Vitrified Bondings and Superabrasives

What is a Vitrified Bonding System?

Vitrified bonds are the most recently developed and advanced bonding systems for superabrasive grinding wheels. The bondings themselves are composed of sintered glass and are initially mixed in powdered form along with the CBN or Diamond abrasive. Each component of the mix is precisely determined by the required characteristics of the final wheel. After pressing to shape, the vitrified bonded wheels are fired in a high-temperature kiln. Unlike other bonding systems such as resin or metal, the resulting bond structure is both very porous and very wear resistant.

This unique combination of porosity and toughness makes vitrified bonded wheels ideal for:

• high stock removal rates.
• difficult to grind materials.
• applications where maximum wheel life is desired.
• applications where corner and form holding are critical.

The “self-dressing” nature of vitrified bonded wheels also allow truing and dressing to become one operation, eliminating the need for stick dressing altogether in most applications.  Therefore, Vitrified Bonded wheels are ideally suited for high-production CNC grinding applications.

Whether you’re grinding 1 part or 1 million parts, vitrified bonds are the ideal choice!
