CNC, as its name implies, is a method of controlling machine tool movement and machining process with computer digital control and digital information. It has a high-speed, reliable, multi-functional, intelligent and open structure. It is an intelligent all-purpose air energy numerical control device with development structure. It is also a measure of national technological development level and comprehensive national strength, As an important indicator of information technology modernization, it has played an inestimable role, especially in the fields of Air China, biology, medical treatment and high-tech industries, and also reflects the level of national strength. Therefore, improving this technology is an important way to improve the country's comprehensive national strength and status.

Therefore, in contrast, the traditional machining and manufacturing industry is not only inefficient, but also often has some uncontrollable factors, which makes our work far less than expected. The workload is large and the requirements for our technicians are high, so there will be some periodicity and work limitations. Therefore, the use of digital NC machining technology is particularly important, It not only has high work efficiency, but also can simply repeat and carry out some high-precision, human naked eye and unrealistic fine work.

CNC can be realized simply, accurately, quickly and efficiently. It can be completed perfectly under the condition of artificially changing G code and controlling programming language. Therefore, it seems that perfection can know that the cost and capital cost of CNC processing in our book are expensive compared with traditional machining, but perfection is worth having better. Perfection needs to be pursued in the future, Continue to develop perfect high-tech industries to better benefit us.
