    (54) Structure of a cylindrical grinding wheel for honing heads, particularly for stones, marbles, granite and the like


    (57) The present invention relates to a structure of a cylindrical grinding wheel for honing heads, particularly for stones, marble, granite and the like. The cylindrical grinding wheel (1) comprises a supporting element (2), provided monolithically, which extends around the axis of the grinding wheel (1). Said supporting element (2) defines an engagement seat (3), which extends coaxially with respect to the grinding wheel (1), for a wheel-bearing shaft of a honing head. The lateral surface of the supporting element (2) is furthermore rigidly coupled with the abrasive material (6) of the grinding wheel (1) which surrounds it.
