ABSTRACT:
A grinding wheel is described which is bonded with a phenol formaldehyde resin based bond containing hexamethylenetetramine as the curing agent. The wheels are made by first wetting the abrasive with furfural in varying quantities relative to the amount of hexamethylenetetramine in the phenol formaldehyde resin. Different amounts of the curing agent require different specific amounts of furfural to produce optimum properties in the finished grinding wheel.
