RNGN Solid CBN Inserts for Impeller Pump Machining

The slurry pump is widely used in mining, electric power and other industries. The impeller is the core component of the slurry pump. Its quality is related to the service 

life of the slurry pump. Our PCBN Inserts are capable of high-speed interrupted cutting, no matter how bad the processing conditions are.
