Cartridge rolls, one of several types of deburring tools, are manufactured by wrapping abrasive cloth materials around appropriately-sized mandrel. Available with aluminum oxide grain, silicon carbide grain or zirconia/alumina grain, units are suited for polishing, blending, deburring and flash removal operations. Fresh abrasive grain is exposed as outer layer of cartridge roll wears away. Cartridge rolls are available in 1/8-11/2 in. diameter and 3/4-2 in. length with grits from 36-320.
Designed to be long-lasting, fresh abrasive grain is exposed as the outer layer of the cartridge rolls wears away. Cartridge rolls are used on hand-held power tools and are mounted on mandrels designed to securely hold during operations. They come in a variety of styles-straight, full taper, half taper and sidewall-and are application and operator specific in edge breaking and machine tool mark removal.
In general, deburring is a finishing method used in industrial settings and manufacturing environments. Metal is frequently machined using many processes in order to create pieces of specific shape and size, though wood and plastic are also deburred. For example, metal may be welded, molded, cast, trimmed, slit or sheared. These procedures often create ragged edges or protrusions. The raised particles and shavings that appear when metal blanks are machined are referred to as burrs, and the process by which they are removed is known as deburring.
Deburring may be accomplished by one of several methods. Abrasive substances may be applied, or abrasive cloths may be used to rub the metal in order to remove thin shavings and small notches, as well as to polish the piece (hand deburring). In other cases, sanding may be necessary, even if it means rigorous sanding with a machine for more troublesome deformities (semiautomatic deburring, abrasive flow machining, thermal energy method, and so on). Among all the types, semiautomatic deburring and hand deburring are the only ones that use cartridge rolls; repetitive filing or use of a grinder to smooth away nicks and fragments are key in cartridge roll deburring.
The use of cartridge rolls may take extra effort on your part, compared to using other tools. Then again, it's the best tool to be used when controlled or steady deburring is need, or else the part or material will be thrown, which can cause you injury or worse. Keep in mind, always use fresh rolls after every deburring, because they have a tendency to wear out.
