The machining of the apparatus needs to supply 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, and also grinding teeth with high precision requirements. Corresponding devices and knives possess hobbing and hobbing cutters, gear shaping machines and equipment shaping knives, horizontal milling devices and equipment milling cutters, gear grinding machines and gear grinding wheels. details as follows:

(1) Hobbing Speed Gearboxes machine hobbing: It can 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: could be processed without debris

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

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

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

(8) Die casting machine casting teeth: most processing nonferrous metal gears

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