is great demand for superabrasive wheels that have the durability
of metal bonds but the free cutting action of resin bonds.
These wheels must be durable with extended life and be self-truing
and self-dressing in order to provide performance over long
periods of heavy use.
Vitrified-bond technology is today's answer. A vitrified
bond is actually a ceramic bond. It is extremely hard, yet
free cutting, and combines the better characteristics of
both resin and metal bonds. It provides a longer tool life,
effective grinding, and high productivity, which provides
maximum performance with minimum maintenance.
