Definitions

  • the invention relates to a method and a dressing roll, according to the preamble of claims 1 and 10, respectively.
  • a method and such a dressing roll are known from WO 00/06340 A.
  • a dressing roller consisting of a disc-shaped base body and arranged in a side surface of the main body annular circumferential recess arranged a variety of Abricht emotionsn such.
  • the Abricht stresses are at least partially disposed directly adjacent to a wall of the recess and / or the bottom of the recess, the spaces between the Abricht stressesn with each other and between the Abricht stressesn and an adjacent wall and / or the floor with a pourable or flowable matrix powder are filled and the spaces in the matrix powder with an infiltrant, in particular solder, are filled.
  • the infiltrant may be a standard solder, in particular a non-activated Kupferbasislot, so that the need for costly production material is low.
  • the matrix powder and / or the infiltrant can contain the wear resistance of the bond of the dressing covering-increasing admixtures, in particular carbide, nitride, oxide and / or ceramic powder or granules, so that a bond wear is reduced.
  • a compound of the diamond dressing bodies with the bond is produced by carbide formers, in particular tungsten, contained in the matrix powder and / or infiltrants, by chemical reaction during the infiltration process.
  • carbide formers in particular tungsten
  • the wear resistance of the bond and the bond strength e.g. B. by the choice of the appropriate materials to be matched to the requirements and the stability of the dressing body to be adjusted.
  • the orientation of the dressing body and the Abrichtbelages can be designed according to the arrangement and design of the groove at any angle with respect to the axis of rotation of the dressing roller.
  • the orientation of the dressing body and the Abrichtbelages can be designed according to the arrangement and design of the groove at any angle with respect to the axis of rotation of the dressing roller.
  • geometrically defined dressing bodies These may be positioned according to the arrangement and design of the groove in a vertical or parallel orientation to the axis of rotation of the dressing roll, but also any angular positions between the aforementioned orientations are possible.
  • At least some of the dressing bodies may be aligned at least partially perpendicular to the axis of rotation of the dressing roll, at least some dressing bodies may be aligned at least partially inclined to the axis of rotation of the dressing roll and / or at least some dressing bodies may be aligned at least partially parallel to the axis of rotation of the dressing roll so that the orientation of the dressing bodies is completely is specifically tuned to the particular application, which was not possible with conventional dressing rolls due to the binding mechanisms.
  • the dressing bodies can be at least partially distributed stochachstisch distributed and / or used orderly, but there are also other, especially irregular and / or random distributions possible.
  • the invention further relates to a method for producing a dressing roller, consisting of a disc-shaped base body and an annular peripheral, a plurality of Abricht emotionsn such.

  • the object of the invention is to avoid the aforementioned disadvantages and to provide a simple, less expensive and less expensive way to produce dressing rolls of the aforementioned type.
  • the machining is cheaper, since the usually made of steel body can be processed easier than the otherwise at least a substantial part of the dressing roller to be processed forming binding material of matrix powder and infiltrant.
  • the dressing roller can also be brought into a desired shape by further removal of material from the base body and / or Abrichtbelag.
  • the matrix powder can be compacted prior to filling with the infiltrant, in particular by shaking and / or spinning and / or vibrating, so that the spaces to be filled are reduced and the need for infiltrant required for filling is reduced, whereby the production costs are further reduced. Also, due to the high density thus produced, the dressing bodies are held in position even with the removal of the adhesive effect of the adhesive, so that no difficult to process and laboriously applied high-temperature adhesives are required.
  • a standard solder in particular a non-activated copper base solder
  • a low-cost forming gas for shielding the air atmosphere is sufficient, and the production does not have to be carried out in a high-purity inert gas, in particular inert gas atmosphere or in a high vacuum, whereby the production costs can also be significantly reduced.
  • the matrix powder and / or the infiltrant can contain the wear resistance of the bond of the dressing covering-increasing admixtures, in particular carbide, nitride, oxide and / or ceramic powder or granules, so that a binding wear can be minimized.
  • the connection between the diamond dressing bodies and the bond is produced by carbide formers, in particular tungsten, contained in the matrix powder and / or infiltrants by chemical reaction during the infiltration process.
  • carbide formers in particular tungsten
  • an optionally electrically conductive one- or two-component adhesive with a long processing time can be used as the adhesive, so that a careful prefixing of the dressing bodies can be carried out without problems.
  • the dressing bodies may be aligned at least partially perpendicular to the axis of rotation of the dressing roll, but at least some dressing bodies may be at least partially aligned with the axis of rotation of the dressing roll and / or at least some dressing bodies may be aligned at least partially parallel to the axis of rotation of the dressing roll Dressing rolls due to the binding mechanisms was not possible.
  • the orientation of the dressing body can be tailored specifically to the particular application.
  • the dressing body can be at least partially distributed Stochachstisch as well as ordered or used in combination of these arrangements.
  • Fig. 1 shows a first embodiment of a dressing roll 1 according to the invention, which consists of a base body 2, which has an annular circumferential groove 3 for the Abrichtbelag 4.
  • dressing bodies 5 e.g. Diamonds in the form of natural diamonds, synthetic, poly or monocrystalline diamonds, arranged, which are prefixed by an adhesive, not shown in the drawing.
  • the free spaces 6 between the Abricht stressesn 5 with each other and between the Abricht stressesn 5 and the adjacent walls 7 of the groove 3 are filled with a pourable or flowable matrix powder 8.
  • a liquefiable infiltrant 9 in particular as a solder in the form of granules, powder, paste or pieces. This is melted In particular, due to its capillarity, it also fills in the gaps in the matrix powder 8 (see FIG. 3).
  • base body 2 and matrix powder 8 are materially connected to each other and the dressing body 5 are incorporated in addition to the chemical compound form fit.
  • the dressing body 5 After solidification of the infiltrant 9, the dressing body 5 are exposed in a mechanical manner by removing material of the base body 2.
  • the groove 3 is reduced by omitting a groove wall 7 to a recess 3a with recess wall 7a and recess bottom 10a.
  • the dressing roller 1 can be brought by further removal of material from the base body 2 and / or Abrichtbelag 4 in a desired, tailored to the specific application form.
  • FIGS. 5 to 7 show different production phases of a further embodiment of a dressing roll 1 according to the invention, in which the groove 3 has a pre-machined profile radius 11.
