Application of Boron Nitride Polycrystal in Metal Cutting Field

Cubic Boron Nitride Cutting Tools are a kind of superhard material product that are formed by the coalescence of many fine grains (0.1~100 micron) CBN. In addition to high hardness and abrasion resistance, it also has the characteristics of high toughness, chemical inertness, red hardness, etc., and can be polished with the cutting edge of the diamond grinding wheel. It shows excellent cutting performance in all aspects of machining and can achieve stable cutting at high temperatures, so it is especially suitable for machining all kinds of hardened steel, tool steel, chilled cast iron, and other hard-working materials with high hardness.

PCBN has most of the properties of CBN, and overcomes the disadvantages of directional cleavage of CBN single crystal surface, and has many performance advantages.
