Abstract (en)
[origin: EP0257013A2] The mechanical grinding and/or polishing of a glass surface (1) is advantageously effected with the aid of a frustoconical or toroidal grinding wheel (4) provided with an annular band (3) of abrasive material mounted off-centred with respect to an axis of rotation (5) of the grinding wheel (4). The axis (5) is inclined with respect to an axis of rotation (2) of the surface (1) to be treated, so as to apply the said grinding wheel (4) along a contact generatrix (7) against the surface (1) to be polished under a specified pressure (Figure 1). <IMAGE>
