Definitions

  • the invention relates to a method for producing a dressing tool for a grinding tool, preferably for a grinding worm, wherein the dressing tool has at least one, preferably annular, radially extending projection.
  • a dressable multi-start grinding worm is generally used.
  • the dressing of the grinding worm is again done with a single or multi-grooved dressing roller.
  • the present invention relates to a method for producing such a dressing tool. Preference is given to multi-section solid profile rollers, which can be used for the efficient dressing of grinding worms.
  • a mold ring is produced by another method, with the workpiece-specific Profile is provided.
  • a diamond or nickel layer is deposited on this profile in a galvanic process, which - after being glued to a core - ultimately results in the abovementioned dressing tool after various further process steps.
  • the manufacturing process is very complex. Often, for the production of the diamond or nickel layer of the mold ring is up to three weeks in a galvanic bath.
  • the profile of the dressing tool thus produced sometimes has errors that can be attributed to various causes.
  • the outer flanks of the profile "fold" outward, which is attributed to stresses in the structure.
  • thermal stresses are noticeable, which lead to errors in the profile.
  • the invention is therefore the object of a generic method in such a way that the profile of the dressing tool produced as well as the ideal contour corresponds; thus profile defects are to be eliminated on the dressing tool.
  • it should be ensured that the deformation of the nickel layer remains as low as possible. Accordingly, the dressing tool should have a precise geometry.
  • an open grid structure with openings is preferably used as the support element, so that the radially inner surface is not radially closed by the support element. Rather, therefore, the replacement of the electrolyte required for the production of the coating by the support element is not or hardly hindered.
  • the support element preferably extends over a width which corresponds to between 90% and 100% of the width of the dressing tool.
  • a structure which has a number of rings which extend in the circumferential direction of the radially inner surface, wherein the rings are interconnected by means of transverse struts, wherein the transverse struts extend in the axial direction of the dressing tool.
  • the rings and / or the transverse struts are preferably made of metal.
  • the rings and / or the transverse struts preferably have a circular cross-section. In this respect, a wire with a circular cross-section can be used as a base material for the production of the support element.
  • the number of rings preferably results from the number of projections plus one. In this case, therefore, there is a ring on both sides of each recess of the mold ring.
  • the rings and the cross struts can be materially connected to each other before their use or prior to introduction into the mold ring; this is in particular intended for welding or soldering.
  • the mold ring can at least temporarily rotate about its axis during the implementation of the above step c). It can thereby be ensured that the abrasive material (in particular the diamond powder) is retained by the centrifugal force in the recesses of the molding ring until it is fixed to the surface of the recess by the (in particular galvanic) coating process.
  • the abrasive material in particular the diamond powder
  • the removal of the molding ring according to the above step d) is preferably carried out by machining, in particular by twisting, the molding ring.
  • one aspect of the present invention is to incorporate a brace (i.e., the support member) into the forming nickel layer during the preferably electroplated coating process.
  • This brace counteracts possible deformation and prevents it.
  • a galvanic coating electrochemical deposition, "galvanic nickel”
  • a chemical coating can also be provided (“chemically nickel”).
  • various coating materials are possible, with nickel being preferred.
  • the material of the support element is chosen so that it can be easily introduced into the nickel layer and thereby deformed as little as possible. It is ensured that the deposited galvanic layer can not deform.
  • the support element is galvanically connected to the previously already applied (as part of a first fixation of the abrasive material in the mold ring) galvanic layer already containing the abrasive body.
  • the configuration of the support element is chosen so that it counteracts an optionally acting deformation stress.
  • the support element is designed or designed so that a uniform deposition of the galvanic layer can be achieved even after the introduction of the support element.
  • the support element may not form a shield by name; the replacement of the electrolyte must be ensured.
  • the support element may be introduced before or after the diamondizing (that is, before or after the introduction of the abrasive material on the surface of the above-mentioned recesses).
  • the support member In the proposed embodiment of the support member is ensured that the support element during galvanizing causes no change in the grain density (number of grains on the surface) and no grain imperfections.
  • the proposed invention is used in particular in solid profile rollers or in the galvanic negative coating.
  • a dressing tool 1 is shown in the form of a dressing roller.
  • the dressing tool 1 consists of a rotationally symmetrical component which has an axial direction a and a radial direction r. In the axial direction, the dressing tool 1 has a width B.
  • the dressing tool 1 has three ring-shaped, circumferentially extending projections 2, which extend in the radial direction r. These projections 2 are provided with abrasive material 6 in the form of diamond powder (corresponding grain size, depending on the grinding tool to be dressed), so that a grinding worm can be dressed with the dressing tool 1. This method is known as such and need not be explained here.
  • FIG. 2 The production of such a dressing tool 1 is in FIG. 2 illustrated.
  • Central element for the production is a mold ring 3, which has a substantially hollow cylindrical shape.
  • recesses 5 are incorporated (ie ground in with high accuracy), which are congruent (congruent) formed with the projections 2 (negative method).
  • the abrasive material 6 (diamond powder) is initially placed in the production of the dressing tool 1, so that the surface 8 of the recesses 5 is at least partially covered or occupied by this abrasive material 6.
  • FIG. 2 is a state to see, in which the galvanic coating process is already largely completed, ie the area of the recesses 5 has already filled with the material of the coating and beyond detected a radially inward reaching area.
  • a support element 9 was introduced into the mold ring 3, which was at least partially integrated by the galvanic coating process in the forming dressing tool 1.
  • FIG. 2 It can be seen that the support element 9 has been completely integrated into the coating material, ie surrounded by it. Thus, therefore, the support member is materially connected to the resulting dressing tool 1. However, it is also possible that after completion of the coating process, the support element 9 is not completely surrounded by the coating material.
  • the mold ring 3 is removed, which can be done by a machining operation.
  • the dressing tool 1 is available for its intended use.
  • the coming to use support elements 9 can be seen again in a perspective view.
  • the support element 9 has a width b which corresponds substantially to the width of the dressing tool 1 or is slightly smaller than said width B.
  • the support element 9 consists of several (in the embodiment: four) rings 11, which are connected by equidistantly distributed over the circumference arranged transverse struts 12 (in particular: soldered). Preferably, 20 to 80 transverse struts 12 are circumferentially.
  • openings 10 that allow it during the coating process electrolyte can pass through the support member 9 and thus is not or hardly hindered by the support member 9 of the electroplating process.
  • the support element 9 (or support grid) designed as a lattice-shaped structure of longitudinal and transverse struts, which is stretched in the mold ring.
  • the dimensions of the grid structure are adapted to the contour to be supported.
  • the support element is thereby positioned in the mold ring, that the total width of the grooves (recesses) is covered and the support element is completely embedded in the nickel layer.
  • the coating 7 can be carried out in a finally desired extent in a second workstation. Before this occurs, however, the support element 9 is introduced into the mold ring 3 and integrally bonded by the coating process.
