Forming method of gear machining

1. The forming method of gear processing, mainly milling teeth and pulling teeth:

(1) Fine cast teeth: cheap pinion gears can be processed in large quantities;

(2) die casting machine casting teeth: most of the processing of non-ferrous metal gear;

(3) milling machine milling gear: can process straight rack;

(4) Gear grinding machine: it can process the gears on the fine mother machine;

(5) Cold beating machine tooth: can be processed without chips;

2. Gear processing into the law, mainly hobbing gear:

(1) Hobbing machine: it can process helical teeth below 8 modulus;

(1) Spatter: can process internal teeth;

(2) Shaving machine: It is a kind of metal cutting for gear finishing.

(3) gear planer gear planer: can process 16 modulus large gear;

The main differences between the two methods are:

1. The forming method has relatively low processing accuracy, and the generating method has relatively high processing accuracy up to 3 levels;

2. The production efficiency of the forming method is relatively high; the production efficiency of the developing method is relatively low;

3. The development method requires grinding gear equipment, and the generation cost is relatively high.
