[0002] Gear hobbing machine is the most widely used machine tool in gear processing. It is mainly used to process spur / helical cylindrical gear wheels with a module of m2.5mm, and can realize special processing such as axial drum gears, splines, worm wheels, sprockets, splines, etc. When using high-precision carbide hobs (AA grade) and reasonable cutting specifications, it can process workpieces such as spur cylindrical gears and helical gears with a diameter of ≤100mm. The machine tool has strong overall rigidity, stable working accuracy, and easy operation. It can process soft tooth surface gears and hard tooth surface gears.

[0003] In the existing equipment, cooling pipes are installed inside the cutting teeth to provide water flow to absorb heat energy, thereby absorbing the temperature generated by the entire cutting teeth, and then the water that absorbs a large amount of heat energy is cooled through the cooling system to form a circulating cooling system, thereby improving the machining accuracy of the gears.
