Cubic boron nitride cutting tools

Cubic boron nitride (PCBN) following the synthetic diamond hard appears after the second inorganic material, the hardness slightly inferior to diamond, thermal

stability, good heat resistance up to 1400 to 1500 degrees, the heat resistance than diamond Xing (700-800 degrees) is almost twice as high. cubic boron nitride

(PCBN) cutting tools is mainly suitable for processing a variety of ferrous metals and their alloys; most suitable for a variety of hardened steel (carbon tool steel,

bearing steel, tool steel, high speed steel) pearlitic gray cast iron (vanadium-titanium iron) chilled cast iron heat alloys (nickel base alloy cobalt-based alloys)

and surface coating

Surfacing processing. Has a long life, reduced number of tool changes, compensation down the time spent for NC machine tools and automated production line efficiency

can be more fully exploited, can change the traditional mechanical processing methods (ie, before quenching with a tool roughing and sand after quenching

Round finishing method), which can be in a CNC machine before quenching after quenching turning (turning instead of grinding), with good economic benefits.
