CNC gear hobbing machines are primarily used to process various types of gears, such as spur gears, helical gears, circular arc gears, splines, and worm gears, using the generating method. They are characterized by high precision, high efficiency, and strong adaptability.
These machines employ a CNC system to control multiple motion axes (such as the hob rotation B-axis, workpiece rotation C-axis, radial feed X-axis, and axial feed Z-axis), achieving multi-axis linkage and thus precisely controlling the relative motion between the tool and the workpiece.
Their core functions include:
Wide Range of Gear Types: Capable of machining various gear profiles, including cylindrical spur gears, helical gears, herringbone gears, drum gears, small taper gears, spline shafts, and worm gears.
High-Precision Machining Capability: Modern CNC gear hobbing machines, through fully closed-loop control, electronic gearboxes (EGB), and mechanical backlash compensation technology, can achieve machining accuracy up to grade 6 or higher of GB/T10095.1-2008 standards, meeting the precision gear requirements of industries such as new energy vehicles and aerospace.
High-efficiency automated production: Supports automatic loading and unloading, quick tool change, quick fixture change, and other functions. Some models are equipped with oil mist separators and automatic lubrication systems, improving continuous operation capability and production efficiency.
Dry cutting and environmentally friendly machining: Some high-end models (such as the Chongqing Machine Tool YE3140) adopt dry cutting technology, eliminating the need for coolant and achieving green manufacturing.
Flexible programming and convenient operation: Enables form-based programming through CNC systems (such as FANUC, SIEMENS, GSK, etc.). Operators only need to input hob and workpiece parameters to automatically generate machining programs, lowering the operating threshold.
