Definitions

  • the invention relates to a dressing tool which comprises a base body with a working surface and distributed on this work surface arranged hard material grains.
  • Such a tool is in the document EP-A-2 535 145 revealed.
  • the tool described there is used in particular for dressing grinding wheels or grinding worms for grinding gears and similar components.
  • an adhesive with a defined film thickness is applied to the working surface of the tool to be produced, and then the hard material grains are applied to the working surface provided with the adhesive, where they remain permanently bonded as particle coating after the adhesive has cured.
  • the invention has for its object to provide a dressing tool and a method for its production, in which the main body of the tool occupied with an improved distribution of the hard grains and with it thus an optimization of his work surface is achieved in terms of its cutting action.
  • depressions for receiving the hard material grains are introduced into the base body, the geometry of which is adapted to that of the hard material grains.
  • the particles received in the depressions are individually positioned in this way exactly, namely according to the arrangement or distribution of the depressions on the working surface of the tool.
  • the hard material grains can thus be applied with a defined distribution density by the receiving depressions are distributed appropriately distributed on the working surface of the tool.
  • a distribution density which is particularly advantageous in practice results from an arrangement of the depressions from which, in the case of the finished tool, a certain spacing of the hard material grains relative to their inner sides takes place in relation to the particle size.
  • the recesses according to the invention are generally dimensioned and designed such that they can each accommodate one hard material grain. However, it is within the scope of the invention also possible to dimension and shape the depressions depending on the particle size and / or shape of the particles so that they can each accommodate more than a single grain.
  • the depressions are introduced into the basic body by drilling in or impressing the same. Since the main body is usually metallic, both manufacturing methods can be applied without great expenditure on equipment. Depending on the nature of the body, however, other manufacturing methods, such as laser-operated methods, are applicable in principle.
  • the invention further provides that the recesses introduced into the base body are filled with a preferably electrically conductive adhesive, wherein the excess adhesive is drawn off via the base body and then the hard material grains are thrown onto the base body. In this way it is ensured that only the particles located in the depressions remain stuck on the working surface of the tool.
  • the invention also provides that the resulting particle coating is then galvanically nickel-plated, wherein the nickel layer is deposited on the adhesive and the hard material grains are enclosed by the nickel bond. They thus remain completely enclosed in the depressions up to a certain grain height, whereby physical and / or chemical bonds, such as, for example, a nickel or solder bond, also support the retention of the particles in the desired direction. It is advantageous in this sense if the depressions in the base body are designed and dimensioned in such a way that a certain orientation of the hard material grains, which are preferably in the form of dodecahedra, is thereby effected.
  • the wells are sized and configured so that they can accommodate hard grains of uniform grain shape and / or grain size.
  • the dressing tool shown serves for dressing the flanks of grinding worms, which are used, for example, for grinding appropriately designed gears.
  • Such dressing tools can have one or more such basic body 2 with a corresponding number of working surfaces 6. These work surfaces can also be provided with special profile shapes and also the dressing tools can be made as a dressing gears.
  • the dressing tool 1 consists of a base body 2 with a cylindrical shaft 3, which is coupled with a rotary drive for driving the rotatable about the axis 4 base body 2.
  • the flanks 5 of the main body form the working surfaces 6 of the tool. For this purpose, they are equipped with a coating of hard material grains 7.
  • the embedded by a nickel bond 9 hard material grains 7 are provided as diamond grains having a grain diameter of, for example, 400 microns and a preferably dodecahedral shape.
  • a nickel bond 9 hard material grains 7 are provided as diamond grains having a grain diameter of, for example, 400 microns and a preferably dodecahedral shape.
  • other grain shapes and sizes as well as other materials such as superabrasive or similar superabrasive materials may be used.
  • FIG. 3 to FIG. 5 are in the body 2 according to the invention exactly defined distributed arranged recesses. 8 introduced, the shape and dimensions of which is adapted to the hard material grains 7 so that they can absorb the grains up to a certain grain height approximately form-fitting. Due to their particular configuration, they are also able to give the hard material grains 7 the orientation that is optimal for the function of the tool. Thus, the depth T of the respective depression and also the projecting height H of the grain can be determined, and thus the parameters for an optimum dressing and a maximum service life of the tool can be designed accordingly.
  • the recesses 8 are preferably either drilled, impressed and / or lasered into the main body 2, depending on which material of the normally metal base body 2 is made.
  • the distribution density of the recesses 8 on the working surface 6 of the tool is chosen so that in the finished tool, the distances between the grains 7 on the inside, for example, about half the grain size D amount, these distances are uniform in the described embodiment, both in the horizontal and in the vertical direction ,
  • the recesses 8 with respect to the central axis 4 of the tool outside distributed denser than inside mounted so that the finished tool this outside with more hard grains per unit area is provided as the inside, as normally the outside grains and thus longer in use than the internal particles.
  • the recesses 8 on the work surfaces 6 of the body After introducing the recesses 8 on the work surfaces 6 of the body they are filled with an electrically conductive adhesive, and the excess adhesive is then removed, for example, with a doctor over the base body 2. Thereafter, the diamond grains 7 are thrown onto the work surface 6, wherein the grains remain adhesive only in the recesses 8 filled with adhesive.
  • the grain distribution can be varied over the work surface 6 in a variety of ways. In this way always results in a well-defined distribution of the grains on the working surface of the tool.
  • the inventive design of the tool thus has the advantage in principle that it ensures a precise positioning of the hard grains on the working surface of the tool which can be precisely determined in advance. By appropriate definition of this size, the tool can be improved so that it is optimal for the particular application.
  • the resulting diamond coating can then be galvanically nickel-plated.
  • the adhesive for the diamond grains is selected to be compatible with the chemicals of the subsequent galvanic process. Since the adhesive used is electrically conductive, the nickel layer can be easily deposited on it so that the diamond grains glued into the recesses are neatly enclosed by the nickel bond. In this way the indentation edges become sealed, and the diamond grains get a better backing.
  • the embodiment described above relates to a base body for dressing tools, which are intended in particular for dressing grinding worms.
  • the invention is also readily applicable to other similarly working tools, such as grinding or honing tools.
