Surface treatment technology of precision mechanical parts processing

by:Yifeng Metal     2022-03-18

In the processing of precision mechanical 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. Short and long is often uneconomical, but in actual processing, its performance must be up to standard, and surface treatment technology is needed at this time.


In the field of mold surface treatment, mold polishing technology is a very important link, and it is also an important process in the processing of workpieces. The surface treatment process of precision mechanical parts is very important in the process of processing. It is worth reminding that the polishing of the mold surface of precision parts is not only affected by the process and polishing equipment, but also affected by The influence of the specularity of the part material has not been paid enough attention in the current processing, which also shows that the polishing itself is affected by the material.


Although the processing technology to improve the surface performance of precision parts is constantly innovating and upgrading, it is widely used in the processing of precision parts. The main ones are hard film deposition, and nitriding and carburizing technology. Because nitriding technology can obtain a 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.



The temperature of nitriding is short and long, so it does not need to be violently treated after nitriding technology. Therefore, the deformation of precision parts will be very small, so the nitriding technology is also one of the earliest technologies used to strengthen the surface performance in the processing of precision mechanical parts, and it is also widely used.
