CNC machine tools in China is less than the rate of 5%, CNC technology in terms of the level and rate of NC machine tools are lagging far behind developed countries in the West. Speed up the transformation of the development of China's machine tool industry, has important practical significance and value. This paper mainly using computer numerical control technology to alter the ordinary horizontal lathe whose maximum machining diameter is 400mm. first of all, horizontal lathe for ordinary tasks and functions of the transformation of a careful analysis of needs,Second, the design of the overall reform program, including the main drive system, feed system, rotary tool holder and the program of microcomputer control system design, after the final calculation of cutting force, ball screw, gear and stepper motor selection, vertical feed is given for the detailed design.
