sive paper is coarse, medium, fine or very fine. Grain 100-180, for example, is a fine grain. The
numbers (40, 60, 80, 120) indicate the number of meshes per 25.4 mm length of one sieve side
of a vibrating sieve. The grain mixture of the abrasives is separated by vibrating screens
according to grain size. The higher the grain number, the finer the abrasive paper.
