Involute gear processing methods have 2 types, one is a profiling method, form milling cutter milling grooves of the gears, is the "imitation". Another is generating (generating).
(1) gear-hobbing machine gear hobbing: 8 modules can be processed here helical gear
(2) the milling machine milling: machining straight-tooth
(3) the slotting Shaper: processing gear
(4) gear cold machine: chipless machining
(5) the planing machine gear Shaper: processing 16 modulus gears
(6) precision cast on: high volume processing cheap gear
(7) grinding machine grinding: on the processing of precision machine tools gear
(8) the die casting machines casting gear: most machining Nonferrous Metal Gear
(9) shaving machine: is a precision processing of metal-cutting machine tools
