Surface treatment process of precision mechanical parts processing

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 solely by materials, and it is also very uneconomical. However, in actual processing, its performance must reach the standard. At this time, surface treatment technology is needed.
Mold polishing technology is a very important link in the field of mold surface treatment, and it is also an important process in the process of workpiece processing. The surface treatment process of precision mechanical parts is very important in the processing process. It is worth reminding that the mold surface polishing of precision parts is not only affected by the process and polishing equipment, but also by the parts. The effect of the mirror surface of the 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 current processing technology to improve the surface performance of precision parts is constantly innovating and upgrading, the most commonly used in precision parts processing is mainly hard film deposition, nitriding and carburizing technologies. Because the nitriding technology can obtain a very high level of surface performance, and the process of the nitriding technology has a very high consistency with the quenching process of the steel in the precision parts.

The temperature of nitriding is very low, so after the nitriding technology is processed, there is no need for an intense cooling process, so the deformation of the precision parts will be very small, so the nitriding technology is also used in the processing of precision mechanical parts One of the earliest techniques used to enhance surface performance is currently widely used.
