CBN insert for turning, a kind of superhard cutting tool, is made of CBN micro powder with ultra-high temperature and high pressure technology under the action of a small amount of binder. Because the hardness of CBN tool is very high, it is very suitable for processing materials with hardness greater than HRC50 and strong wear resistance.

CBN hard turning insert can be used to cut hardened steel (bearing steel, die steel, etc.), cast iron (gray cast iron, nodular cast iron, high chromium cast iron, alloy wear-resistant cast iron, etc.), high-speed steel, cemented carbide, superalloy and other materials, and have great advantages in ferrous metal processing.

It should be noted that if the processing material is soft family metal or non-metal, it is not suitable to process with CBN tools. CBN tools are recommended only when the material hardness reaches a certain level (HRC > 50)

The CBN turning and milling insert produced by our company can easily be used for hard turning application; especially WNMG CBN insert for rough and semi-finish machining of steel roll is widely used by customers. For finish operation, we can provide CBN wiper insert.
