PURPOSE: A double spindle gang type CNC(Computer Numerical Control) lathe is provided that gang sliders are arranged the Y-axis, it is carried to the top and bottom, the tool of many numbers installs, and the quick machining cycle time is guaranteed. CONSTITUTION: A double spindle gang type CNC lathe comprises a bed unit(10), a main spindle unit(20), a sub spindle unit(30), a tool hole unit(40), and a moving unit(50). Gripping the processed product and the main spindle unit rotates. The main spindle unit reciprocates in a direction of a Z-axis parallel to a rotational axis of the processed product. The sub spindle unit is installed in the bed unit in order to face with the main spindle unit. It grips the processed product and the sub spindle unit rotates. It moves the Z-axis. A plurality of tools installs to the tool hole unit. The tool hole unit moves between the main and the sub spindle units the Y-axis. The moving unit supports the tool hole unit. The tool hole unit is reciprocated the X-axis.
