Surface treatment of precision parts
It is worth reminding that the surface polishing process of precision parts is not only affected by the process steps and polishing equipment, but also affected by the mirror surface of the parts. This is not enough in the current processing. The emphasis is also on the fact that the polishing itself is affected by the material. Although the processing technology for improving the surface performance of precision parts is constantly being upgraded and upgraded, the most widely used in the processing of precision parts is mainly the deposition of hardened film, and the nitriding and carburizing technologies.
Because nitriding technology can achieve very high level of surface properties, and the process of nitriding technology has a very high consistency with the quenching process of steel in precision parts, and the nitriding temperature is very low, so that after osmosis Nitrogen technology does not require a violent cooling process, so the deformation of precision parts is very small. Therefore, nitriding technology is one of the earliest technologies used to strengthen surface properties in the processing of precision parts. The most extensive.
