We’re experts and innovators focused on solving challenges, embracing change and growing.
Our specialty glass frits are used to create vitrified bonds needed to embed and bind abrasive grains together in superabrasive grinding wheels. Our glass frits impart excellent wetting behavior along with free-cutting behavior when precision grinding ferrous materials such as hardened steel or nickel-based alloys.
Superabrasive grinding wheels made with vitrified bonds are specifically designed to provide extremely strong adhesion to the cubic boron nitride grain through a strong ceramic bond, enabling G-ratio (volume ratio of stock removed to wheel wear) values of 10,000 or more. This ceramic bond strength can be varied by controlling the temperature and blending our specialty glass frits which allows our customers to tailor the ceramic to the superabrasive conditions and needs.
Additional property modification can be achieved by using a ceramic-coated grain offered by Superabrasives.
