Precision parts require high strength and toughness in practical work, and their working performance and service life are closely related to their surface properties. The improvement of surface performance cannot be achieved solely through materials, and it is also very uneconomical. But in actual processing, its performance must meet the standards. At this point, surface treatment technology is needed, often achieving twice the result with half the effort. In recent years, this technology has also developed rapidly. Mold polishing technology is a very important step in the field of mold surface treatment and also an important process in the workpiece processing process. The surface treatment technology of precision parts is very important in the mechanical processing process, so what are the surface treatment technologies of precision parts?

It is worth reminding that the polishing treatment of the surface of precision part molds is not only affected by the process and polishing equipment, but also by the mirror degree of the part material. This has not received sufficient attention in current processing, which also indicates that polishing itself is influenced by the material. Although the processing techniques for improving the surface performance of precision parts are constantly innovating and upgrading, the most widely used technologies in precision parts processing are hardening film deposition, nitriding, and carburizing.

Due to the high level of surface performance that nitriding technology can achieve, and the high consistency between nitriding technology and the quenching process of steel in precision parts, the nitriding temperature is very low, so there is no need for intense cooling process after nitriding technology, so the deformation of precision parts will be very small. Therefore, nitriding technology is also one of the early technologies used in precision parts processing to strengthen surface performance.
