Grinding wheel is a tool that plays the role of grinding, cutting and polishing in the process of heavy industry and product manufacturing. They are known as the “teeth of heavy industry” and are also the beautician of the product’s appearance. Without their presence, heavy industry can hardly stand on its own, and their quality also determines the quality of the products produced.

China is one of the most ancient countries in the use of grinding processing methods, such as in the ancient scientific masterpiece “Tiangong Kaiwu” there is “cut, learn from, cut, grind” idiom, and “grinding” refers to the grinding processing.

The first stage of the development history of grinding

The first stage, actually, is the earliest use of grinding, dating back to the primitive society, in the matriarchal society, people have started to use the simplest stone tools, and these are made of simple stones rubbing against each other. People use these simplest tools for hunting and farming. Although people’s clothes were simple at that time, they still needed the help of blade, which could not be separated from grinding.

In the Northern Wei Dynasty, a man named Cui Liang created a water mill for grain processing. In the Jin Dynasty, Liu Jingxuan created a stone mill that could run eight natural rock millstones at the same time. Pottery grinding and grinding appeared in the Tang Dynasty. These grinding tools were unearthed in the tomb of Wang Chen in Changzhi County, Shanxi Province. After expert investigation in the Song Dynasty also early existence of nine speed grinding.

In the 13th century, during the Yuan Dynasty, the Chinese began to glue shell powder onto parchment with natural gum to make friction tools, the earliest known coated abrasives in the world. At about the same time, the Italians on the coast of the Mediterranean also began to use simple coated abrasives.

The second stage of the development history of grinding

This stage appeared new characteristics, that is, with the development of the industry, the processed material hardness is higher and higher, the original simple abrasives can’t satisfy the need of development, so people began to seek higher material to do abrasive hardness, has found a natural jade, topaz, natural stone material such as people put these natural material after broken, when mixed with clay firing has certain shape of abrasive, to carry on the processing.

It can be said that the beginning of the use of higher hardness of natural abrasive is a general characteristic of this period. But the production of all natural abrasives is not concentrated, and the quantity and quality are not uniform, and it is difficult to maintain stability. All these limitations and the rapid development of the industry is becoming more and more inadaptable.

The third stage of the development history of grinding

This period was characterized by the emergence and use of artificial abrasives.

In 1983,the SiC artificial abrasive resistance furnace which is first appeared in human history of artificial abrasive, and then someone invented artificial corundum abrasives with arc furnace, the emergence of these artificial abrasive significance is significant, only ended the human use of natural abrasive, but not the use of artificial abrasive history, from then on, industry began to have a large number of relatively cheap and quality is relatively stable, the production and steady increase of artificial abrasive grinding tools, given a boost to be ground material processing and rapid growth, On the other hand, the development of grinding also promotes the rapid development of abrasive tools.

Throughout the world’s powerful heavy industries, there are world-renowned grinding wheel manufacturers, such as 3M in the United States, VSM in Germany, Bison in Japan, Deer brand in South Korea and so on. In the process of heavy industrialization in their country, these grinding wheel manufacturers are also growing step by step, and the quality of the grinding wheel is also improving little by little. With the improvement of the quality of the grinding wheel, they are able to process higher hardness materials and produce equipment with better precision.

The current grinding wheel industry may still be in the relatively extensive stage, but the pace of product upgrading is also very fast. The choice of high-quality products on the market is becoming more and more obvious, and inferior products are being eliminated rapidly. This puts forward higher requirements for our abrasive and abrasive enterprises, that is, to produce better products, choose and provide better products.

Good equipment further improves the quality of the products produced. In their interaction and mutual improvement, the products are recognized by people, the sales increase greatly, and the profits are considerable. The heavy industry is able to develop further, so the heavy industry becomes strong and the country becomes rich and powerful. The role of grinding wheel in the development of heavy industry is not to be underestimated.
