Document Type and Number:
Japanese Patent JP4677062
Kind Code:
B2
Abstract:
A NC lathe which can perform various processing at the same time to a plurality of works is provided. The NC lathe of the present invention includes a first spindle 121 and a second spindle 131, and a tool rest 160 having tools T1, T2 for processing works W1, W2 held by these. The tool rest 160 is freely movable in the direction of the Z1-axis and the X1-axis. The second spindle 131 is freely movable in the direction of the X2-axis and the Z2-axis. A NC unit 190 controls the movement in the direction of the X1-axis and the Z1-axis of the tool rest 160, and controls the movement in the direction of the X2-axis and the Z2-axis of the second headstock 130. The NC unit 190 makes it possible to superpose the movement in the direction of the X2-axis necessary for processing the work W2 by the second tool T2 on the movement in the direction of the X1-axis of the tool rest 160. Furthermore, the movement in the direction of the Z2-axis necessary for processing the work W2 by the second tool T2 is superposed on the movement in the direction of the Z1-axis of the tool rest 160.
