<p>A grinding wheel is described, particularly for grinding work at a high feed speed, comprising a discoid body (2) between the axially opposed faces (2a, 2b) of which an outside wall (4) of cylindrical profile is defined, bearing the abrasive grinding material, and wherein the abrasive material is disposed circumferentially on the outside wall without a gap. The grinding wheel also comprises a plurality of ducts (7) extending radially in the discoid body (2), opening onto the outside wall (4) and also passing through the abrasive material, so as to constitute ducts for conveying a cooling and/or lubricating liquid onto the abrasive outer surface of the outside wall.</p> |
