What Are The Processing Methods Of Gear Racks?

The processing of racks and pinions usually adopts the cutting method. The cutting method of wheel teeth can be divided into two categories: profiling method and model forming method.

1. Profiling method
The profiling method is processed on a milling machine with a disc milling cutter or finger milling cutter with the same shape as the gear cogging.

2. Fan Chengfa
The Fan Cheng method is also called the Zhancheng method, which uses the meshing principle of the gear to cut the tooth profile of the wheel teeth. This method has high precision in processing gears and is the main method of gear tooth processing at present. There are many types of Fan Chengfa, including shaping, hobbing, shaving, grinding, etc., among which shaping and hobbing are commonly used
