Difference between tungsten carbide tools and superhard tools
Nov 12, 2018

Tungsten carbide, also known as cemented carbide, has a series of excellent properties such as high hardness, high strength, good excellent wear resistance and corrosion resistance. Carbide is widely used as a tool material, such as turning tools, milling cutters, planers, drills, boring tools, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and ordinary steel, can also be used for cutting Hard-to-machine materials such as heat-resistant steel, stainless steel, high manganese steel, and tool steel.

The chemical composition of superhard materials and the hardness of their formation are different from those of other tool materials. Cubic boron nitride is a non-metallic boride with a crystal structure of face-centered cubes; while diamond is converted from carbon, its crystal structure and cubic nitrogen Boron is similar. Their hardness is much higher than other substances.

Superhard tool materials, especially diamonds, come in many varieties. Cubic boron nitride has CBN single product powder for making abrasive tools; PCBN poly wafer and PCBN polycrystalline composite sheet for making tools and other tools.
