ABSTRACT:
Broadly, the present invention comprises substantially spherical glass globules encapsulating an abrasive particle. The globules are suitable for incorporating into a vitreous bonded grinding wheel and can be made by the steps comprising forming a mixture of glass powder, abrasive particles, and a fluent binder. The binder is fused to form a solid mass containing said glass powder and abrasive particles. The solid mass then is attrited into discrete particles. A desired size fraction of particles of the attrited mass then is separated from any undersize and oversize particle fractions. Finally, the desired size fraction is heated to fuse the glass particles into substantially spherical globules which encapsulate one or more of said abrasive particles. The globules are suitable, then, for incorporation into vitreous bonded grinding wheels.
