PCBN is shortened from Polycrystalline Cubic Boron Nitride.
PCBN inserts are made from PCBN as row material, through cutting,
brazing, grinding and production processes. PCBN inserts are always
used for finish and min-finish machining ferrous metal, including
cast iron, hardened steel and other hard wearable material. PCBN
inserts always perform perfectly when machining the above material.
Using PCBN inserts, you can get a high degree of finish of the
workpiece surface, even can achieve that replacing grinding with
turning. Meanwhile, PCBN inserts have much longer service life than
normal carbide cutting tools, so that PCBN tools can cut down the
production cost distinctly. PCBN tools can stand quite high cutting
speed with the stable performance therefore improving production
efficiency.
