What Is Polycrystalline Diamond Tool

As a superhard tool material, diamond has been used in cutting for hundreds of years. In the course of tool development, from the end of the nineteenth century to the middle of the twentieth century, high-speed steel was the main representative of tool materials; in 1927, Germany first developed cemented carbide tool materials and was widely used; in the 1950s, Sweden and The United States separately synthesized synthetic diamonds, and the cutting tools entered a period represented by superhard materials. In the 1970s, people used high-pressure synthesis technology to synthesize polycrystalline diamond (PCD), which solved the scarcity and high price of natural diamonds, and expanded the application range of diamond tools to aviation, aerospace, automobiles, electronics, and stone. And many other fields.
