ABSTRACT:
An abrasive grinding wheel (1) is described which has a concavity (8) in the abrasive in which a metal ring (4) is embedded. The metal ring (4) is non-abrasive but is sufficiently hard to resist wear by rubbing against the material being ground. The grinding wheel (1) hence removes material only until the metal ring (4) encounters the summit of the convex shape obtained. The metal ring (4) therefore operates as a stop-rest which automatically prevents superfluous removal of material.
