ABSTRACT:
A numerically controlled lathe which is capable of effecting combined machining comprises a frame constituting the main body, a main spindle driven to rotate, a main spindle chuck provided on the main spindle to hold a workpiece, a multiple-tool head having a plurality of tools, a turret head and a rear machining head. The multiple-tool head has three servomotors to move it along three axes which are perpendicular to each other. The body of the multiple-tool head has an annular frame structure. At least two rows of rotary and non-rotary tools for machining the workpiece are disposed on the multiple-tool head body in a direction parallel with one of the directions of movement. A tool driving motor is provided on the multiple-tool head body to drive the rotary tools. The rotary tools include a polygon machining tool for machining a polygonal workpiece. The multiple-tool head, the turret head and the rear machining head effect machining simultaneously or successively.
