COATED ABRASIVES The coated-abrasive name derives from one layer of abrasive grains being coated or deposited onto a versatile or semi-rigid backing material using an adhesive, like resin bond the grains to the backing material. This text examines the coating process, various sorts of grains, man-made minerals, and backing materials for coated-abrasive products for several metalworking applications.
COMPONENTS OF COATED ABRASIVES ABRASIVE GRAINS Coated abrasives are developed using abrasive grains. The foremost common abrasive grains are alumina, zirconium, ceramic, carbide, and garnet. CERAMIC It is a high performance, man-made abrasive, which is a very uniform, high-density grain structure. Ceramic is extremely durable and self-sharpening for extended life and a more relaxed cut.
ALUMINUM OXIDE It is a challenging, blocky shaped, man-made grain used for top speed grinding and finishing metals, wood, and other high-lasting materials without excessive fracturing or shedding. ZIRCONIUM Zirconium may be a very thick material with a singular self-sharpening characteristic, which provides its long life on massive stock removal operations.
SILICON CARBIDE It is a rigid, very sharp, man-made abrasive fitted to non-ferrous materials and non-metallic materials like concrete, marble, and glass. GARNET Garnet is formed of natural alumina, which may be a relatively strong but fragile bonding structure. Very inconsistent in comparison to synthetics.
