ABSTRACT:
An NC lathe performs various processing at the same time to a plurality of works. The NC lathe includes a first spindle and a second spindle, and a tool rest having tools for processing works. The tool rest is freely movable in the direction of Z1-axis and X1-axis. The second spindle is freely movable in the direction of X2-axis and Z2-axis. An NC unit controls the movement in the direction of the X1-axis and the Z1-axis of the tool rest, and controls the movement in the direction of the X2-axis and the Z2-axis of the second headstock. The NC unit superposes the movement in the direction of the X2-axis on the movement of the X1-axis of the tool rest. Furthermore, the movement of the Z2-axis is superposed on the movement in the direction of the Z1-axis of the tool rest.
