In the processing of precision machinery parts, the requirements for strength and toughness are relatively high. Its working performance and service life are closely related to its surface performance. The improvement of surface performance cannot be achieved simply by relying on materials, and it is also a very uneconomical approach. However, in actual processing, its performance must meet the standard. At this time, surface treatment technology is needed.
In the field of mold surface treatment, mold polishing technology is a very important link and an important process in the processing of workpieces. The surface treatment process of precision machinery parts processing is very important in the processing process. It is worth reminding that the surface polishing of precision parts molds is not only affected by the process and polishing equipment, but also by the mirror surface of the parts material. This point has not received enough attention in the current processing, which also shows that polishing itself is affected by the material.
Although the processing technology for improving the surface performance of precision parts is constantly innovating and upgrading, the most widely used in the processing of precision parts is still hardening film deposition, nitriding, and carburizing technology. Because nitriding technology can obtain a very high level of surface performance, and the process of nitriding technology has a very high degree of coordination and consistency with the quenching process of steel in precision parts.
The temperature of nitriding is very low, so no intense cooling process is required after nitriding treatment, so the deformation of precision parts will be very small. Therefore, nitriding technology is one of the earliest technologies used to enhance the surface properties of precision mechanical parts, and it is also the most widely used technology at present.
