Cubic Boron Bitride-CBN abrasive is knwon as the second hardest superabrasive material,cubic boron nitride is the ideal material to used in resin,metal,vitrified and electroplated bond CBN grinding tools for maching of steel, HSS tools and hard alloys.
Features of A00 grade CBN abrasive:
- Amber colored cubic boron nitride crystal
- Semi tough
- Irregular monocrystal shape
- Suitable for resin bond CBN tools like CBN grinding wheels,CBN polishing tools and CBN cutting tools.
