The earliest use of grinding in humans dates back to the primitive society. In the matriarchal society, people have begun to use the simplest stone tools, and these simplest stone tools are rubbed together by simple stones. People use these simplest tools to hunt and cultivate. At that time, people's clothes were simple, but they still had the aid of a blade, which was inseparable from grinding. In the Neolithic Age, humans began to use natural grinding stones to process tools such as stone knives, stone axes, bones, corners and teeth. In the thirteenth century, Chinese people began to use natural gum to glue shell powder to sheepskin. The paper is made of friction tools, the earliest coated abrasives known in the world. At the same time, Italians on the Mediterranean coast began to use simple coated abrasives.
The second stage of the development history of grinding processing 1840---1900 years ago, with the development of industry, the hardness of the materials being processed is getting higher and higher, the original simple abrasives can not meet the needs of development, so people began We are looking for abrasive materials with higher hardness. We have found natural corundum, yellow gems, diamonds and other materials. After crushing these natural materials and mixing them with clay, they are fired into abrasive tools with a certain shape. That is, around 1900, artificial abrasives were introduced, and various grinding wheels made of artificial abrasives were successively produced, which created conditions for the rapid development of grinding and thin flat cutting disc machines. Since then, the proportion of grinding wheels in the grinding tools has gradually increased.
Grinding wheels belonging to the hardware industry have played a vital role naturally. Grinding wheels have strengthened the technological innovation of production, improved the level of production technology, opened the "bottleneck" that restricts the product innovation ability and enterprise technology level, and timely introduced new grinding wheels. It is applied to the existing equipment of the enterprise, prolonging its technical life, improving its performance, and ensuring product quality at the source of production.
With the rapid development of China's economy in recent years, the technological innovation of grinding wheels has been continuously strengthened. In the future, it will become the largest product category among the largest categories of abrasives in China. At the same time, due to the unique advantages of grinding wheels in the later stage of grinding industrial chain, The application of the grinding wheel in polishing is promoted.novation of grinding wheels has been continuously strengthened.
