ABSTRACT
Industrial power-driven brushes and buffs used for mechanical deburring and surface finishing are inherently flexible tools that depend on the fill materials, which do the work, to bend and recover within their elastic limits. Abrasive monofilaments, clustered abrasive monofilaments, plastic-coated fiberglass, nylon, polypropylene, polyester, and carbon/graphite lead the growing list of man-made fill materials. Natural fiber, which is to say, materials grown by nature, include tampico, sisal, bass, bassine, bahia, palmetto, palmyra, cotton, linen, and others of less consequence. Tempered carbon steel wire is still used in power brushes more so than any other fill materials, with the tempered predominating over the untempered, hard-drawn variety. The chapter explores different wires includes beryllium copper—nonsparking wire, nickel silver, brass wire, brass-coated wire, zinc-coated wire, and plastic-coated wire. Abrasive monofilaments are made up of two components: abrasive grains and nylon. The category of cutting and grinding fill materials is the most rapidly growing in the industrial market.
