The machining of the gear needs to provide the most basic modulus m, the number of gears Z, and the pressure angle a. Gear thickness h.

Gear processing methods generally include hobbing, gear shaping, and milling gears, as well as grinding teeth with high precision requirements. Corresponding machines and knives have hobbing and hobbing cutters, gear shaping machines and gear shaping knives, horizontal milling machines and gear milling cutters, gear grinding machines and gear grinding wheels. details as follows:

(1) Hobbing machine hobbing: It can process helical teeth below 8 modules

(2) Milling machine milling: can process straight rack

(3) Inserting teeth: can process internal teeth

(4) cold punching machine: can be processed without debris

(5) planing machine planing teeth: can process 16 modulus large gears

(6) Precision casting teeth: can process cheap pinions in large quantities

(7) Grinding machine grinding teeth: can process gears on precision machine

(8) Die casting machine casting teeth: most processing non-ferrous metal gears

(9) Shaving machine: It is a kind of metal cutting for gear finishing
