. The back spindle is selectively movable to enable the selected secondary machining tool to perform the secondary machining of the work.
