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

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

(2) Milling machine milling: can process straight rack

(3) Inserting teeth: may Gear processing steps. 1process internal teeth

(4) chilly 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 Vacuum Pump 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 equipment finishing
