CBN inserts are the super hard cutting tools, second to PCD inserts. CBN bears a higher decomposing temperature than PCD. It’s an excellent choice for machining ferrous materials such as alloy steels and cast iron, which are unsuitable for PCD tools because of less chemical resistance to ferrous materials. The sharp cutting edges and low friction rake assure high-quality surface finishes. High speed reduces machining time drastically. Welcome contacting for OEM projects.
