Description

Gear hobbing is a kind of processing by gear hobbing cutter and gear hobbing machine. Compared with other gear forming methods, the cost of gear hobbing is relatively cheap but maintains a certain degree of accuracy, so it has become the mainstream gear forming method. Common materials for hobbing cutters are high-speed steel and tungsten steel. Tungsten steel hobbing cutters can be used to process gears with high hardness, high ductility, and high toughness. The tool life is also longer than that of high-speed steel, thereby reducing the number of tool changes. Increase productivity.
