Abstract
A compound lathe in which a headstock is horizontally movable along a spindle axis to provide longitudinal feeding of a workpiece mounted for rotation with the spindle and a saddle carrying a turret is vertically movable to provide transverse feeding. The saddle is slidably disposed on vertical guideways which is formed on a column mounted on a bed at the back of the headstock rearwardly of cutting areas of the workpiece and which vertically extends in a plane parallel to the axis of the spindle. The turret supports tools for turning, milling, drilling and other operations. Numerically controlled servo motors preferably position the headstock and saddle. A secondary workpiece gripping means is provided to grip the end of the workpiece opposite the headstock and is releasably connected to the headstock for movement therewith. The gripping means allows accurate secondary machining of the cut-off portion of a parted workpiece by the tools on the turret.
