Introduction to CBN Inserts
CBN (Cubic Boron Nitride) inserts are cutting tools widely used in the machining industry. They are made from cubic boron nitride, a superhard material second only to diamond in hardness. CBN inserts offer excellent wear resistance, high thermal stability, and the ability to maintain sharp cutting edges even under high-speed and high-temperature machining conditions. These properties make them ideal for machining hard materials such as hardened steels, cast irons, and nickel-based alloys, significantly improving machining efficiency and product quality.
