When using a brush tool, select an appropriate rotational speed to avoid brush wear or breakage caused by high speed. Employ climb milling with uniform and smooth feed rates, avoiding excessive pressure on the workpiece. Rely on elastic grinding for deburring. During machining, maintain a slight tilt angle to prevent vertical pressure, thereby extending the tool's lifespan. Process planes, holes, and edges in separate steps with clean, continuous tool paths to minimize directional impact. Regularly remove chips to prevent brush entanglement. Choose the appropriate abrasive brush based on the material, and inspect brush wear during machining. Replace the brush promptly if deformation or detachment occurs. No excessive coolant is required throughout the process—minimal cooling suffices to ensure uniform and stable polishing, enhancing surface quality.
