Processing on the quality of the product quality of machinery play a decisive role. If a product in the processing time for the lack of reasonable directly affect the quality of the products. At the same time the productivity of products will also be greatly restricted, so processing technology for the impact of mechanical products is self-evident, Especially for high precision machining of parts, equipment and advanced technology are not very important Machine tools by some combination of common parts and components for the design in order to make the combination of machine tools meet the expected performance requirements. Have to be configured on the uniform and reasonable, in line with the spirit of commerical and convenience, it must be designed by a combination of various machine components of the relationship between a comprehensive analysis and study. In particular the important steps are the determination of a high degree of loading machine , universal machine parts choice
