The lapping process employed by this machine greatly improves the running performance of bevel gear pairs. Pinions and gears are meshed by up to three additional movements (axial, radial and vertical) which are controlled by cams. Tooth flanks are smoothed with the help of lapping medium, and contact patterns are corrected as necessary.
