Abstract
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.

An abrasive tool having
- a support,
- a plurality of abrasive flaps,
- which are arranged on the support, and
- which each have a base and abrasive material, wherein the abrasive material is attached to the base by a binder, wherein at least one of the abrasive flaps has a cured filling resin for reinforcement and for reduction of cyclical deflection, and the respective base comprises at least one thread, which is soddened with the filling resin.
