OERLIKON Bevel Gear Grinding Machine


Economical concept for high-precision final machining of bevel gears

Thanks to its outstanding grinding performance and universal design, this CNC-controlled bevel gear grinding machine from the G model series is an extremely economical concept for high-precision final machining of the curved-toothed bevel gears of any gearing system as well as face-type clutches. These machines operate up to a ring gear diameter of 850 mm. The G machines are equipped with a side loading door for automation purposes, making loading using handling robots easy during automatic operation.


  • CNC machine for high-precision final machining of the curved-toothed bevel gears of any gearing system as well as face-type clutches
  • Vertical grinding spindle for optimal, unobstructed downward chip flow
  • Ring gear diameters to 850 mm
  • Easy access to all additional components, including oil mist extraction system, grinding oil return pump and hydraulics
  • Minimal setup times
  • Grinding wheel profiling takes place under CNC path control with diamond dressing roll
  • Ideally suited for automatic loading
  • Energy efficient (e2)

* With large outside diameter, the smallest spiral angle must be checked dependent on the axis traversing path.

The above-mentioned maximum values were determined for industry-typical gear units.
If necessary it has to be examined whether maximum values can be combined.
