CBN inserts are used in the roll processing industry widely




With the development of science and technology, there has been a major breakthrough in the manufacturing technology of PCBN inserts, which has been in the heavy-duty cutting and intermittent cutting industries, It is widely used in hardened steel, high alloy cast iron, high speed steel, tungsten carbide alloy, and Its also widely used in super hard materials such as nodular cast iron, gray cast iron, high manganese steel and alloy steel.
 


   
The application technology of PCBN inserts is constantly maturing, and people's understanding of cubic boron nitride monolithic polycrystalline(PCBN) has undergone important changes.


 
 
PCBN inserts/CBN inserts (Here we mean solid CBN inserts) are used in the roll processing industry: (rough turning, finishing turning)
