LIGHT BAND LAPPING

Lapping and Polishing

A soft material called a lap is charged with an abrasive and then used to cut a harder material. The abrasive embeds within the softer material, which then acts as a holder for the abrasive and permits it to score across and cut the harder material.

Lapping can be used to obtain a specific surface roughness; it is also used to obtain very accurate surfaces of flatness and appearance.

Surface roughness for typical applications fall in the range of .1 to 1 Ra.

Surface accuracy or flatness is usually measured in Helium Light Bands, one HLB measuring about 0.000011 inches (11 millionths of an inch).

We use a 16", 3 arm system with several lapping plate types that produces superior results, allowing tolerances down to 1/4 to 1/2 HLB measuring about .000003 to .000006 inches.
