Features
- These vertical CNC gear hobbing machines cover multiple size options and are built for high accuracy, efficient cutting and stable operation.
- All models work with the FANUC Oi-MF Plus control system, using a six-axis layout with four-axis interpolation in a vertical configuration for precise motion control.
- The hob spindle reaches 1500 r/min, while the workpiece spindle reaches 150 r/min. A 160 mm cutter-shift travel supports deeper tooth profiles when required.
- The X and Z axes use precision ball screws and sliding guideways, helping maintain good positioning accuracy and rigidity during continuous machining.
- The CNC vertical gear hobbing machines can produce cylindrical gears, worm wheels, sprockets, timing-belt pulleys, flexsplines and splined shafts. Radial hobbing is available for worm-wheel machining, making the equipment suitable for commercial-vehicle gears, passenger-vehicle gears and construction-equipment gears in the small-to-medium module range.
- Accuracy levels reach GB7 during mass production and GB6 for precision cutting.
- The interface includes software made for gear cutting, where operators can set parameters, adjust the lead and fine-tune the cut through a simple, easy-to-read panel.
Applications
Suitable for medium- and large-module gear machining, with typical industries and workpiece types including:
- Industries: motorcycles, industrial robots, gear reducers, aerospace components, automotive transmissions (including small passenger-car gearboxes up to m≤6), and construction machinery.
- Workpieces: spur and helical cylindrical gears, crowned gears, gears with small tapers, splined shafts, sprockets and worm wheels. Suitable for high-precision or high-efficiency machining of steel gears up to module 6.
Comprehensive high-precision gear machining solutions for a wide range of industries
