Definitions

  • the invention relates to the use of a grinding or the like tool made of a ceramic material and a method for producing grinding or the like tools coated with extremely hard abrasive grains.
  • grinding and “grinding tool” used here and below are to be understood in the broadest sense, i.e. that in particular also “honing”, “hard cockroaches”, “scraping”, “honing” and “dressing” including the tools used for this are to be understood.
  • extreme hard abrasive grains which should be understood to mean diamond, CBN, tungsten carbide and the like grains as used in abrasive, i.e. no uniformly directed cutting edges of tools of the type mentioned are known.
  • the invention has for its object ways and means to find, with which tools of the type mentioned are cheaper to grind than before, in particular the grinding tool used for this should be simple and cheap to manufacture.
  • the solution should also be applicable to other grinding and similar tools that are used in fine gear machining.
  • the problem is solved primarily in the use of a known ceramic grinding tool as the base body for a grinding tool coated with extremely hard abrasive grains.
  • a plate-shaped grinding wheel 1 made of ceramic material is covered with extremely hard abrasive grains 3 at least on one end face 2 thereof.
  • the end face 2 to be covered is coated with an adhesive 4 and the abrasive grains 3 are applied immediately thereafter. This can be done by sprinkling or by applying with a brush.
  • the abrasive grains 3 are pressed against the grinding wheel. The abrasive grains 3 slide into the pores 5 of the ceramic material 6 (FIG. 2), into which the adhesive 4 has already “sucked in”.
  • the grinding grains 3 can be pressed in with a correspondingly shaped pressing tool, not shown, but also by brushing in with a simple tool, for example a spatula, in an extreme case even with the finger.
  • Dan adhesive 4 is then allowed to harden according to the manufacturer's instructions. In the case of an adhesive based on epoxy resin, this can be, for example, 2 hours at about 150 ° C.
  • the grinding wheel according to Fig. 1 is briefly pulled off in the area of its outer contour, e.g. with a single-grain diamond dresser. Each time you pull off, new abrasive grains are exposed on the occupied end face 2, which then act as "cutting".
  • a grinding wheel 1 coated with diamond grains as described above can be used both for grinding gear-like tools coated with CBN grains in accordance with DE-OS 33 36 593 and for grinding hardened workpiece gear wheels in particular.
  • a grinding wheel coated with CBN grains is usually used to grind hardened workpiece gears.
  • a gear-shaped tool 7 (FIG. 3) can be coated in the same way on its tooth flanks with extremely hard abrasive grains. To do this, it only needs to be precisely aligned and ground beforehand. To press in the abrasive grains 3, the tool 7 is unrolled with a master wheel 8, since the abrasive grains 3 then only protrude very little and evenly from the previously ground tooth flanks.
  • a grinding wheel 10 with a circular cross-section (cylindrical, conical, spherical, etc.), which is effective on its peripheral surface 12, as shown in FIG. 4, can be coated with extremely hard abrasive grains in basically the same way. To do this, it is precisely aligned and subtracted beforehand. To press in the abrasive grains 3, the grinding wheel 10 is allowed to roll on a correspondingly shaped counter surface or such a counter surface is guided along the rolling grinding wheel. If the grinding wheel 10 is also to be covered on one or both end faces 11, the same procedure can be followed as described above in connection with the plate-shaped grinding wheel 1.
