Vitrified bonded CBN grinding wheels

The CBN vitrified grinding wheels show a significant superiority in high efficiency grinding processes when compared to conventional wheels. The physical properties of CBN (hardness, abrasion and high temperature resistance) in connection with vitrified bond properties (hardness, brittleness, porosity structure) allow to machine a more aggressive piece with great capacity and to achieve a high grinding productivity.

CBN tools are used for grinding such hard-to-process materials as:
hardened high speed steels (HSS);
- chrome steels;
- bearing steels;
- stainless steels with hardness >55HRC;
- stellite.
