ABSTRACT:
An automatic lathe includes a pair of gang tool posts disposed on opposite sides of a headstock. The headstock has a main spindle and is movable axially of the main spindle, and the pair of gang tool posts are independently movable in respective two directions perpendicular to each other and perpendicular to the axial direction. Pitches between work tools on one of the gang tool posts differ from pitches between work tools on the other gang tool post such that when a free-end position of an arbitrary work tool of a first gang tool post is aligned with that of an arbitrary work tool of a second gang tool post, free-end positions of the other work tools of the first gang tool post mutually differ from those of the other work tools of the second gang tool post. To ensure simultaneous machining of the front face of one workpiece and the back face of another workpiece respectively using front and rear work tools, the front work tools are mounted on a rear headstock and the rear work tools are mounted on one of the pair of gang tool posts.
