Abstract
The invention provides a method of making an abrasive product, e.g. a grinding wheel rim, which consists in providing a mixture of needle-shaped abrasive particles and the starter ingredients for a bonding matrix, causing the mixture to flow, preferably in a passage having a constriction, so causing the particles to orientate with their long axes substantially in the direction of flow, and allowing the mixture to set, at least partially.
