Surface treatment process of precision machinery 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.

However, the improvement of surface performance cannot be achieved simply by relying on materials, and it is also very uneconomical. However, in actual processing, the 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 process of workpiece processing. The surface treatment process of precision mechanical parts processing is very important in the processing process.

It is worth reminding that the mold surface polishing treatment of precision parts is not only affected by the process and polishing equipment, but also by the parts The influence of material specularity 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 being innovated and upgraded, the hardened film deposition, and nitriding and carburizing technologies are mostly used in the processing of precision parts. Because nitriding technology can obtain a high level of surface properties, and the process of nitriding technology is very consistent with the quenching process of steel in precision parts.

The temperature of nitriding is very low, so there is no need for intense cooling process after nitriding technology treatment, so the deformation of precision parts will be very small, so nitriding technology is also used to strengthen precision mechanical parts Surface properties are one of the earliest technologies and are currently the most widely used.
