In mechanical processing, the requirements for strength and toughness are relatively high. Its working performance and service life have a great relationship with its appearance performance. The improvement of appearance performance cannot be achieved solely by relying on materials, and it is also very uneconomical. However, in practice, it is necessary to make the performance reach the specification. At this time, the surface treatment technology needs to be used.
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 and disposal. The surface treatment process of mechanical processing is very important in the processing process. It is worth reminding that the surface polishing of the mold is not only affected by the process and polishing equipment, but also by the mirror surface of the part data. This point has not been paid enough attention in today's processing, which also clarifies that polishing itself is affected by materials.
Although today's processing technology to improve the appearance of parts is upgraded and upgraded from time to time, the more commonly used in processing are hardened film accumulation, nitriding and carburizing technologies. Because the nitriding technology can achieve a very high level of appearance performance, and the process of the nitriding technology has a very high harmony with the quenching process of China Steel.
The temperature of nitriding is very low, so that after the nitriding technology is processed, there is no need for a violent cooling process, so the deformation will be very small. Therefore, the nitriding technology is also used to strengthen the appearance during mechanical processing. One is also widely used at present.
