Definitions

  • the invention relates to a diamond form dressing roller for dressing grinding wheels with a ceramic, Bakelite or metallic bond, which carries a coating of diamonds on a surface of a base body, which is limited to the outside by the large diameter of the roller.
  • Grinding disks with geometrically defined profiles on their grinding surface are used to grind profiles into workpiece surfaces. These profiles must first be worked into the new wheel by dressing and then reworked from time to time due to grinding wheel wear.
  • a profile grinding wheel is dressed either with a profile dressing roller bearing the workpiece contour on its surrounding surface or with a diamond form roller.
  • a form roller is also laterally guided by suitable controls during dressing so that the required grinding wheel profile stored in the control is created.
  • the smallest concave radius to be dressed on the grinding wheel corresponds to the convex radius R on the diamond roller.
  • Radii with R % 0.2 mm are often required.
  • Suitable form rollers can either only be made with small grain diamonds or the radius R must be created 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 have been developed, the circumferential surface of which is cylindrical.
  • the diamonds lie in a layer next to one another on the cylindrical circumferential surface parallel to the axis of rotation of the tool.
  • Known (DE-A 1 093 692) is a dressing tool with a diamond layer which is aligned radially to the axis of the grinding wheel. It is a fixed honing tool for dressing, which is not suitable for form dressing in the precision process, because with continuous wear the effective surface area of the diamond grit increases, so that the operating conditions change depending on wear.
  • the object of the invention is therefore to make diamond shaped rollers usable for small radii over a longer service life than was previously economically possible.
  • a form dressing roller according to the preamble of claim 1 which is provided only with a single coating of diamonds of narrow size, which is single-layered in the direction of the axis of rotation and multi-layered perpendicular to the axis of rotation.
  • Such a form roller allows the processing of profiles with very small radii without the effective width being reduced when worn changes.
  • a long service life can be used for this, because after the outer diamonds wear out, the diamonds underneath are to be used continuously until the diamond layers are completely used up under the same conditions.
  • 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 multilayer diamond coating 4 with the thickness D 1 with the diamonds 5 located on the outermost circumference generate, be closely classified by sieving.
  • a sieve fraction can be used which has passed a sieve with a mesh size of 330 ⁇ m, but remains on a sieve with a mesh size of 290 4 m.
  • the sieve fraction can be grain-size classified in a known manner and only the predominantly round or blocky grains can be used.
  • the steel base bodies 1 and 2 are simultaneously ground down by contact with the grinding wheel, so that the diamonds available on the outer circumference always protrude beyond the base body because the diamonds wear less because of their hardness as 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 because of the successively engaging, diamond-tipped circumferences up to the dash-dotted line 8, but with the pointed shape of the diamond form roller remains, the lifespan of this dressing tool is far longer than the lifespan of known diamond form rollers, in which the wear after usually only half a diamond coating layer brings about the end of the lifespan due to an impermissibly large form deviation.
  • 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.
