Precision parts have relatively high requirements on strength and toughness in actual work, and their working performance and service life are closely related to their surface properties. It is an economical method, but in actual processing, its performance must meet the standard. At this time, surface treatment technology is required, which can often achieve twice the result with half the effort. In recent years, this technology has also been developed rapidly. Mold polishing technology is a very important link in the field of mold surface treatment, and it is also an important process in the processing of workpieces. The surface treatment process of precision parts is very important in the processing process, so what are the surface treatment processes of precision parts?

It is worth reminding that the polishing of the mold surface of precision parts is not only affected by the process and polishing equipment, but also by the mirror surface of the part material, which is not enough in the current processing. The importance of this also shows that the polishing itself is affected by the material. Although the processing technology to improve the surface performance of precision parts is constantly innovating and upgrading, the most widely used in the processing of precision parts are mainly hardened film deposition, nitriding and carburizing technology.

Because the nitriding technology can obtain a high level of surface properties, and the nitriding technology has a very high coordination and consistency with the quenching process of the steel in the precision parts, and the nitriding temperature is very low, so after the nitriding process Nitrogen technology does not require intense cooling process after treatment, so the deformation of precision parts will be very small, so nitriding technology is also one of the earliest technologies used to strengthen surface properties in precision parts processing, and it is also currently used. the most extensive.
