Involute feed machinery gear processing method has two categories, one is the profiling method, using a milling cutter alveolar molding gear, is "imitation-shaped". Another is generating method (generating method).
(1) hobbing machine hobbing: 8 module can be processed less inclined tooth
(2) milling milling: rack can be processed straight
(3) slotting slotting: can be processed within a tooth
(4) cold fight machine to fight tooth: You can Chipless working
(5) gear planing machine planing teeth: 16 module can process the large gear
(6) precision casting teeth: can process large quantities of cheap pinion
(7) grinding machine grinding teeth: Gear can be processed on precision machine tools
(8) Die Casting Machine cast tooth: Most non-ferrous metal processing gear
(9) feed mechanical gear shaving machine: a gear with a finishing of metal cutting machine tools
