What are the processes for surface treatment of precision parts?

Source:

The requirements of strength and toughness are higher in the actual work. The performance and service life of the precision parts are closely related to the surface performance, and the improvement of the surface performance can not be done solely on material, but also very uneconomical. However, the performance must be made to reach the standard in the actual processing. Surface treatment technology is needed at this time, which can achieve twice the result with half the effort. In recent years, this technology has also been rapidly developed. Mold polishing technology is very important 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 parts is very important in the process of machining. What are the surface treatment processes of precision parts?


It is worth reminding that the polishing of the mold surface with the precision parts is not only affected by the process and the polishing equipment, but also influenced by the mirror degree of the part material. This point is not paid enough attention in the present processing. It is also said that the polishing itself is affected by the material. . Although the processing technology for improving the surface performance of precision parts is constantly upgrading and upgrading, the most used in the processing of precision parts is the deposition of the hardened film, and the nitriding and carburizing technology.


Because the nitriding technology can obtain very high surface performance, and the nitriding technology has a very high consistency with the quenching process of the steel in the precision parts, and the temperature of the nitriding is very low, so that the cooling process is not required after the nitriding technology is treated, so the precision parts are not required. The deformation will be very small, so nitriding technology is also one of the earliest technologies used to strengthen the surface performance in precision parts processing, and is also the most widely used.
