There are two kinds of involute gear processing methods. One is profiling method, which uses shaped milling cutter to mill the gear slot, "imitating the shape". The other is the model method (expansion method).
(1) Gear hobbing machine: it can process helical gears of less than 8 modules
(2) Milling machine: straight rack can be processed
(3) Gear slotting machine: can process internal gear
(4) Toothing of cold beating machine: chip free processing
(5) Gear shaper: can process 16 module big gear
(6) Precision gear casting: it can process cheap small gears in large quantities
(7) Gear grinding machine: it can process gears on precision machine tool
(8) Die casting machine teeth: most non-ferrous metal gears are processed
(9) Gear shaving machine: It is a metal cutting machine for gear finishing
