With the rapid development of science and technology, society on the structure of mechanical products, performance, accuracy, efficiency and variety of requirements are increasingly high, the proportion of single-piece and small and medium-lot products is increasing. Traditional general-purpose, special machine tools and process equipment have not been well adapted to the requirements of high-quality, high-efficiency, diversified processing.
         CNC machine tools as a combination of electronic information technology and traditional machining technology, a combination of modern precision machinery, computers, communications, hydraulic pneumatic, optoelectronics and other multidisciplinary technology as a whole, effectively solving the complex, precise, small batch of variable parts processing problems, to meet the high quality, high efficiency and multi-species, small batch of flexible production requirements, to adapt to the needs of a variety of mechanical products rapidly updated It represents the trend and trend of today's machining technology.
