    Ceramic CBN grinding wheel for grinding rotor

    As key equipment in modern energy conversion and power systems, turbines require extremely high precision and quality in their manufacturing and maintenance processes. The grinding of turbine rotor grooves is one of the important processes, which directly affects the performance and life of the turbine. In recent years, ceramic CBN (cubic boron nitride) grinding wheels have gradually become an ideal choice for grinding turbine rotor grooves due to their excellent hardness, wear resistance and thermal stability. This article will explore the application and advantages of ceramic CBN grinding wheels in turbine rotor groove grinding.
