What Is CBN Grinding Wheels?
CBN (cubic boron nitride) grinding wheels are a type of abrasive product that is commonly used in the manufacturing and metalworking industries. They are made from a compound of cubic boron nitride particles and a bonding material, which is typically resin, ceramic, or metal. CBN is a superhard material that is second only to diamond in terms of hardness, making it ideal for grinding applications.
CBN grinding wheels offer several advantages over traditional grinding wheels. Firstly, they have a much higher cutting ability, allowing for faster material removal and reduced cycle times. This makes them particularly well-suited for grinding hard materials such as hardened steels, superalloys, and cast iron. Additionally, CBN wheels retain their shape and size for a longer period of time, resulting in greater consistency and accuracy in the grinding process. They also generate less heat during use, reducing the risk of thermal damage to the workpiece.
