Several Common Types of Abrasives Used in Grinding wheels

Cutting and grinding wheels and other bonded abrasives have two major components-the abrasive grains that do the actual cutting and the bond that holds the grains together and supports them while they cut. Generally, the structure of a grinding wheel is determined by the percentages of grain and bond and their spacing in the wheel.

The particular abrasive used in the cutting and grinding wheels is chosen based on the way it will interact with the work material. Each abrasive type is unique with distinct properties for hardness, strength, fracture toughness and resistance to impact. The good abrasive is to stay sharp with minimal point dulling.

Aluminum oxide

Aluminum oxide as the most typical China abrasive used in grinding wheels, is usually the abrasive chosen for grinding carbon steel, alloy steel, high speed steel, annealed malleable iron, wrought iron, and bronzes and similar metals. There are many different types of aluminum oxide abrasives, each specially made and blended for particular types of grinding jobs.

Zirconia alumina

Zirconia alumina actually are made from a different percentage of aluminum oxide and zirconium oxide. The combination results in a tough, durable abrasive that works well in rough grinding applications, such as cut-off operations, on a broad range of steels and steel alloys.

Silicon carbide

Silicon carbide is an abrasive can be applied for grinding gray iron, chilled iron, brass, soft bronze and aluminum, as well as stone, rubber and other non-ferrous materials.

Ceramic aluminum oxide

Ceramic aluminum oxide is a high-purity grain produced in a gel sintering process. The result is an abrasive with the ability to fracture at a controlled rate at the sub-micron level, constantly creating thousands of new cutting points. Because of the features of hard and strong, it is always used for precision grinding in demanding applications on steels and alloys that are the most difficult to grind.
