Definitions

  • the present invention relates to a method for making tools.
  • the invention is advantageously used to produce tools suitable for performing various types of processing, such as roughing, smoothing, lapping, polishing or equivalent treatment, on materials such as natural stone, cement, glass, metal or laminated surfaces, agglomerates and composite materials in general, such as Bretonstone® or Terastone®, the description that follows will make explicit reference to without losing its generality.
  • the object of the present invention is to provide a method for making tools of various shapes and sizes, chosen according to specific requirements of the field of use and/or of the end user.
  • Another object of the present invention is to provide a method for making tools defined by various types of materials combined with each other, and with optimal surface finishes and increased machining efficiency.
  • thermoplastic, thermosetting or equivalent polymeric material and and a loose material (powder) with abrasive properties such as diamond, carbides, alumina, mineral fillers, metal materials in general to be mixed together with said polymeric material in order to obtain a filament containing a resin/polymer matrix with abrasive properties to allow use with a smoothing and/or polishing function that, in particular, emphasizes the features of the processed materials creating abraded surfaces of more or less intense colour tones, and eventually obtaining "anti- finger” (elimination of fingerprints created with the contact between the fingertips of the operator's fingers and the material itself) or "gloss/matt” (polished and opaque points) effects, more or less balanced between them but always without the typical defects of repetitive mechanical processing (e.g. sense of rotation); and
  • the methodology also provides for a subsequent baking step (post-curing) of said tool thus produced in order to consolidate/harden the thermoplastic polymeric material of which the tool itself is made, or free sintering step, in order to compact the molecules of the same tool, also removing any polymeric additives previously added to favour the aforementioned 3D printing step (in the case of metals).
  • tools that have a base called “support”, made of neutral material, that is without the addition of an abrasive part, an abrasive part made of a thermoplastic rubber matrix, and an abrasive part made of a matrix of a different type, such as, for instance, nylon or similar materials.
