    摘要： With a method for the production of a grinding tool, a tool base body is provided, which configures a three-dimensionally shaped adhesive sur-face by application of a bonding agent. The tool base body is positioned in a way that the adhesive surface is arranged in an electrostatic field, be-tween a first electrode and a second electrode. Into the electrostatic field, abrasive grains are introduced, which, due to the electrostatic field, move towards the adhesive surface and adhere to same. The grinding tool produced in this manner has a three-dimensionally shaped abrasive grain layer. The production of the grinding tool is simple, flexible and economical. The grinding tool has a randomly shaped abrasive grain layer and can be applied in a manifold manner with a high cutting performance and a long service life.

    摘要： A roughing grinding tool has a supporting body and at least one abrasive circle. The supporting body includes an abrasive grain for roughing grinding. The supporting body serves to support the at least one abrasive circle and itself for roughing grinding. The roughing grinding tool is easy to produce and robust and has a high removal capacity in conjunction with a long service life.

    摘要： A grinding disc comprises a grinding layer formed of grinding grains bound by means of a binding agent. Reinforcing fabrics are embedded in the grinding layer on the outer sides of the grinding layer. At least one additional fabric is arranged on at least one of the reinforcing fabrics and has a respective diameter which is smaller than the diameter of the rein-forcing fabrics. The at least one additional fabric stiffens the grinding disc in a region around a central opening and improves the properties of the grinding disc during rough machining and/or cutting off

    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.
