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 can not be achieved solely by relying on materials, which is also a very uneconomical approach. However, in actual processing, its performance must be up to the standard. At this time, surface treatment technology is needed.
In the field of mold surface treatment, mold polishing technology is a very important link, and also an important process in the process of workpiece processing. The machining surface treatment process of precision mechanical parts is very important in the machining process. It is worth reminding that the mold surface polishing process of precision parts is not only affected by the process and polishing equipment, but also by the specularity of part materials. This point has not been paid enough attention in the current machining, which also shows that polishing itself is affected by materials.
Although the processing technology to improve the surface performance of precision parts is constantly upgraded, the hardening film deposition, nitriding and carburizing technology are still widely 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 nitriding temperature is very low, so after being processed by nitriding technology, there is no need for intense cooling process, so the deformation of precision parts will be very small. Therefore, nitriding technology is also one of the earliest technologies used to strengthen surface performance in the processing of precision mechanical parts, and is widely used at present.
