Abstract
There is provided a numerically controlled lathe capable of simultaneously performing various kinds of machining to a plurality of workpieces.An NC lathe according to the present invention has a first main shaft 121 and a second main shaft, a first tool rest 160 to which a tool T1 and/or a tool T2 used to machine workpieces W1 and W2 grasped by these main shafts are attached, and a second tool rest 180 to which a tool T3 and/or a tool T4 used to machine the workpieces W1 and W2 are attached. The first tool rest 160, the second tool rest 180 and the second head stock 130 can move in the direction of a Z axis and the direction of an X axis without restraint. A numerical control device 191 controls movement of the first tool rest 160, the second tool rest 180 and the second head stock 130 in the direction of the X axis and movement of the same in the direction of the Z axis. As a result, a plurality of types of machining can be simultaneously applied to the two workpieces by using at least three tools in the tools T1 to T4.
