Lapping is a machining process used to create a smooth, flat surface on a workpiece.

• Lapping involves rubbing two surfaces together with an abrasive and a lubricant to remove material and achieve a precise fit.

• It is commonly used in the manufacturing of precision components such as valves, pistons, and gears.

• Lapping can improve the surface finish and flatness of a workpiece, making it ideal for achieving tight tolerances.

• The process is often done by hand or with specialized ma...read more
