Abrasive Oxide Abrasive Microgrit
Microgrit is a high quality emery especially designed for use in precision lapping applications where close tolerances and minimal subsurface damage are required.
This precision powder is made up of flat platelets of white aluminium oxide. The platelets shape of the crystal allows each grain to orient itself parallel to the lap and the lens surface. The pressure is therefore distributed uniformly over a large area of the crystal surface maximising particle life and minimising excessive gouging and subsurface damage.
