The Y3150 is a high-performance heavy-duty gear hobbing machine, designed for precision cutting of spur gears, helical gears, worm gears, and spline shafts. With a maximum workpiece diameter of 550mm and module capacity up to 8mm, it meets the production needs of various industrial gears in machinery manufacturing, automotive, reducers, and engineering equipment industries.

The machine adopts a robust cast iron bed structure, ensuring excellent rigidity and stability during heavy cutting. The tool spindle uses Morse No.5 taper and supports hob arbors of Φ22, Φ27, and Φ32mm, with a maximum installed tool size of 160*160mm. The spindle has 9 adjustable speeds ranging from 40-250rpm, and the axial feed offers 12 steps from 0.4-4mm/r, adapting to different gear materials and cutting processes.

The worktable has a diameter of 520mm and a maximum rotation speed of 15.6r/min, with hydraulic rapid travel up to 50mm. The tool post features a vertical travel of 300mm and a maximum rotation angle of 240°, providing flexible machining ranges for different gear parameters. The machine is equipped with a 4kW main motor, 1.1kW axial rapid motor, 1.1kW hydraulic pump motor, and 0.55kW worktable rapid motor, ensuring stable power output for continuous production.

With compact overall dimensions (244*137*180cm) and a net weight of 4500kg, the Y3150 delivers reliable performance and long service life. It is widely used for gear processing in gearboxes, reducers, motors, and mechanical transmission parts, providing an efficient solution for industrial gear manufacturing.

1. Install the machine on a reinforced concrete foundation with sufficient load-bearing capacity to support the 4500kg weight and ensure stable operation.
2. Connect to a standard three-phase power supply with reliable grounding to ensure electrical safety for all motors.
3. Before each operation, check the lubrication system, hydraulic oil level, and coolant system to ensure normal running.
4. Confirm workpiece clamping, tool installation, and program parameters before starting automatic gear cutting to prevent collisions.
5. Keep hands and foreign objects away from the rotating worktable, tool spindle, and moving parts during operation.
6. Adjust spindle speed and feed rate according to the gear module and material hardness to protect the hob and ensure machining quality.
7. Regularly clean iron chips, guide rails, and transmission parts, and replace lubricating oil and hydraulic oil as required.
8. When the machine is idle for a long time, turn off the main power, clean all surfaces, and apply anti-rust treatment to metal parts.
