TNGN 160404 CBN Turning Insert 6 Corner For Cast Iron Turning HRC< 60

CBN (cubic boron nitride) is second only to diamond in hardness. CBN is a synthetically produced material for stable machining due to its high thermal conductivity. High hardness results in superior wear resistance and long tool life. High-speed cutting is applicable to heat-treated steel and cast iron. Heat conductivity is good, and prompt heat evacuation and stable cutting are possible. Since it was first introduced as a cutting tool material in the 1980s, the use of cubic boron nitride (CBN) has evolved to become a common machining solution. The application areas include hardened steels, cast irons, heat-resistant superalloys (HRSA), and powdered metals. These workpiece materials have one thing in common; they are generally recognized as being difficult to machine. A CBN insert can withstand the high cutting temperatures and forces and still retain its cutting edge. This is why CBN delivers a long, consistent tool life and produces components with an excellent surface finish.
