The machining of the gear needs to provide the most elementary modulus m, the number of gears Z, 
and the pressure angle a. Gear Speed reducer thickness h.
Gear processing strategies generally include hobbing, gear shaping, and milling gears, in addition to grinding teeth with high precision requirements. Corresponding machines and knives have hobbing and hobbing cutters, gear shaping machines and gear shaping knives, horizontal milling devices and gear milling cutters, equipment grinding machines and gear grinding wheels. details as follows:
(1) Hobbing machine hobbing: It can process helical tooth 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 tooth: can process cheap pinions in large quantities
(7) Grinding machine grinding teeth: can process gears on precision machine
(8) Die casting machine casting tooth: most processing non-ferrous metal gears
(9) Shaving machine: It really is some sort of metal cutting for gear finishing
