What is cnc machining of precision parts?

It is a kind of mechanical processing, which has relatively high requirements on production equipment and cnc processing technology. With the development of industrial automation, there are more and more classifications of precision cnc machining. , the direction is getting thinner and more professional; the precision machinery in the future will be more and more integrated, no longer the simple mechanical processing of the past, and the combination of it and high technology can play a better role, especially the digitalization of processing brought about a qualitative leap. Development will become the key science for future industry development;

Any kind of mechanical equipment is composed of many precision parts, each part plays its own role, and all parts need to be assembled. After different parts are processed, we can get more suitable parts, so in order to make these products better serve the qualifications, many people are indispensable for the important link of precision machining;

In order to ensure the machining accuracy of precision parts, it is recommended to carry out rough machining and precision machining separately, because in rough machining, the cutting amount is relatively large, the parts will be subjected to cutting force, the clamping force will be relatively large, and the heat generation will be relatively large. Mechanical parts The machined surface will have obvious work hardening, and there will be relatively large internal stress inside the part. If roughing and finishing are carried out continuously, the accuracy of the part after finishing will be lost due to the redistribution of stress;

In the process line of precision parts processing, a heat treatment process is often arranged. The location of the heat treatment process is arranged to improve the cutting performance of the metal, such as annealing, normalizing and quenching and tempering. Generally arranged before processing. The machining process of precision parts is very strict. Advance and retreat interlocking, dimensional accuracy can be grasped, which can reduce material loss and cost. If the part is the wrong size, it becomes scrap and the part can no longer be used.
