How is the gear machined?

Gear machining is divided into two main methods in principle:

1. The copying method is to use a disk milling cutter or a finger milling cutter with the same shape as the gear tooth slot to process on a milling machine.

2. Generating method is also called generating method, which uses the meshing principle of gears to cut the tooth profile of gears. This method has high precision in gear machining and is the main method of gear machining at present. There are many generating methods, such as gear shaping, gear hobbing, gear shaving and gear grinding, among which gear shaping and gear hobbing are the most commonly used, while gear shaving and gear grinding are used in occasions with high precision and smoothness.
