Abrasive equipment classification

The classification of abrasive equipment in the stone industry is relatively complex. According to the source of raw materials, it can be divided into natural abrasives and artificial abrasives. The only natural abrasive used in the machinery industry is oil stone. Artificial abrasives are distinguished by their basic shape and structural characteristics. They include grinding wheels, grinding heads, whetstones, sand tiles (collectively referred to as bonded abrasives) and coated abrasives. In addition, abrasives are also conventionally classified as a type of abrasive.

Ordinary abrasive bonded abrasive tool is a grinding tool with a certain strength, which is formed by bonding a common abrasive to a certain shape with a binder. Generally composed of abrasives, binders and pores, these three parts are often referred to as the three elements of bonded abrasives.

Bonded abrasives can be classified into ordinary abrasive bonded abrasives and superhard abrasive bonded abrasives, depending on the abrasive used. The former uses ordinary abrasives such as corundum and silicon carbide, and the latter is made of superhard abrasives such as diamond and cubic boron nitride.

Commonly used abrasive bonded abrasive features include: shape, size abrasive, grain size, hardness, tissue, and bonding agent. The method of determining the hardness of the abrasive tool, the hand-cone method, the mechanical taper method, the Rockwell hardness tester, and the sandblast hardness tester method are commonly used.
