Vitrified wheels

There is a great demand for special bonded wheels that are harder than both resin and metal bonded wheels, for the use in automated equipment and systems, which both resin and metal bonded wheels will not suffice. These highly demanded bonded wheels must be durable with extended life and be self-truing and self dressing in order to sustain maximum 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 to provide maximum performance with minimum performance with minimum maintenance.

Since the late 1980’s, EHWA® has developed high quality vitrified-bonded CBN wheels for grinding auto-parts, such as constant velocity ball joints. Thereafter, EHWA expanded the development of vitrified-bonded wheels for many different applications such as for grinding high precision machine parts, bearings, gears, tools and dies, semi-conductors, ceramics, cermets, and in particular, cutting tools fabricated out of PCD or PCBN.

Today, the demand for vitrified-bonded wheels is sharply increasing in various high-tech industries. EHWA® has put forth its best efforts to develop better quality and highperformance vitrified-bonded products to meet all diversified industrial applications.
