However, it is not necessary as any two solid materials that repeatedly rub against each other will tend to wear each other away examples include, softer shoe soles wearing away wooden or stone steps over decades or centuries or glaciers abrading stone valleys.
However, diamond files are a form of coated abrasive (as they are metal rods coated with diamond powder).Ībrasives generally rely upon a difference in hardness between the abrasive and the material being worked upon, the abrasive being the harder of the two substances. (For simplicity, "mineral" in this article will be used loosely to refer to both minerals and mineral-like substances whether man-made or not.)įiles are not abrasives they remove material not by scratching or rubbing, but by the cutting action of sharp teeth which have been cut into the surface of the file, very much like those of a saw. Some common uses for abrasives include grinding, polishing, buffing, honing, cutting, drilling, sharpening, lapping, and sanding (see abrasive machining).
This gives rise to a large variation in the physical and chemical composition of abrasives as well as the shape of the abrasive. In short, the ceramics which are used to cut, grind and polish other softer materials are known as abrasives.Ībrasives are extremely commonplace and are used very extensively in a wide variety of industrial, domestic, and technological applications. While finishing a material often means polishing it to gain a smooth, reflective surface, the process can also involve roughening as in satin, matte or beaded finishes. For the Puddle of Mudd album, see Abrasive (album).Īn abrasive is a material, often a mineral, that is used to shape or finish a workpiece through rubbing which leads to part of the workpiece being worn away by friction.
