We all know that pencil lead is very soft and easy to be broken. There is such a substance that it is also made of carbon with pencil lead, but it is the hardest substance in the world. This is diamond.

Because of the characteristics of hard and rare diamond, so since ancient times people will regard its precious stones, and after cutting polished diamond is called diamond, is one of the most precious stones in the world.

The hardness of diamond is very high, it can be used to draw traces on almost all objects, diamond is sharp and not easy to heat, so the diamond is also used in the production process, such as the diamond package set in a variety of tools on the substrate, used to manufacture some grinding and cutting tools, this manufacturing process is electroplated diamond.

electroplated diamond

Electroplated diamond is the use of electroplating principle, with nickel will be embedded in the diamond sand on the workpiece, the diamond will be part of the package on the substrate, the other part of the exposed surface to form a strong wear-resistant working layer.

The purpose of electroplated diamond is to increase the cutting and grinding ability by packing dense diamond particles on the surface of metal workpieces. Various grinding tools manufactured by electroplated diamond technology are widely used in machinery, glass and building materials industries.

The formation of diamond needs to be formed in a special environment, so the origin of diamond is relatively concentrated, and the output is relatively small. Natural diamond does not meet the needs, so electroplated diamond is used for synthetic diamond particles.

Development history of grinding

Humans have a very long history of using various grinding tools to process objects. In ancient times, the ancients used sharp stones, animal bones, sticks and other tools to hunt and cut food. This is also the earliest grinding tool.

According to records in the Yuan Dynasty, China appeared a tool that used natural glue to stick shell powder on sheepskin for polishing. This is the earliest recorded package-mounted abrasive tool.

Since humans discovered various metals such as bronze, they began to use their more hard and malleable characteristics to process these metals into various tools, which are widely used in various grinding processes. Since then, humans have also entered the use of metal grinding. New era.

In modern times, with the rapid development of industrial production, the hardness of processed materials is getting higher and higher, and ordinary metal grinding tools can no longer meet their needs, so people began to look for materials with higher hardness as abrasives.
