Definitions

  • the present finding concerns a diamond-tipped cutting disc, according to the general part of claim 1.
  • cutting discs In the stone and ceramics industry cutting tools identified with the term "cutting discs" and used for cutting or chamfering different products, from natural stones to ceramics, from granite and marble floor tiles to single fired products and from fine compact clinker bricks to hard porcelain stoneware, are regularly used.
  • a cutting disc for so-called “diamond” cutting, consists of two parts: a disc: defined with the term “core”, made from steel, equipped with a central hole for adapting to the operating machine and a diamond band, defined with the term “ring”, applied onto the outer circumference of the core, which constitutes the cutting member.
  • the diamond band is applied onto the steel core to form a single body, through different operations, from braze welding to the use of laser welding.
  • Cutting discs are split into two categories: continuous band or crown discs and sector discs, corresponding to the different configuration of the diamond band, respectively consisting of a single ring or of a plurality of radial plates, arranged on the outer circumference of the steel core and arranged more or less close together.
  • cutting discs are designed and made that, suitably combining the constructive parameters of the tool such as the type of grain of the abrasive part, the diameter, the thickness and the height of the diamond band, aim to obtain the best possible yield in terms of material worked.
  • the purpose of the present finding is that of making a diamond-tipped cutting disc that, during use, displays properties, such as greater resilience, elevated hardness, substantial abrasiveness and low wear, such as to make it, during use, highly innovative with respect to similar known products and very economically advantageous.
  • Such a purpose is obtained by making a diamond band that has the two side walls that, instead of being flat, as it is in current product, are equipped with shaped ridges that constitute the abrasive surface of the tool.
  • such ridges consist of surface portions that are arranged, with modular progression, circumferentially and that extend on an entire or both side walls of the diamond band.
  • Such ridges are obtained through recesses that, substantially, can be grouped into two types of configurations: circumferential rings, arranged concentrically on the side wall of the diamond band and a plurality of plates, arranged substantially transversally with respect to the circumference of the aforementioned rings.
  • the plates are arranged rectilinear to each other, with directions that are preferably radial or lying on lines tangent to a concentric and inner circumference with respect to the circumference that constitutes the outer perimeter of the aforementioned band, i.e. with the outer perimeter of the cutting disc.
  • the ridges can have the sides straight or, preferably, inclined, so as to make sections diverging towards the outside and the plates, moreover, can be shaped with a circular and/or in any case polyhedral outer profile.
  • the "polishing" and “greasing” effects of the abrasive ring are substantially delayed and, in wet cutting, they advantageously cause the cooling water cushion that forms on the work surface to be broken.
  • a so-called diamond-tipped cutting disc wholly indicated with reference numeral 1, consists of a central disc or core 2 made from steel, equipped with the hole 3 for the attachment to the machine tool and the diamond band or ring 4, welded on the outside.
  • the ring 4 made from a known abrasive material, is characterised in that its side surface 5 is equipped with shaped ridges 6 that, when in work, help the cutting operation, constituting in themselves the abrasive surface of the disc.
  • the shaped ridges wholly indicated with reference numeral 6 and projecting from the wall 5, comprise plates 8.1, with circular profile, contained inside the border rings 7.
  • the shaped ridges wholly indicated with reference numeral 6 and projecting from the wall 5, comprise rings 7, arranged circumferentially and concentrically on the wall 5, which intersect the plates 8.2, with a substantially quadrilateral profile.
  • a third embodiment is obtained in which, thanks to the mutual interference between the rings 7 and the plates 8.1 and 8.2, an abrasive surface 5 is obtained equipped with shaped ridges 6, which allow a substantially advantageous cutting action such as to completely satisfy all of the processing requirements required for cutting and chamfering all types of stone and ceramic materials.
