Surface treatment technology of CNC machining

In the field of precision CNC machining, the working performance and service life of parts with high requirements for strength and toughness are closely related to their surface properties. However, the improvement of surface treatment performance can not be achieved simply by relying on materials, which is also very uneconomic. However, in the actual processing, its performance must meet the standard. At this time, surface treatment technology is needed . Let’s take a look at the surface treatment process of CNC machining

1. Hardware mold industry, CNC processing of mold accessories, process polishing technology is a very important link, but also an important process in the process of workpiece processing. The surface treatment process of precision mechanical parts is very important in the process of processing. 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 affected by the specularity of the parts. This point has not been paid enough attention in the current processing, which also shows that the polishing place is very important The process itself is affected by the material.
2. Precision CNC machining. At present, the machining technology to improve the surface properties of precision parts is constantly upgraded. However, the main applications in the machining of precision CNC parts are hardening film deposition, nitriding and carburizing technology. Because the nitriding technology can obtain a high level of surface properties, and the nitriding technology process has a very high consistency with the quenching process of steel in precision parts.
3. Surface treatment details. 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 machined parts will be very small. Therefore, nitriding technology is also one of the early technologies used to strengthen the surface properties of precision mechanical parts, which is widely used at present.
