Definitions

  • the present invention relates to diamond pellets with which circular saws intended, in particular, for cutting granite.
  • pellets are made up of a mixture of diamond and binder, in principle in the form of a metallic powder, such as cobalt. They are obtained by compacting and sintering at high temperature and are welded to the periphery of circular discs, or sheets, of large diameter and small thickness.
  • pellets made of a single element in a mixture of given diamond concentration rapidly deformed and their cutting surface was rounded, causing deviations of the cutting disc and non-planar cutting surfaces.
  • the pellets according to the invention avoid any deformation at the time of the attack and consequently any deformation of their surfaces.
  • the cut is then of excellent quality, that is to say of perfect flatness, the pellets wear regularly and the sheet or disc, cutting sees its longevity significantly increased.
  • the circular saw is constituted by a disc, or sheet metal, 1 with a thickness of 9 mm and for a diameter of 2.5 meters, at the periphery of which are welded diamond pellets 2 of 15 mm. height, 35 mm in length and 12 mm in width.
  • These pastilles 2 of shape which widens slightly towards their free face consist of five parallel elements 3, 4, 5, 6 and 7 of different widths, obtained by mixing a binder, such as cobalt, with diamond powder or granule.
  • the diamond concentration of the intermediate elements 4 and 6 is lower than that of the middle elements 5 and external elements 3 and 7.
  • the width of the central element 5 is substantially double that of the external elements 3, and 7.
  • the saw therefore exerts a grooving effect in the median plane of the sheet 1, which prevents any deformation on attack and therefore on the cutting surfaces of the pellets.
