Solid CBN Inserts for Turning White Cast Iron

The main material of the slurry pump casting is high chromium cast iron (Cr26), which is the main alloying element of high chromium cast iron. It contains 

26％-28％chromium and hardness HV1200-1800. The hardness of high chromium cast iron is high, which leads to the general tool, such as Ceramic inserts, 

difficult to cut machining problems. Our products are capable of high-speed interrupted cutting, no matter how bad the processing conditions and how difficult 

the processing conditions are.
