PURPOSE: To improve machining ability, precision, and operability by adding a specified automatic machining function to an ordinary lathe, based on the ordinary lathe.
CONSTITUTION: A lathe is designed to move a tool rest 22 in the directions of a Z-axis, and an X-axis by driving a ball screw with the aid of a servo motor 18. The tool rest 22 is moved through one of manual movement wherein the tool rest is moved through rotation operation of a manual pulse generator for the Z-axis and the X-axis, manual operation wherein the tool rest is moved under a given machining condition along a preset route through tilting operation of feed levers 48 and 50, and automatic operation wherein the tool rest is moved under a given machining condition along a preset route between a preset starting point and a terminal point through tilting operation of an automatic operation starting lever 54.
