Procedure for the manufacture of abrasive particles (1) of abrasive grains (3) in particular grains of diamond or cubic boron nitride kept together by a metal phase (2) which may be used for instance in resin bonded grinding wheels. A blank is made of the abrasive grains and a bonding agent consisting of metal or a metal alloy whereby a continuous network is formed in the blank by addition of a pore forming material (4). The abrasive particles are then obtained by disintegration of the blank. |
