摘要： An abrasive tool includes a support, on which a plurality of abrasive flaps is arranged. The abrasive flaps each have a base and abrasive material, which is attached to the base by means of a binder. To increase the useful life and total material abrasion, the abrasive flaps are reinforced by a cured filling resin. The reinforcement of the abrasive flaps reduces the cyclical deflection thereof around a zero position due to workpiece machining, thereby avoiding increased wear on the abrasive flaps.

摘要： A grinding tool has a main body having at least one fiber ply embedded in a binder. An abrasive layer is arranged on the main body. The at least one fiber ply is arranged in the binder in a partially movable manner. As a result, a relative movement that ensures high vibration and noise damping is achieved within the main body and within the at least one fiber ply.
