Advantages of lapping

What is lapping? Lapping is the first mechanical precision finishing  operation in done to achieve high dimensional accuracy. It helps you achieve positive sealing by obtaining high degree of flatness and surface finish. The advantages of lapping for obtaining fine flatness and surface finish have long been recognised by production and design engineers. Advantages: A wide variety of materials can be lapped. Flatness to one light band (0.0003 mm) on 100 dia. Surface finish to less than 0.2 µRA.
	Some reasons why lapping machines help to transform a costly, rarely used, hand operation to a fine accuracy, economical process:-
Parts of different shapes, thickness and material can be lapped.GMT has supplied lapping machines to lap various metals, plastics, glass, ceramic and granite. Because the lap plate continuously maintains its flatness, production is not interrupted. Appropriately selected diameters of the conditioning rings result in optimum lapping area. Lapping cycles are controlled by an automatic and adjustable digital display times.
