Features
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.
