Compared to traditional mechanical gear hobbing machines, CNC gear hobbing machines offer significant advantages in precision, efficiency, and automation, making them a core piece of equipment in modern gear machining.
Core features include:
High-Precision Machining: Utilizing full closed-loop control, electronic gearbox (EGB), and mechanical backlash CNC compensation technology, machining accuracy can reach GB/T10095.1-2008 standard level 6, with some high-end models even reaching level 5, meeting the high-precision requirements of new energy vehicles, aerospace, and other fields.
Multi-Axis Linkage and CNC Control: The fully CNC system controls hob rotation (B-axis), workpiece rotation (C-axis), radial feed (X-axis), axial feed (Z-axis), and tangential feed (Y-axis), achieving five-axis or even seven-axis linkage. It can machine various complex tooth profiles such as spur gears, helical gears, drum gears, splines, and worm gears.
High Rigidity and High Stability Structure: The machine bed is made of high-strength cast iron or artificial marble, enhancing thermal stability and vibration resistance. Key components such as the spindle, guide rails, and ball screws are mostly imported brands (e.g., FANUC, SIEMENS, Rexroth), ensuring long-term high-precision operation.
Highly Efficient Automation Capabilities: Supports automatic loading and unloading, quick tool change, quick fixture change, oil mist separation, and other auxiliary functions. Some models are equipped with a graphical user interface and "menu-based" configuration, achieving fully automatic continuous machining and significantly improving production efficiency.
Wide Applicability: Can process modules from m1 to m10 and even larger, with workpiece diameters up to φ400mm and above, suitable for multiple industries such as automotive, speed reducer, pump, construction machinery, and military.
Dry Cutting and Green Machining Trends: The new generation of models supports high-speed dry cutting, reducing coolant usage and environmental pollution. It also uses direct-drive motors (such as torque motors) to improve response speed and transmission efficiency.
