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.
Abrasive Grinding wheels are made of natural or synthetic abrasive minerals bonded together in a matrix to form a wheel. While such tools may be familiar to those with home workshops, the general public may not be aware of them because most have been developed and used by the manufacturing industry. In this sector, grinding wheels have been important for more than 150 years.
As the grinding wheel applies forces to remove material from the work piece, the work piece applies resistance forces to the grinding wheel. Overtime, these forces lead to fracturing of abrasive grain from the bond in the case of vitrified and metal bond wheels. In the case of organic and resin bond wheels, new abrasive grains are released under heat. The resultant is a release of dull grains and exposure to the new sharp grain beneath it.
Grinding wheel, the most important abrasive product, is involved in the manufacturing of machinery, electrical, electronic components, and automotive components. It is made of an abrasive grain, and is a self-sharpening cutting tool. The majorities of grinding wheels made have a vitreous, ceramic bond, and are made of clays and feldspars.
Bonded abrasives, such as those in grinding wheels, are made up of grains that are held together by a fixative material can be used to cut-off and to grind on different hand-held machines, petrol saws, straight grinder, and angle & vertical grinder. Each product is designed to give a speed of cutting requirements, specific finish, and stock removal.
