What are lapping and honing? 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.
The lapping tool must have grooves to store abrasives and prevent the accumulation of excess abrasives; It must have certain geometric accuracy, enough stiffness, compact material without impurities and uniform hardness. 2) Materials of lapping tools. Cast iron is suitable for grinding various materials;

The EVG Series Vertical Wafer Grinding Machine is designed to grind advanced materials to a high degree of precision in flatness and surface quality, often reducing or eliminating the need for lapping.
The lapping process involves passing a part between one or two large flat-lap plates or platens in a carrier fluid containing an abrasive. Duval achieves a flat, polished surface by applying precision surface grinding methods that exceed the flatness of typical rough grinding, usually generating surface flatness within .0002 – .00005".
