Resin Bond is the commonest bonding both in traditional abrasive wheels and Superabrasives (Diamond and CBN) grinding wheels. Resin bond can make the abrasive tips exposed quickly. It is applied to be used wet or dry for most tool making, resharpening and toolroom reconditioning applications and also in grinding and polishing glasses, stones, silicon and many other non-metal materials.Generally, Diamond and CBN are called “Super Abrasives” or “Superhard Materials”. Obviously, the wheels manufactured with these abravises are called Diamond or CBN grinding Wheels.After years’ developing, RZ developed bonding for different application.
