Surface treatment technology of precision parts

Precision parts have higher requirements on strength and toughness in actual work. Its working performance and service life are closely related to its surface performance, while the improvement of surface performance, it is impossible to rely solely on materials and is also a very uneconomical method. However, in actual processing, its performance must reach the standard. At this time, surface treatment technology is needed, this often achieves twice the result with half the effort, and this technology has also developed rapidly in recent years. In the field of mold surface treatment, mold polishing technology is a very important link and an important process in the process of workpiece processing. The surface treatment process of precision parts is very important in the processing process, so what are the surface treatment processes of precision parts? 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 by the specular degree of the part material, this point has not received enough attention in the current processing, which also shows that polishing itself is affected by materials. Although the processing technology to improve the surface performance of precision parts has been continuously innovated and upgraded, the most widely used technologies in the processing of precision parts are mainly hardened film deposition, nitriding and carburizing. Because nitriding technology can obtain a high level of surface performance, and the process of nitriding technology has a very high coordination and consistency with the quenching process of steel in precision parts, and the nitriding temperature is very low, in this way, intense cooling process is not required after nitriding technology treatment, so the deformation of precision parts will be very small, therefore, nitriding technology is also one of the earliest technologies used to strengthen surface properties in precision parts processing, and is also the most widely used at present.
