Coated abrasives are used in grinding wheels, abrasive sticks or stones. Abrasive stones or sticks are used for honing internal or external surfaces and sharpening edges. Abrasive grains of coated abrasives are in different bond types. They are used widely to take out surface materials like ceramics, metal, plastics, glass, and paint in manufacturing and industrial plants. Most uses require a controlled flexing of the coated abrasive, base on the contour of the object to be polished and the diameter and size of the contact wheel. The polishing of a flat object with a hard, large diameter contact wheel requires little or no flex. A very irregularly contoured object polished on a small or soft contact wheel will require a very flexible coated abrasive to permit the abrasive to follow the contour. The abrasive materials in coated abrasives are the same as the materials used in bonded abrasives, but is applied differently.
