Gear hobbing and gear hobbing each have their own characteristics:Gear hobbing. Its characteristics include: using the principle of generation method, it can achieve tooth profile accuracy of 8 to 7 levels; Use hobs with the same module to process gears with different teeth, reduce the number of tools, improve accuracy and reduce costs; Suitable for processing spur gears, helical gears, and worm gears, etc; Belongs to continuous cutting, with high accuracy and productivity; Not suitable for machining internal gears and multiple gears that are too close together; Suitable for single piece small batch production and mass production in batches

Gear shaping processing. Its characteristics include: using the principle of generation method, the selection of cutting tools only requires the same modulus and pressure angle as the gear being cut, regardless of the number of teeth, saving tool costs; The machining accuracy is similar to that of gear hobbing, but the surface roughness is slightly lower; The manufacturing and inspection of insert cutters are simpler than rolling cutters, making it easier to control tool accuracy. However, their transmission chains are more complex, resulting in accumulated transmission errors and slightly lower gear division accuracy than rolling cutters; When inserting gears, the return stroke of reciprocating motion is an empty stroke, so the productivity is not as high as that of rolling gears; Suitable for processing spur gears, internal gears, double or multiple gears; Suitable for single piece small batch production and mass production in batches.
