With the continuous development of science and technology, the community has increasingly stronger demands for product diversification, product upgrading Panda faster, multi-species, a marked increase in the proportion of small and medium volume production, complex-shaped parts, more and more the more precision to the higher. In addition, the intense competition in the market demands shorter and shorter product development cycle, the traditional processing equipment and manufacturing methods are difficult to adapt to this diversity, flexible high-performance parts with complex shapes, high-quality processing requirements. Thus, in recent decades, can effectively solve the complex, sophisticated, small batch processing problems and ever-changing parts CNC machining technology has been rapid development and wide application of Manufacturing technology to make fundamental changes have taken place.
