Typical Power Brush Applications
Deburring Power brushes are widely used to remove burrs created by other machining operations. Power brushes can completely remove burrs without creating secondary burrs or leaving two sharp edges. Unlike grinding tools, brushes are selective to an edge; they will remove the burr but none of the base material.
Surface Finishing Power brushes are excellent tools for improving surface finishes to gain a desired appearance. Brushes do not remove the base metal. They remove only the metal particles left on surfaces which have been ground or abrasive polished. Power brushing also tends to relieve stress created by other machining operations. Many different surface finishes can be obtained by using power brushes.
Edge Blending Power brushes are ideal for developing a rounded corner at the juncture of two surfaces. Power brushes perform this application without removing material on the surface adjacent to the edge or changing the part tolerance. This reduces stress concentration and part fatigue, increases part life and improves the surface finish.
Roughening Power brushes are uniquely suited for creating better bonds on surfaces such as rubber, leather plastics and nonferrous metals. Surfaces can be roughened prior to painting or bonding to achieve better adhesion.
Cleaning Power brushes are distinctly suited for removal of surface film, dirt, rust, heat treat scale, weld slag, corrosion and paint. Power brushes also remove varnish and insulation from electrical wire, motor stators, etc. fiber, synthetic and fine stainless steel brushes can be used for wet-cleaning operations.
