Surface treatment process of precision mechanical parts processing
Precision mechanical parts processing, the strength and toughness requirement is higher, its working performance and service life with its surface performance, and surface performance, is not simply rely on material, is also very uneconomic, but the actual processing must make its performance to the standard, this time need to use the surface treatment technology.
In the field of mold surface treatment, mold polishing technology is a very important link, but also an important process in the process of workpiece processing. Precision mechanical parts processing surface processing process is very important in the processing process, it is worth reminding that precision parts mold surface polishing work, not only received the process and polishing equipment, but also be affected by the parts of material mirror, this in the processing did not get enough attention, this also shows that polishing itself is affected by the material.
Although the processing technology to improve the surface performance of precision parts is constantly innovated and upgraded, the most common applications in the processing of precision parts are mainly hardening film deposition, and nitrogen infiltration and carburization technology. Because the nitriding technology can achieve a high level of surface performance, and the nitriding technology and precision parts of the steel quenching process has a very high coordination.
The temperature of nitriding is very low, so the intense cooling process is not needed after the nitriding technology treatment, so the deformation of the precision parts will be very small. Therefore, the nitriding technology is also one of the early technologies used to strengthen the surface performance in the processing of precision mechanical parts, and it is also widely used at present.
