Sigma Green Grinding Wheels

July 12, 2012

A full line of abrasive grinding wheels that come in various grits and sizes, featuring 4-½" diameters and many other sizes in-stock for immed-iate delivery, is available from Rex-Cut Abrasives. Rex-Cut Sigma Green Premium Grinding Wheels are designed for aggressive grinding applications on stainless steel, mild steel, hard face, titanium, and aluminum. Available in 36, 46, and 60 grits in 4", 4-½", 5", and 7" dia. sizes, with 36 grit 3/16" thick and 46 and 60 grit 18" thick, they have a zirconia/ceramic grain with a proprietary bonding and wheel design.

Capable of reportedly cutting up to 50 percent faster and running 20 percent cooler than aluminum oxide grinding wheels on 316 stainless steel, Sigma Green Premium Grinding Wheels provide smooth, quiet, and controlled grinding action. Designed to remove heavy welds fast, they prevent the discoloration and warping of stainless steel and other highly alloyed materials.

Rex-Cut Sigma Green Premium Grinding Wheels are priced from $ 3.99 (list) each, depending upon size and quantity; with most sizes in-stock for immediate delivery.

  • 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.

  • grinding


    Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
