Definitions

  • the invention relates to a method for producing a grinding tool, which contains mutually distanced diamond particles, wherein recesses are provided on the surface of a powdered, sinterable matrix, in each of which a diamond particle is inserted before the matrix provided with the diamond pressed and finally sintered becomes.
  • the invention is based on the consideration that a lattice structure can be created on the surface of the powdery matrix from the material of the matrix itself. According to the invention it is thus provided that the recesses are formed by pressing a pattern into the powdery matrix.
  • the diamond particles are precisely fixed and thus remain in position both during the pressing of the powder and in particular during the application and pressing of another layer, so that an unambiguous assignment of the particles in different layers is ensured ,
  • Fig. 1 shows a schematic cross section of a device for separating
  • Fig. 2 is an enlarged detail of Fig. 1 represents.
  • Figs. 3 and 4 show the deposition of the Diamantgromer with the device of FIG. 1 and
  • An essential process step consists in the separation of the diamond grains, which are to be embedded in the segments of a grinding wheel.
  • the grains 4 are scattered on top of the perforated plate 1 shown in Fig. 1.
  • This perforated plate 1 is provided with holes 6 which are penetrated by pins 3, which are supported by a stamp plate 7.
  • a negative pressure is maintained, which propagates to the mouths of the holes 6, so that there is a grain 4 is held in each case.
  • the no hole 6 associated grains 4 are stripped or blown off.
  • the diamond grain is selected from the spectrum of 350 to 700 microns.
  • the holes 6 of the perforated plate 1 are larger in diameter (about 0.6 mm) than the average grain size, so that the grains 4 can settle therein.
  • a typical distance between the holes 6 is 1, 25 mm.
  • a first function of the pins 3 is that to prevent the laying of the holes 6 by smaller grains. Their main purpose, however, results from FIGS. 3 and 4.
  • the perforated plate 1 is pivoted through 180 ° and brought so close to the base 2 that no suction of powder from the base 2 occurs. If one simply dropped the bodies 4 out of the height thus caused, there would be no uniform arrangement of the bodies. This arrangement is facilitated when the bodies 4 are ejected by moving the die plate 7 in a suitable guide 8 by means of the pins 3.
  • metal powder is first poured or molded into a mold at a height of, for example, 2.5 mm to 3 mm. Subsequently, the powder layer is compacted by a waffle pattern of protruding truncated pyramid bearing stamp by 25% to a height of about 1, 8 to 2.2 mm.
  • the compacted powder Therefore, between webs 10, the distance of which, for example, 1, 25 mm, frustoconical depressions 5, whose bottom measures, for example, 0.3 mm square at a height of 0.4 mm of the truncated pyramid.
  • the material from which the pad 2 is formed corresponds to the prior art.
  • 56% of its alloy could be Cu-Co-Fe, 26% bronze (90% Cu, 10 Sn) and 18% copper.

Abstract

L'invention concerne un procédé de production d'un outil de rectification, renfermant des particules de diamant à distance les unes des autres, procédé caractérisé en ce qu'on forme, à la surface d'une matrice pulvérulente, frittable, des évidements, par insertion à la presse d'un modèle dans ladite matrice pulvérulente, évidements dans chacun desquels on insère une particule de diamant, avant que la matrice pourvue des diamants soit pressée et, pour finir, soit frittée.
