Gear Teeth Processing Technology And Grinding Level
The tooth profile processing of the gear ring gear is the core of the entire gear processing. There are many processes in gear processing, which all serve the tooth profile processing, and the purpose is to finally obtain gears that meet the accuracy requirements.
According to the processing principle, tooth shape can be divided into forming method and generation method. In addition, wire cutting and powder metallurgy are also used for gear processing in non-standard designs, among which powder metallurgy is more widely used for small gear processing.
The forming method is a method of cutting out the tooth surface with a forming tool that conforms to the shape of the tooth slot of the gear to be cut, such as tooth milling, tooth broaching and forming tooth grinding.

The choice of tooth profile processing scheme mainly depends on the accuracy level, structural shape, production type and production conditions of the gear. For gears with different accuracy levels, the commonly used tooth profile processing schemes are as follows:
Gears with precision below level 8: quenched and tempered gears can meet the requirements with gear hobbing or gear shaping. For hardened gears, a processing plan can be adopted: rolling (inserting) teeth, processing tooth ends, quenching, and correcting holes. However, the tooth profile machining accuracy before quenching should be improved by one level.

Level 6~7 precision gears: For hardened gears, you can use: rough hobbing, fine hobbing, tooth end machining, fine shaving, surface quenching, calibration reference, and tooth honing.

Gears with level 5 accuracy and above: generally adopt: rough hobbing, fine hobbing, tooth end processing, quenching, correction reference, rough grinding and fine grinding. Gear grinding is currently the processing method with the highest accuracy and the smallest surface roughness value in tooth shape processing. The highest accuracy can reach level 3-4.
