Abrasives are versatile materials used to shape or finish workpieces by rubbing against them. They are often minerals or synthetic materials that are hard and sharp, allowing them to wear away softer materials. Abrasives are used in various industries for grinding, polishing, cutting, and sharpening. They come in different forms, including bonded and coated abrasives, and are available in various grit sizes. Coated abrasives consist of a thin layer of abrasive grain attached to a substrate, such as paper or cloth. They are used for a wide range of applications, including metalworking, woodworking, and glass processing. Abrasives are essential for producing high-precision parts and components, and their use is widespread in various industries.
