Methods for orienting fibers and an apparatus for orienting fibers are provided for the fabrication of improved thin abrasive wheels utilizing uniform non-woven fiber reinforcement discs. The wheels are more resistant to hub push-out failure during grinding than wheels reinforced with woven fiber cloth.

Bonded abrasive products comprising alumina-based abrasive grains and a geopolymer bond system are significantly improved by providing the grain with a vitreous coating before incorporation in the geopolymer bond.

Abrasive tools and a grinding process are for use in the manufacture of hypodermic needles. In particular, a formulation including selected bond components, and a process for manufacturing grinding wheels having an embrittled bond permits a new method for grinding of fine hollow metal tubes to shape the tips of hypodermic needles with the substantial elimination of metal burrs or fines from the grinding process.

Uncured molded abrasive articles having low volatile organic chemical content are prepared using water as a temporary binder. The abrasive articles preferably contain a uniformly coated abrasive grain comprising a novolac resin having a phenol:formaldehyde ratio of 1:0.2 to 1:0.35 and containing less than 0.5% free phenol.
