Cotton-Fiber Mounted Points

September 01, 2011

A full line of cotton fiber mounted points that are ideally suited for EOAT (end-of-arm-tooling) in automated metal deburring and finishing applications is available from Rex-Cut Products Inc.

Mounted Points are made with multiple layers of non-woven cotton fiber and either aluminum oxide or silicon carbide abrasive grains that are pressed and bonded into standard A, B and W-shapes. Ideal for EOAT in robotic finishing operations, they reveal fresh abrasives as they deburr and finish in one step and can be made in custom shapes to match OEM requirements.

Suitable for stainless steel, titanium, Inconel, exotics, and aluminum, Rex-Cut Cotton Fiber Mounted Points are offered in hard and soft bonds and can be produced in custom shapes and sizes for finishing slots, seams, internal cavities and other applications without changing part geometry. An 80 Grit soft bond is capable of leaving a 16-20 RMS finish on stainless steel. Rex-Cut Cotton Fiber Mounted Points for EOAT are often developed to match OEM application and significantly outlast conventional mounted points, claims the firm. They are priced according to shape, size, and quantity.

  • 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.
