When machining high-speed steel Roll, our IBN600 CBN turning insert can achieve the geometric accuracy of the Roll and ensure the machining life of the tool.

High speed steel rolls are commonly used to cast high speed steel. High-speed steel for Rolls has a carbon content of about 2%, a low tungsten content, less 

than 10%, a high chromium content of 10%-20%, and a high vanadium content, generally 5%. Known as high carbon high vanadium high speed steel. The Roll 

surface made of high speed steel is high speed steel, and the core part may be ductile iron or structural steel.
