Inner gear grinding parts

1. Product name: Inner gear grinding parts  Gear shaped supr pinion
2. Production process: forging +normalizing+rough machining+modulation+finish machining
3. Material: 42CrMo alloy steel
4. Description: This Inner gear grinding parts is produced by using closed die forging method to acquire a high forging ratio, usually »1:5. ThenInner gear grinding parts are normalized to remove residue stress of forging, and to achieve a better even inner microstructure.  The following step is heat treatment, to get required mechanical property values. 
5. Advantage: Strict process control, high quality.
