Cubic Boron Nitride is one kind of superabrasives that has the most thermal stability and its hardness is only seond to be diamond. Not like diamond, due to the combination of CBN’s toughness, chemical and thermal stability, CBN is widely used for grinding ferrous alloys and superalloy materials. With many years of professional eperience, Besco developed K series CBN products covering all kinds of bond systems, offering the best choice for our clients.
Black color, irregular sharp, low toughness but good self sharpen ability, easily fractured monocrystalline. Widely used for resin bond systems and low temperature grinding.
Black, semi-tough,irregular, angular sharps increased grinding efficiency in resin or vitrified bond systems.
Black color,monocrystaline,semi-blocky, high toughness and thermal stability. Usually used for vitrified bond and metal bond, maintaining grinding performance and tool life.
Dark brown,irregular monocrystalline with sharp edge,tough and high thermal stability. Used in vitrified and metal bond systems, also used in heavy-duty resin bonds.
The combination of dark brown, irregular and sharp shape and high thermal stability provides high cutting efficiency and thermal stability. Suitable for vitrified bond and metal bond grinding wheels.
Gold color, blocky, very tough and very high thermal stability.Used in metal bond systems and electroplated tools.
Gold color, blocky. tough and high thermal stability,widely used in metal bond and electroplated tools,good choice for hardened tool steel, cobalt-based alloys and super cobalt alloy.
