Gear hobbing machine and gear shaper are usually used for gear processing. Due to the convenience of adjustment and maintenance, large-scale production efficiency will be low. Subsequently, the recoating technology is generated after the hob and the slotting tool are ground, which can significantly improve the service time of the tool, reduce the number of tool changes and tool grinding time, and improve the efficiency.

　　In the process of gear cutting, the radial shaving technology has great advantages, including high efficiency, tooth profile design, and easy realization of tooth profile. In the process of heat treatment, carburizing and quenching can be used for gear processing to ensure its good mechanical properties. For products that no longer need gear grinding after heat treatment, stable, safe and reliable heat treatment equipment is also necessary for enterprises. In the process of grinding processing, gear processing is mainly to finish some data such as the inner hole, end face, and shaft outer diameter of the gear after heat treatment, so as to improve the working dimension accuracy and reduce the form and location tolerance.
