Title: ABRASIVE BRISTLE, METHOD FOR PRODUCING SAME, BRUSH HAVING ABRASIVE BRISTLES AND METHOD FOR PROCESSING THE SURFACE OF A WORKPIECE BY WAY OF A BRUSH HAVING ABRASIVE BRISTLES
Abstract:
In order to produce an abrasive bristle, a plastics material is melted and granules composed of abrasive particles are mixed into the melt. The melt is extruded together with the abrasive particles to form a filament and the filament is subsequently processed and cut. In this case, it is provided for the plastics material to be a high-temperature-resistant polymer having a long-term use temperature ≥ 150°C and for the melt to be extruded with the abrasive particles at a temperature of ≥ 280°C. A brush fitted with corresponding abrasive bristles can be used to treat the surface of a workpiece, wherein the brush is rotated at a speed in the range of 3000 1/min to 12 000 1/min and is brought into abutment against the surface to be processed.
