G 30

OERLIKON Bevel Gear Grinding Machine


Economical concept for high-precision final machining of bevel gears

Thanks to continuous further development of the vertical concept, the G 30 bevel gear cutting machine sets new standards in grinding. The grinding machine utilizes an optimized axis arrangement resulting in reduced approach paths that ensure a significantly reduced load on the drive components and at the same time a more rigid design of the complete system. The G 30 can be optionally equipped with a side loading door. This allows easy loading in automatic mode using a machine-integrated loading shuttle or handling robot. For series production, the machine also offers a range of process monitoring functions.

  • Ongoing advancement of the vertical concept to eliminate grinding sludge deposits in the working chamber
  • Extremely rigid, thermally stable machine for optimal machining results, even for highly productive processes
  • Side loading with machine-integrated shuttle or handling robot (optional)
  • Modern operating software with touchscreen display and a clear screen layout
  • Optimal energy (e2) efficiency thanks to recovery and on-demand control of units
