What Is Precision CNC Machining?

What is CNC machining of precision parts? It belongs to a kind of mechanical machining, and has relatively high requirements on production equipment and cnc machining technology. With the development of industrial automation, there are more and more classifications of precision CNC machining. , the direction is getting more and more refined and professional; the precision machinery in the future will be more and more integrated, no longer the simple machining of the past, and the combination of it and high technology can play a better role, especially the digitalization of machining brought 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 the parts need to be assembled. After machining different parts, we can get more suitable parts, so in order to make these products better serve the qualifications, there are many people in 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 during rough machining, the cutting amount is relatively large, the parts will be subjected to cutting force, the clamping force will be relatively large, the heat generation will be relatively large, and the mechanical parts will be The machined surface will have obvious work hardening, and there will be relatively large internal stress inside the part. If roughing and finishing are performed continuously, the precision of the finished part will be lost due to the redistribution of stress;

In the process line of precision parts machining, 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. Usually arranged before machining. The machining process of precision parts is very strict. Advance and retreat interlocking, dimensional accuracy can be grasped, material loss and cost can be reduced. If the part is the wrong size, it becomes scrap and the part can no longer be used.
