There are two main types of machining methods for involute gears. One is the profiling method, which uses a forming milling cutter to mill out the grooves of the gears, which is "imitating the shape".
The other is the modular method (expansion method).
(1) Gear hobbing machine for gear hobbing: capable of processing helical teeth with a modulus of less than 8
(2) Milling machine for tooth milling: capable of processing straight gear racks
(3) Slotting machine teeth: capable of machining internal teeth
(4) Cold tapping machine teeth: can be processed without chips
(5) Gear planer: capable of processing 16 module large gears
(6) Precision gear casting: capable of processing low-cost small gears in large quantities
(7) Gear grinding machine: capable of machining gears on precision mother machines
(8) Die casting machine teeth casting: Most processed non-ferrous metal gears
(9) Gear shaving machine: It is a metal cutting machine tool used for gear precision machining
