14 Gear Grinding Gear Grinding is performed with a grinding wheel that removes a very thin layer of the case hardening to generate the final profile The wheel can either be a profile grinder where the CNC motion of the wheel generates the profile or the profile can be designed into the wheel and ground onto the gear The latter involves grinding worms which are

Mar 01 2018 · The processing principle of the grinding machine for spiral bevel gears is the “virtual crown gear” As shown in Fig 8 the generating gear is formed by the comovements of X and Yaxis Due to geometric errors of the X and Yaxis such as positioning errors straightness errors etc the grinding machine has motion deviations in the X and Y directions
