    • PROBLEM TO BE SOLVED: To provide a numerically controlled lathe with a guide bush capable of processing a work with high accuracy without need of a support device, such as an auxiliary guide. SOLUTION: In this numerically controlled lathe 100 having a headstock 110 which rotatably supports a main spindle 120, the guide bush 170 which is provided facing the headstock 110 and supports one edge of the rod-shaped work W extended from the main spindle 120, and a tool post 130 which has a tool T1 for processing the work W supported by the main spindle 120 and the guide bush 170, the first process range A which can move in the same direction as an axial line C of the main spindle, and processes the work W with the tool T1 attached to the tool post 130 is provided between the guide bush 170 and the main spindle 120 in the guide bush 170.
