ABRASIVE is a material, often a mineral, that is used to shape or finish a work-piece through rubbing which leads to part of the work-piece being worn away is a hard substance used for grinding, finishing or polishing of a less hard surface, or the material that causes wear is called 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.
