Precision parts in the actual work of the strength and toughness requirements are relatively high, its performance and service life and its surface performance has a great connection, and the improvement of surface performance, can not simply rely on materials to do, is also very uneconomic practice, but the actual processing needs to make its performance meet the standard, at this time need to use surface treatment technology In recent years, this technology has been developed rapidly. In the field of mold surface treatment, mold polishing technology is a very important link, and also an important process in the process of workpiece processing. 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 technological process and polishing equipment, but also by the specularity of the part materials, which has not been paid enough attention in the current processing, which also means that the polishing itself is affected by the materials. Although the processing technology to improve the surface properties of precision parts is constantly upgraded, the most widely used technology in precision parts processing is hardening film deposition, nitriding and carburizing.
Because the nitriding technology can obtain a high level of surface properties, and the nitriding technology process has a very high consistency with the quenching process of steel in precision parts, and the nitriding temperature is very low, so after the nitriding technology treatment, there is no need for intense cooling process, so the deformation of precision parts will be very small, so the nitriding technology is the same It is one of the earliest technologies used to strengthen the surface properties of precision parts, and it is also the most widely used technology at present.
