Bonded abrasives are abrasive grains fused with a bonding agent into a solid tool, such as a wheel, used for grinding, cutting, and surface finishing. CUMI Abrasives manufactures bonded abrasives — including resin-bonded thin wheels, vitrified grinding wheels, super abrasives, and non-woven products. This in-house control over raw inputs and production supports consistent grain distribution and bond strength, which directly affects cutting precision and product lifespan on the customer’s production floor. All our products comply with EN standards. Products within our range are compliant with the ‘Organization for Safety of Abrasive’ ( oSa) norms.
Coated abrasives are abrasive grains bonded onto a flexible backing such as paper or cloth, used for sanding, polishing, and surface finishing. CUMI Abrasives manufactures coated abrasives — including belts, docs, flaps, mops, rolls, and sheets across an opening price point range to a pure play ceramic range. With production facilities in Asia and Europe, CUMI owns one of the largest coated maker facilities in the world.
