CNC precision machining requires relatively high strength and toughness in actual work. Its working performance and service life are closely related to its surface performance. The improvement of surface performance cannot be achieved simply by relying on materials. It is an economical method, but in actual processing, the performance must be up to the standard. At this time, surface treatment technology is needed, which can often achieve twice the result with half the effort. In recent years, this technology has also been developed rapidly. In the field of mold surface treatment, mold polishing technology is a very important link, and it is also an important process in the process of workpiece processing. The surface treatment process of cnc precision machining is very important in the processing process, so what are the surface treatment processes of cnc precision machining?
It is worth reminding that the surface polishing treatment of CNC precision machining is not only affected by the process and polishing equipment, but also by the mirror surface of the part material, which is not enough in the current processing This also shows that the polishing itself is affected by the material. Although the processing technology to improve the surface performance of precision parts is constantly being innovated and upgraded, the most widely used in CNC precision processing is mainly hardened film deposition, and nitriding and carburizing technologies.
Because nitriding technology can obtain a very high level of surface properties, and the process of nitriding technology is very consistent with the quenching process of steel in CNC precision machining, and the temperature of nitriding is very low, so after nitriding Nitrogen technology treatment does not require intense cooling process, so the deformation of CNC precision machining will be very small, so nitriding technology is also one of the earliest technologies used to strengthen surface properties during CNC precision machining, and it is also currently used the broadest.
