The wheels are generally made from a composite material consisting of coarse-particle aggregate pressed and bonded together by a cementing matrix (called the bond in grinding wheel terminology) to form a solid, circular shape. Various profiles and cross sections are available depending on the intended usage for the wheel. They may also be made from a solid steel or aluminium disc with particles bonded to the surface. Today most grinding wheels are artificial composites made with artificial aggregates.
Available in White Aluminium Oxide, a better choice for light metal removal and sharpening of high speed tool steels. Silicon Carbide for precision engineered grit size and hardness to maximize cut rate, finish and wheel life in 57A (Gray) for ferrous metals: 39C (Green) for nonferrous materials.
Available in 150 x 20 (A36 to A120), 200 x 25 (A36 to A120), 200 x 40 (A46 to A60). Specialist sizes are available on request
