<p>The present invention concerns a rotating head for grinding machine. This is used, in particular, for the polishing of marble, granite and stone material in general. More precisely, it refers to a rotating head 1 with a plurality of tool holding sectors 31, each of which has at the bottom an abrasive tool 32 and is connected to a support 30 which rotates with ability to oscillate relative to the latter. The rotating head has, associated with each tool holding sector, a toothed wheel 21 connected to a cam element 40 which is coupled to the particular tool holding sector to make it oscillate relative to the support. <IMAGE></p> |
