CBN blade for NC machining of carburized and quenched steel 20Cr

20Cr carburizing and quenching is a common heat treatment process for 20Cr metal materials. It can make the carburized 20Cr workpiece surface obtain high hardness and improve its milling operation wear resistance. The steel parts after carburizing and quenching have high hardness, generally above 55 degrees

The hardness of

20Cr material increases after carburizing and quenching, which is difficult to process with ordinary tools. The first three kinds of tools are only suitable for machining quenched parts with hardness below HRC55 degrees. For the hardened steel parts after carburizing and quenching, the cubic boron nitride car blade with higher hardness and better wear resistance also needs to be selected
