Definitions

  • the invention relates to a diamond form dressing roller for dressing grinding wheels with a ceramic, Bakelitic or metallic bond.
  • Grinding disks with geometrically defined profiles on their grinding surface are used to grind profiles into workpiece surfaces. These profiles must first be brought into the new wheel by dressing and also regenerated from time to time due to the wear of the grinding wheel.
  • form grinding a grinding wheel with a pointed profile is used, for example a tip radius of 0.5 mm and an included flank angle of 60 ° with the help of a suitable, usually multi-axis control so guided on the workpiece surface that the profile specified by the control is generated on the workpiece surface.
  • the control can consist of a postform control or a numerical control.
  • the grinding wheel When grinding profiles, the grinding wheel carries the complete, negatively compliant workpiece profile on its surrounding surface. This means that profile controls and at least one feed movement can be omitted. This process is used for series and mass production due to the saving of grinding time.
  • the grinding wheel is dressed either by diamond dressing rollers, which carry the workpiece profile on their surrounding surface, or by diamond shaped rollers. Similar to form grinding, the latter are guided by suitable controls during dressing in such a way that the required grinding wheel profile stored in the control system is created.
  • the minimum required tolerances of the workpiece profiles are up to 2 pm today.
  • the kinematics of the control must have a corresponding accuracy, but also the area around the diamond form roller itself.
  • the profile of the diamond form roller is taken into account when creating the data carrier for the grinding wheel profile. Depending on the profile train currently being trained, different profile zones of the diamond form roller come into engagement. The profile of the diamond form roller must therefore be manufactured with low shape tolerances.
  • the smallest dressable concave radius on the grinding wheel is the same as the convex radius R on the diamond form dressing roller. Radii with R ⁇ 0.2 mm are often required. Such form rollers can either only be produced with a small diamond grain size or the radius R must be achieved on the form roller by grinding with diamond grinding wheels. With small radius sizes, however, the wear of the diamond form roller is correspondingly higher, so that the use of such dressing tools proves to be uneconomical.
  • diamond form rollers which, for example, have a cylinder part on their surrounding surface.
  • the cylinder part is delimited on both sides by radii, which in turn merge tangentially into an end surface inclined at, for example, m 30 °.
  • a plurality of diamonds are arranged on the peripheral surface parallel to the axis of rotation of the tool in a layer lying next to one another. Larger grain sizes can be used for these at the same radius R because of their geometric shape than in the previously described embodiment. Because of the additional straight dressing zones, more diamonds are used. This extends the lifespan.
  • rollers are further restricted by their geometrical shape, because only concave radii with an included angle of ⁇ 90 ° or ⁇ 90 ° + ⁇ can be dressed.
  • diamond shaped rollers are still associated with an inadequate service life due to the wear occurring on the radius, because the most frequent contact and during profile dressing in the region of the radius R. and thus the greatest burden occurs. All these known form rollers have the disadvantage that their service life is at the latest when a layer of diamonds is worn out.
  • the invention has for its object to provide diamond form rollers with a longer life and make diamond form rollers usable even with smaller radii than previously seemed economically possible.
  • a diamond form dressing roller for this purpose, which is characterized in that the form roller on a surface that after is limited on the outside by a large diameter of the tool, is coated with a diamond coating which is single-layered in the direction of the axis of rotation and multi-layered perpendicular to the axis of rotation.
  • a diamond coating which is single-layered in the direction of the axis of rotation and multi-layered perpendicular to the axis of rotation.
  • the use of diamonds that are narrowly classified in terms of their grain size comes into consideration. The lower the permissible radius tolerance, the lower the permissible grain size tolerance of the individual diamonds to one another.
  • a second base part can support the diamond layer from the side opposite the first base part. An embodiment of such a diamond form roller is shown in a drawing and explained below.
  • the base parts 1 and 2 with the diameter D are preferably made of steel. Between the base body parts 1 and 2 is the single layer in the direction of the axis of rotation 3 and perpendicular to the axis of rotation 3 multi-layer diamond coating 4 with the thickness D 1 with the diamonds 5 located on the outermost circumference.
  • the diamonds can be around a defined radius R with a close tolerance generate, be closely classified by sieving.
  • a sieve fraction can be used that has passed through a sieve with a mesh size of 330 ⁇ m, but remains on a sieve with a mesh size of 290 ⁇ m.
  • the sieve fraction can be classified in a known manner, and only the predominantly round or blocky grains can be used.
  • the steel are ground round bodies 1 and 2 at the same time through contact with the grinding wheel, so that the particular property to the outermost periphery available diamonds always protrude beyond the basic body, because the diamond because of their hardness g wear less than the steel base bodies 1 and 2 and the bond 6 arranged between the diamonds.
  • a state of wear 7 is shown in dashed lines as an example. Due to the successively engaging, diamond-tipped circles up to the dash-dotted line 8, but the pointed shape of the diamond form roller is retained, the life of this dressing tool is far longer than the life of known diamond form rollers, in which the wear is mostly only half a diamond layer already Caused by an inadmissibly large shape deviation at the end of the service life.
  • the diamonds are advantageously bound to the base part 1 by means of an electrodeposited nickel coating, the thickness of which is smaller than the diamond grain size.
  • other types of binding such as bronze, steel, synthetic resin and the like can also be used.
  • a double bond can preferably also be carried out, the single-layer diamond coating being bonded to one base part by galvanic precipitation, but the other base part is sintered, for example, with a bronze, which can optionally be filled with wear-reducing fillers such as cobalt.
  • a further embodiment consists in that the base body part 2 is made of sintered bronze, the sintered bronze being sintered directly onto the base body part 1 equipped with the diamond coating.
