ABSTRACT
Power brush tools used in industry are classified into seven major categories as determined by their geometric shapes and construction. Each category or shape relates to the adaptability of the product to the application work to be performed, such as deburring, edge contouring, and cleaning, polishing, and surface conditioning, using the cutting and grinding fill materials. These major categories are wheel/radial, cup, disc, end, twisted-in wire, cylinder, and strip brushes. Power buffs are generally categorized as wheels and subdivided into the following seven major categories: full disc, packed, pierced, bias, ventilated, finger, and goblet. Goblet buffs are 6 inches or less in outside diameter with thickness to 4 inches, used to color buff internal surfaces, contours, and unusual inside geometric shapes. Bias buffs are the most popular and universally used for both cut and color buffing on semiautomatic machines and on fully automated manufacturing systems.
