Abrasive grains of corundum are glued onto abrasive paper with the aid of binders. Corundum
is aluminium oxide with the chemical name Al
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.
