Surface treatment technology of precision parts

Precision parts require high strength and toughness in actual work. Their working performance and service life are closely related to their surface properties. However, the improvement of surface properties cannot be achieved by simply relying on materials, which is also very uneconomical. However, in actual processing, their performance must meet the standard. At this time, surface treatment technology is needed, which can often achieve twice the result with half the effort, In recent years, this technology has also developed rapidly. In the field of mold surface treatment, mold polishing technology is a very important link, and it is also an important process in the process of workpiece processing. The surface treatment process of precision parts is very important in the machining process. What are the surface treatment processes of precision parts?

It is worth reminding that the mold surface polishing of precision parts is not only affected by the process and polishing equipment, but also by the specularity of the part material. This has not been paid enough attention in the current processing, which also shows that the polishing itself is affected by the material. Although the machining technology to improve the surface performance of precision parts has been continuously innovated and upgraded, the most widely used technologies in precision parts machining are hardening film deposition, nitriding and carburizing.

Because the nitriding technology can obtain a very high level of surface performance, and the nitriding technology process is very consistent with the quenching process of steel in precision parts, and the nitriding temperature is very low, so there is no need for intense cooling process after nitriding technology treatment, so the deformation of precision parts will be very small, Therefore, nitriding technology is also one of the earliest technologies used to strengthen surface properties in precision parts processing, and it is also the most widely used at present.
