A Comparison of Honing and Lapping . Sep 14, 2017The lapping process is more gentle than honing and removes much less surface material. Therefore, the workpiece should be as close as possible to final size — achieved, for example, through doubledisk grinding — because lapping typically removes only " to " ( mm to mm) of material.
