Straight Grinding Wheels

Sharp Abrasives offers a wide range of Firetech Straight grinding wheels; resin bonded grinding wheels and more. These are by far the most common style of wheel and can be found on bench or pedestal grinders. They are used on the periphery only and therefore produce a slightly concave surface (hollow ground) on the part. This can be used to advantage on many tools such as chisels. These resin-bonded abrasive products have higher tensile strength as compared to the vitrified bonded abrasive products and therefore these Straight grinding wheels can withstand heavy grinding pressure and mechanical shocks. 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, but the history of grinding wheels began with natural composite stones, such as those used for millstones. Sharp Abrasives manufacture these Straight grinding wheels in a precise and tightly controlled process, due not only to the inherent safety risks of a spinning disc, but also the composition and uniformity required to prevent that disc from exploding due to the high stresses produced on rotation.
