Surface treatment technology of precision parts

Precision parts in the actual work requirements for strength and toughness is higher, its working performance and service life and its performance has a great deal of contact surface, and improve the performance of surface, can not simply rely on material do, is also very uneconomical practice, but in the actual processing must make its performance up to standard, at this time will need to use the surface treatment technology, This often produces more results with less effort, and the technology has developed rapidly in recent years. In the field of mold surface treatment, mold polishing technology is a very important link, and it is also an important process in the process of workpiece processing. The surface treatment technology of precision parts is very important in the processing process, so what are the surface treatment technology of precision parts?

It is worth reminding that the surface polishing of the mold of precision parts is not only affected by the process and polishing equipment, but also by the mirror degree of the parts material. This point has not been paid enough attention in the current processing. It also shows that the polishing itself is affected by the material. Although the processing technology to improve the surface performance of precision parts continues to innovate and upgrade, but the most used in the processing of precision parts is mainly hardening film deposition, and nitriding, carburizing technology.

Because nitriding technology can obtain a high level of surface performance, and technology of nitriding process with precision parts of steel quenching process has a very high consistency, and nitriding temperature is very low, so after treated with nitriding technique does not require drastic cooling process, the deformation is very small, so the precision parts in Therefore, nitriding technology is one of the earliest technologies used to strengthen the surface performance in the processing of precision parts, and it is also the most widely used at present
