In the processing of precision machinery parts, the requirements for strength and toughness are relatively high. 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, and it is also a very uneconomical approach. However, in actual processing, its performance must meet the standard. At this Време е необходима технология за обработка на повърхността .
In the field of mold surface treatment, mold polishing technology is a very important link and an important process in the processing of workpieces. The surface treatment process of precision machinery parts processing is very important in the processing process. It is worth reminding that the surface polishing of precision parts molds is not only affected by the process and polishing equipment, but also by the mirror surface of the parts material. This Point не е получил достатъчно внимание в текущата обработка, което също показва, че самото полиране е засегнато от материала .
Although the processing technology for improving the surface performance of precision parts is constantly innovating and upgrading, the most widely used in the processing of precision parts is still hardening film deposition, nitriding, and carburizing technology. Because nitriding technology can obtain a very high level of surface performance, and the process of nitriding technology has a very high℃of coordination and consistency with the quenching process of steel in precision части .
Температурата на азотирането е много ниска, така че не е необходим интензивен процес на охлаждане след лечение с азотиране, така че деформацията на прецизните части ще бъде много малка . Следователно технологията на азотността е една от най -ранните технологии, използвани за подобряване на повърхностните свойства на прецизните механични части, и е и най -широко използваната технология при настоящите .
