Definitions

  • the present invention refers to a perfected apparatus to grind the surfaces of pieces of stone or similar materials.
  • the grinding apparatus for the surfaces of stone or similar materials is formed by a support, preferentially discoidal, placed parallel to the face or surface to he ground, and also on the lower side of the support pieces are attached appropriately to make some perforations made in the support coincide with drillings made in the said pieces, holding them with screws.
  • One of the novel characteristics of the invention consists in the discoidal support having some holes at 30° between each, that is, the drill holes are on ideal radii at 30° between each and also at a variable central distance from each other to achieve maximum operability.
  • Each part holding the roller has a "U" section in which the central branch has a hollowed out area on its inner face and perforations on each side to which are attached the screws that allow attachment of the piece to the discoidal support.
  • Every 60° on the supporting part are holes that serve to attach the part to the rotating head of the corresponding machine and then every 60° pairs of holes appear on the same radius, with a position that varies sequentially from the centre in order to cover the maximum surface with the smallest angle of the rollers, and to do this they are placed at different distances from the centre and also in different directions.
  • the apparatus 1 is formed by a discoidal part 2 that has holes in a radial direction every 30°. Of these holes some are shown every 60° with number 3 and these are used to hold the part 2 to the rotating head of a machine, not shown.
  • the holes marked with number 4 are those placed on 60° radii in pairs at an equal distance but placed at different points on their radii.
  • Each axle has on its ends two sets of: a brass or bronze bushing 10, a plastic cap 11, a holder 12 placed in the groove 13 of the roller and a ball bearing 14.
  • Each roller 6 has a perimetral edge with small portions 5 of very hard metallic carbon, which grind the surfaces which are not shown.
  • each "U" shaped piece 5 On the interior face 16 of each "U" shaped piece 5 is a straight hollow 17 of a width similar to the edge of the parts 15, to avoid scraping against them.
