Abrasive is a very hard material that can be used for grinding, polishing, sharpening, cutting, buffing, drilling, and honing the surfaces, they are different in synthetic or natural. Many a synthetic abrasive is productively equivalent to an organic mineral. It differs that synthetic minerals are produced instead of mined. While, if natural minerals are impure, they may be less valuable. Nowadays, they are synthetic. Some of the abrasive minerals (zirconia alumina) appear naturally though sufficiently more intricate and expensive to acquire , because of this, synthetic stones are made use of industrially. These are also called artificial abrasives. Other forms of artificial abrasives such as ceramics, silicon carbide (carborundum), zirconia alumina, alumina or aluminum oxide.

Abrasives structured for individual purposes. Most of the organic abrasives are minerals, Generally synthetic and natural come in a gamut of shapes, commonly known as coated or bonded abrasives, including wheels, belts blocks, discs, rods, sheets & loose grains. Manufactured abrasives are classified into two types coated, and bonded abrasives. Bonded is one of the abrasive materials that are hold within matrix, and aluminum oxide.


Abrasives contain sintered material. This type of matrix is known as a binder also called as clay, rubber or resin. This combination of binder & the abrasives are normally structured as wheels, sticks, blocks. These are commonly used as aluminum oxide, silicon carbide, garnet, tungsten carbide.


Bonded abrasives are required to be dressed after they are used. Dressing includes various processed including cleaning the waste material from the surface and revealing the new grit. It depends upon the abrasive and how it is used.


Coated abrasives are also minerals that are used in the same way as bonded abrasives. Sandpaper is a best example of coated abrasive. Coated abrasives are structured for use in orbital sanders.
