Since the macro geometry of bevel gears is directly dependent on the manufacturing process, there are limitations in the combination of pre-machining and hard finishing processes which are related to the geometry of the gaps.

Norton | Saint-Gobain Abrasives and Gleason Works Collaborate to Achieve a High Performance Gear Grinding Solution

One way to implement the growing performance requirements for transmissions is by optimizing the surface finish of the gearing. In addition to increasing the flank load capacity and the transmittable torque, this also allows for improvements in efficiency. On Oerlikon bevel gear grinding machines from Klingelnberg, fine grinding can be implemented efficiently in bevel gear production - even in an industrial serial process.
