A Cubic Boron Nitride (CBN) wheel is a type of grinding wheel made from a synthetic material known for its hardness and thermal stability. CBN is second only to diamond in terms of hardness, making these wheels ideal for grinding hard materials like steel and carbide. They are commonly used in industrial applications for precision machining and tool sharpening. CBN wheels are favored for their ability to maintain sharpness and resist wear over time. Unlike traditional abrasive wheels, they do not generate excessive heat during grinding, which helps preserve the integrity of the workpiece. This makes CBN wheels a popular choice in manufacturing and metalworking industries.
