Similar to grinding, lapping uses abrasive grains to remove material and achieve a fine surface finish. The difference is that lapping uses the grains suspended in a fluid based on oil. The fluid with the grains is applied on the surface with a lapping tool used to apply pressure and move the grains back and forth to remove the irregularities.
