GBP 57 SiC Wheel brushes Round brushes with extremely tightly packed abrasive bristles (right to the edge of the brush) embedded in the plastic pad. The bristles support each other, giving a highly stable shape. Very long working life. Nylon bristles with very high silicon carbide grit content for general-purpose use. Advantage: ■ Workpiece post-processing directly after the machining process. ■ Reproducible results due to continuous exposure of the abrasive grit. ■ Process reliability thanks to high stability and accuracy of the shape. ■ Quick and secure mounting without further accessories. ■ Very high concentricity. Application: On CNC machining centres and when used by robots, preferably wet grinding with cooling lubricant. For grinding side faces and inner faces: precise deburring (e.g. threads), edge rounding, delicate work after milling, surface finishing. Note: Special versions available on request.
