Gear processing usually uses gear hobbing machines and gear shaping machines, which are convenient for adjustment and maintenance, and production efficiency will be low for large-scale production. Later, the production of re-coating technology after sharpening of hobs and inserting knives can significantly increase the use time of knives and reduce the number of tool changes and sharpening time. In the process of picking teeth, radial gear shaving technology has great advantages, including high efficiency, easy to realize the modification of the designed tooth profile and tooth direction.

In the heat treatment process, the gear requires carburizing and quenching to ensure its good mechanical properties. For products that no longer need to be ground after being heated, stable and reliable heat treatment equipment is also necessary. In the grinding process, it is mainly to finish the heat-treated gear inner hole, end face, shaft outer diameter and other parts to improve the dimensional accuracy and reduce the form and position tolerance.

Gear processing is mainly to control the accuracy of transmission between gears during operation, such as the smoothness of transmission, the fluctuation of instantaneous speed, if there is alternating reverse operation, whether the backlash of the tooth reaches the required range, and if there is an impact load , The accuracy should be slightly improved to reduce the damage to the gear caused by the impact load.
