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, equipment shaping, and milling gears, along with grinding teeth with high precision requirements. Corresponding devices and knives possess hobbing and hobbing cutters, gear shaping machines and gear shaping knives, horizontal milling machines 
and equipment milling cutters, equipment grinding machines and equipment grinding wheels. details the following:
(1) Hobbing machine hobbing: It could Cast Iron process helical tooth below 8 modules
(2) Milling machine milling: can process straight rack
(3) Inserting teeth: may process internal teeth
(4) frosty punching machine: can be processed without debris
(5) planing machine planing teeth: can process 16 modulus large gears
(6) Precision casting tooth: can process cheap pinions in large quantities
(7) Grinding machine grinding teeth: can procedure gears on precision machine
(8) Die casting machine casting tooth: most processing non-ferrous metal gears
(9) Shaving machine: It really is a kind of metal cutting for equipment finishing
