Abstract (en)
Apparatus to grind the surfaces of stone or similar materials; formed by: a discoidal part (2) with perforations (3) set at 60 DEG to each other to attach (2) by screws to a rotating head of a machine, while at 60 DEG and sequentially and set radially there are pairs of notes with an equal distance between each pair but each pair at a different distance from the centre, to which are attached "U" shaped parts (5) placed on the parallel branches of the notes on which is mounted the axle of a roller (6) with elements that aid in the centering and rolling on the same, appearing on the central branch of each "U" shaped part (5) and on the inside face, a straight undercut of approximate width that holds a perimetral edge on each roller (6) on which are held small portions of a metallic carbon material sufficiently hard to grind the surface of the piece of stone. <IMAGE>
