An apparatus for making abrasive articles, e.g., wheels, disks and the like abrasive particles wherein a train of the particles is displaced along a transport path and means is provided for automatically detecting the crystallographic orientation of the individual particles. Particles of appropriate orientation are withdrawn from the transport path and carried with fixed orientation to the wheel, disk or other substrate into which it is implanted. The individual particles are set in predetermined locations of the disk whose motion is governed by numerical control means.
