Development history of grinding wheel

Grinding wheels are tools for grinding, cutting and polishing in the process of heavy industry production and product manufacturing. They are called "heavy industry teeth" and are also beauticians of the appearance of the product. Without their existence, it is difficult for the heavy industry to gain a foothold, and their quality also determines the quality of the manufactured products.

The first stage of the development history of grinding

The first stage is actually the earliest use of grinding by humans. It should be traced back to the primitive society. In the matriarchal society, people have begun to use the simplest stone tools, and these simplest stone tools are obtained by rubbing each other with simple stones. . People use these simplest tools to hunt and cultivate. At that time, although people's clothes were simple, they still had to be assisted by blades, which was also inseparable from grinding.

The second stage of the development history of grinding

At this stage, new features emerged, that is, with the development of industry, the hardness of the processed materials is getting higher and higher, and the original simple abrasive tools can not meet the needs of development, so people began to seek higher hardness materials to do.

So people began to look for materials with higher hardness to make abrasives, and found materials such as natural corundum, topaz, natural stone, etc. People crush these natural materials and mix them with pottery clay, then burn them into abrasive tools with a certain shape for processing.

People crush these natural materials and mix them with pottery clay, then burn them into abrasive tools with a certain shape for processing.

It can be said that starting to use natural abrasives with higher hardness is a common feature of this period. However, the production of all natural abrasives is not concentrated, and the quantity is limited and the quality is not uniform. It is difficult to maintain stability. All these limitations and the rapidly advancing industry are increasingly unsuitable.

The third stage of the development history of grinding

The main feature of this period is the emergence and use of artificial abrasives.

In 1893, EG Acheson of the American company Cabronden used the resistance furnace to invent the SiC artificial abrasive. This is the earliest artificial abrasive in human history.In the future, some people have invented artificial corundum abrasives using electric arc furnaces. The emergence of these synthetic abrasives is of great significance.It has ended the history that humans can only use natural abrasives but not artificial abrasives. Since then, the industry has begun to obtain a large number of relatively low-cost, relatively stable quality, steadily increasing the production of artificial abrasive grinding tools, which has promoted the rapid growth of processed materials, of course, from the development of grinding processing Promote the rapid development of abrasives.
