Boron Carbide, or B4C, is an extremely hard ceramic material discovered in 1899. With a Mohs hardness between 9 and 10, boron carbide is one of the hardest synthetic substances known, being exceeded only by cubic boron nitride (cBN) and diamond. Besides, it has good chemical inertness and high neutron absorption cross section.
High purity and high-performance pyrolytic boron nitride ceramics are used as the substrate for the PBN heaters. Pyrolytic graphite (PG) is placed on the surface of PBN plates by the CVD method as conductor and heater. Depending on the different requirements of applications, the PG heating element could be covered by PBN again or just stay open.
solid corner cbn inserts have good heat absorption capacity, superior solderability and resistance to soldering heat, but solid corner thoroughly brazed cbn inserts have better impact resisrance, mainly for interrupted and heavy interrupted machining. each solid corner equals to two cutting edges when comparing with the tipped cbn inserts.
