CNC High Speed Dry Cutting Gear Hobbing Machine 

GHE-260CNC6    GHE-260CNC7

Machine Summary
The model GHE-260CNC6 high speed & dry cutting CNC gear hobbing machine is of 6 axes one with 4 axes coordinated control. The model GHE-260CNC7 high speed & dry cutting CNC gear hobbing machine is of 7 axes one with 4 axes coordinated control. They adopts dry cutting for the environmental protection and has the functions of chamfering and deburring. Based on the principle of generating method, and by electronic gearbox(EGB), these machines are designed to cut cylindrical spur & helical gears, dual & cluster gears, crowning or slightly tapered gears, splines, wormwheels, and sprochets etc. They are suited for the industries that produce the gears on a large scale production, such as automobile, motorcycle, textile machinery, crane machinery and lift, etc.

Performance and Feature
1. The model GHE-260CNC7 high speed & dry cutting CNC hobbing machine is of 7 axes with 4 axes coordinated control. Its CNC axes are:

• A-axis--hob head swivel motion;
• B-axis--hob spindle rotary motion;
• C-axis--worktable rotary motion;
• X-axis--radial feed motion;
• Y-axis--tangential feed motion;
• Z-axis--axial feed motion;
• U-axis--mechanical hand rotary motion;
• Each motion axis is driven independently by an AC servo motor.

2. Dry-cutting process for green environmental protection is adopted. Tooth chamfering and deburring functions are integrated in the machine.
3. Both hob spindle and work spindle transmission system are equipped with clearance eliminating and damp adjusting mechanisms to ensure their rigidity and accuracy.
4. Hardened steel guideways and linear recirculating roller guidance system are used for each linear motion part, imported pre-loaded precision ball screw pairs are used, imported super precision and high rigidity compound bearings are used for supporting the ball screws. Therefore, the machine has high rigidity and well suited for high speed and heavy-duty cutting. For cutting the workpiece with module about 5mm.
5. Equipped with internal and external fully-enclosed guards, perfect chip conveyor and dust collector.
6. This machine embodies the developing trend and design concept of manufacturing industry in environmental protection, automation, flexibility, high speed, high efficiency, and function combination.
7. It is suited for cutting cylindrical spur & helical gears, worm wheels, slightly tapered and crowning gears, splines and sprockets, etc.
