For your kind reference, we are able to lap or grind 1 bevel gear and 2 pinions in the same production batch, but they cannot be lapped or ground all together at the same time, as lapping work must be carried out in one-to-one mating pairs. We can grind all three components within the same production batch, and please feel rest assured that after lapping or grinding, each pinion will go through independent meshing test with the bevel gear one by one. Every pair will be mated, lapped and checked individually to secure perfect meshing test performance of each pair set.
