Abstract:
An abrasive belt for a belt grinding machine, the abrasive belt comprising:a support layer; an intermediate layer connected to the support layer; an abrasive layer connected to the intermediate layer; wherein the support layer is configured to transmit a drive output of the belt grinding machine onto the abrasive layer; wherein the abrasive layer is configured to allow flow of grinding particles through the abrasive layer; wherein the intermediate layer is configured to allow flow of the grinding particles through the intermediate layer; wherein the support layer is configured to allow flow of the grinding particles through the support layer; wherein the support layer is comprised of a material that is impenetrable to the grinding particles, but the support layer has a plurality of holes distributed uniformly over the surface area of the support layer; and wherein the holes have a maximum spacing to one another, wherein the maximum spacing is selected depending on the intermediate layer such that an essentially dynamic pressure-free grinding particle flow is generated through the abrasive layer, the intermediate layer, and the holes of the support layer.
