  • abrasive

    abrasive

    Substance used for grinding, honing, lapping, superfinishing and polishing. Examples include garnet, emery, corundum, silicon carbide, cubic boron nitride and diamond in various grit sizes.

  • aluminum oxide

    aluminum oxide

    Aluminum oxide, also known as corundum, is used in grinding wheels. The chemical formula is Al2O3. Aluminum oxide is the base for ceramics, which are used in cutting tools for high-speed machining with light chip removal. Aluminum oxide is widely used as coating material applied to carbide substrates by chemical vapor deposition. Coated carbide inserts with Al2O3 layers withstand high cutting speeds, as well as abrasive and crater wear.

  • fatigue

    fatigue

    Phenomenon leading to fracture under repeated or fluctuating stresses having a maximum value less than the tensile strength of the material. Fatigue fractures are progressive, beginning as minute cracks that grow under the action of the fluctuating stress.

  • polishing

    polishing

    Abrasive process that improves surface finish and blends contours. Abrasive particles attached to a flexible backing abrade the workpiece.

A new line of Type 27 cotton fiber flexible abrasive wheels for blending and finishing aluminum in one-step without needing waxes or compounds has been introduced by Rex-Cut Abrasives.

Rex-Cut Type 27 Max Flex Cotton Fiber Wheels feature multiple cotton fiber layers that are impregnated with aluminum oxide grains and then pressed and bonded together to constantly reveal fresh abrasives as they work. Capable of finishing aluminum in one-step without waxes or compounds, they are more flexible than conventional abrasive wheels, are non-loading, and provide smooth, chatter-free operation which helps reduce operator fatigue.

Providing a wide surface contact area for optimum blending and finishing control, Rex-Cut Type 27 Max Flex Cotton Fiber Wheels produce a uniform finish and have a polishing affect because of their cotton bond. Suited for aluminum fabrication such as tanks and vessels, horse trailers, marine fabrication, and more, available in 4-½", 5" and 7" sizes in A36 and A54 grits.
