Definitions

  • the present invention discloses a tool for surface roughing, in particular for flooring, of the type consisting of a support to be applied to a machine and of a layer made of an abrasive material fixed to such support, where the abrasive member consists of several diamond sectors fitted onto said support and buried into a mass of soft material, especially rubber.
  • This configuration allows obtaining a tool capable of effectively machining the surface, performing an effective abrasive action without having these sectors damage the edges of ceramic or similar tiles.
  • the mass of soft material where the diamond sectors are buried serves as a protection to prevent them from scratching the edges of the tiles or slabs forming the flooring, but allowing the diamond to scrape the surface quite deeply.
  • the invention relates to the field of equipment for surface finishing tools, and in particular it relates to equipment for finishing flooring and the like.
  • the machines used to this purpose are provided with a rotating member to which tools such as abrasive grinders or the like are applied, and which are placed into rotation laying against the material to be machined to perform roughing, smoothing and polishing.
  • these machines comprise a frame mounted on wheels, and an electric motor that actuates a rotor with substantially vertical axis, to which a plate supporting several tools is applied.
  • the tools consist of sectors made of an abrasive material, according to the type of finish to obtain.
  • large grain abrasive sectors are used, capable of removing a certain amount of material from the flooring, so as to level and smooth it.
  • These tools may exhibit a continuous surface, for example consisting of a plane disc or grain with circular crown, or of a series of sectors mounted one next to the other, onto a generally circular support.
  • the tools consisting of more sectors sometimes exhibit disadvantages since if the operation is performed on a flooring consisting of tiles, stone slabs or the like, the sectors that rotate and strike against the edges of protruding tiles may chip or damage them.
  • the present invention can be framed in this field, as it discloses a tool capable of solving the problems mentioned above and which consists of several diamond sectors fixed to a yielding support and buried into a layer of soft material, for example rubber and the like, which prevents the sectors from hitting against edges and corners of tiles, but which allows an effective surface roughing action, thanks to its elasticity and deformability features.
  • the tool according to the invention comprises a support 1 suitable to be applied to a roughing/smoothing/polishing machine, an intermediate layer 2, and a tool, globally indicated with reference numeral 3, consisting of a support 4 to which several abrasive sectors 5 are fixed.
  • Support 1 made of a resistant material provided with couplings for the application to a machine not shown in the figure, is made of metal, preferably of aluminium.
  • the intermediate layer 2 consists of a layer of deformable material, in particular vulcanised rubber, applied to support 1 by a layer of anchoring material, schematically shown in the figure and indicated with reference numeral 6.
  • Such intermediate layer made of soft and deformable material, is to allow the tool to slightly bend or, in any case, to follow and adjust to the unevenness of the surface to be smoothed.
  • the active part of the tool consists of several sectors made of an abrasive material 5, preferably arranged as dial and fixed to a support made of resistant material sufficiently flexible to follow the deformation of the intermediate layer of vulcanised rubber.
  • such support layer consists of a grid or a drilled plate or the like, to which sectors 5 are welded.
  • Sectors 5 consist of an abrasive material, preferably diamond powder mixed with a metal binder, preferably a bronze- or cobalt-based alloy.
  • the support layer 4 must be shaped as a grid or drilled since, according to a feature of the invention, the diamond sectors 5 are embedded into a layer made of a soft and deformable material, preferably a vulcanised rubber layer, which is then applied and made to adhere to the intermediate vulcanised rubber layer 2.
  • a soft and deformable material preferably a vulcanised rubber layer
  • the holes in the support plate 4 are therefore intended to allow this material to move to the opposite side and totally incorporate the support plate with the abrasive sectors.
  • the sizes and amounts of diamond powder contained in the alloy may change based on the type of operation required.
  • the sectors produced had plan dimensions of 24 x 10 millimetres and a height of 10 millimetres, and they were welded to a support consisting of a plate with an approximate thickness of 2 mm.
  • This tool was applied to an aluminium support with a vulcanised rubber layer with a thickness from 4 to 6 millimetres arranged in between.
  • the tool according to the invention is especially convenient to use since there is no risk of chipping floor coating tiles, as the hollow space between a pair of close sectors is filled with soft material, in particular vulcanised rubber, which has the dual function of totally filling the gaps between diamond sectors, thereby preventing them from hitting and damaging the side edge of tiles during rotation, and of serving as deformable support that allows the tool to tilt and adapt to any unevenness existing on the material to be smoothed.
  • soft material in particular vulcanised rubber
