Abstract (en)

The grinding wheel is made from particles of one material, with a grain size of 0.2-10 mm and, preferably, 0.2-3 mm, distributed randomly in a matrix of a second material. This second material is a thermosetting resin or a metal coated with a binding agent based on a thermo-setting resin. The particles forming the first material of the grinding wheel can be of a metal coated with a thermosetting resin binding agent, with the metal comprising 20-90 per cent, and preferably 50-65 per cent of the weight of the particles. The particles themselves represent between 2 and 40 per cent, and preferably 3-20 per cent of the weight of the grinding wheel. The metal can be, for example, chrome, iron, stainless steel, nickel, copper, titanium oxide, zinc, antimony, aluminium, tin or lead, and the thermosetting resin in the binding agent can be a polyester, epoxy or polyurethane resin.
