In this paper, using computer numerical control machining technology to the maximum diameter of 400mm for the general transformation of the design of horizontal lathe. First of all, the transformation of the horizontal lathe tasks and functions carried out a careful analysis of needs, and secondly to determine the general horizontal lathe CNC overall transformation program, including the main drive system of the transformation program, installed automatic rotary tool, the installation of encoder thread program, the transformation of feed system and design. Finally, after calculating the cutting force, ball screw design, the gear and the calculation of torque on the screw, gear selection, etc., the detailed design of a horizontal feed system.Keywords CNC technology Transformation design Lateral feed Lathe
