Abstract: The invention relates to a coated abrasive tool including a carrier which has a carrier material and including an abrasive surface coating on a surface region of the carrier. The abrasive surface coating has abrasive functional particles and a thermoplastic binder for an adhesive connection between at least some of the abrasive functional particles and the carrier material. At least some of the abrasive functional particles on the surface region of the carrier are partly integrated into the carrier material and are connected to the carrier material, and at least some of the abrasive functional particles on the surface region of the carrier are additionally partly integrated into the thermoplastic binder, the thermoplastic binder being connected to the abrasive functional particles and the carrier material.

Abstract: An apparatus for feeding and dosing powder includes a powder storage container, an oscillating feeder with feeder with adjustable feeding rate for dispensing the powder to a powder outlet, a conduit arrangement for feeding the powder dispensed from the oscillating feeder in a feeding gas as a powder-gas mixture and for supplying the powder-gas mixture to a powder processor, wherein a decoupler is provided in the conduit arrangement to extract a defined proportion of the powder from the powder-gas mixture, a powder quantity measuring arrangement for detecting the decoupled powder quantity and for providing a powder quantity information signal, wherein the extracted powder quantity has a predetermined ratio to the fed powder quantity of the oscillating feeder, and controller configured to adjust the adjustable feeding rate of the oscillating feeder to a predetermined set value based on the powder quantity information signal provided.
