What is sandstone grinding wheel?

Abrasives are tools used for grinding, grinding and polishing. Most sandstone grinding wheel are artificial abrasives made from abrasives and binders, as well as natural abrasives that are processed directly from natural mineral rock. In addition to being used extensively in the mechanical manufacturing and other metalworking industries, sandstone grinding wheel are used in the processing of food processing, the paper industry and non-metallic materials such as ceramics, glass, stone, plastics, rubber and wood.

During the use of the sandstone grinding wheel, as the abrasive particles become dull, the abrasive particles may partially or completely detach from the sandstone grinding wheel due to partial chipping or bond cracking of the abrasive particles and abrasion of the abrasive on the work surface. Tools are constantly emerging. The cutting edge or the continuous exposure of new sharp abrasive particles allows the sandstone grinding wheel to maintain cutting performance for a certain period of time. This self-sharpness of the sandstone grinding wheel is a prominent feature of the sandstone grinding wheel compared to conventional tools.

As early as the Neolithic Age, humans began using natural grinding stones to process sandstone grinding wheel such as stone knives, stone axes, bones, horns and teeth. In 1872, natural abrasives and clay were combined in the United States. Ceramic grinding wheel; about 1900, the introduction of artificial abrasives, and the production of a variety of abrasives made of artificial abrasives, created conditions for the rapid development of grinding machines and grinding machines. Since then, the proportion of natural abrasives in sandstone grinding wheel has gradually declined.

Abrasives are classified according to their raw materials, including natural abrasives and artificial abrasives. Natural abrasives commonly used in the machinery industry are just oilstones. Artificial abrasives differ according to their basic shape and structural characteristics. There are five types of grinding wheels, grinding heads, oilstones, sand bricks (collectively referred to as fixed abrasives) and coated abrasives.

In addition, it is customary to classify abrasives as an abrasive. Depending on the abrasive used, the fixed abrasive can be divided into ordinary abrasive abrasives and superabrasive abrasives. The former uses ordinary abrasives such as corundum and silicon carbide, while the latter uses superabrasives such as diamond and cubic boron nitride. In addition, there are some special varieties, such as sintered corundum abrasives. Ordinary abrasive bonded abrasives are abrasives in which a fixed abrasive is consolidated into a shape by a binder and has a certain strength. Usually composed of abrasives, adhesives and holes, these three parts are often referred to as the three elements of bonded abrasives.
