A Comparison of Honing and Lapping - Metal Cutting …
Lapping is a sanding or polishing method used to create an accurate finish on a flat or domed surface of a part. Honing is a method of internal grinding used to achieve a precise surface finish and shape on the inside diameter (ID) of a tube, bore, or hole. The honing and lapping processes are both highly controlled.
