The Y3150E hydraulic gear hobbing machine uses a gear hobbing cutter to roll and cut cylindrical spur gears, helical gears, and splines using the generative method. Suitable for single piece, small batch or batch production of gear processing. The main electrical and hydraulic components adopt well-known domestic manufacturers' brand products. The main key castings such as the bed and column adopt a double wall, high rib plate structure, which is compact, has strong dynamic and static stiffness, and high accuracy. The machine tool adopts a semi sealed protective cover in the working area, which does not leak oil and eliminates the pollution of the production environment caused by oil leakage during gear rolling. Special functional components can be selected according to user requirements. The machine tool has strong rigidity, stable working accuracy, and convenient operation. The machine tool can operate in either forward or backward milling mode. The machine tool is equipped with an automatic shutdown mechanism, safety device, and automatic lubrication system, in accordance with the standard GB/T8064-1998 "Accuracy Testing of Gear Hobbing Machines". According to the large or small module of the processed gear, it can be fed once or multiple times, and its precision machining can reach level 7 accuracy of GB/T10095-2001 "Precision of Involute Cylindrical Gears".
