And machinery manufacturing scale and level of development, economic strength and scientific and technological level of response is one of the important signs. Improve processing efficiency, reduce production costs, improve processing quality and rapid updating products, machinery manufacturing and development on the basis of competition, machinery manufacturing technology is a symbol. First in the early 1950s, the 20th century a CNC machine tool, mechanical and electrical integration is a typical CNC machine tool products, integrated precision machinery, electronics, electric traction, automatic control, automatic detection, fault diagnosis, and computer technology in such areas. High-precision CNC machine tool. high efficiency and high flexible decision is vigorously promoting the use of CNC machine tool manufacturers to increase manufacturing capacity, improve their ability to adapt and competitive ability. CNC milling machining is the most commonly used method of NC and the main one, since the accession to the WTO. Ch
