Definitions

  • the present invention relates to an abrasive coating for grinding tools, in particular grinding wheels.
  • grinding tools are customary which have so-called hot-pressed or pressure-free sintered hard abrasives with synthetic resin or metal or ceramic or the like Diamond or CBN (cubic crystalline boron nitride), which are effective as a hard, abrasion-resistant abrasive grain.
  • Such grinding tools result in only very small chip spaces, so that the grinding wheel clogs quickly and has to be re-profiled or dressed; apart from the other signs of wear and tear, in particular due to the unfavorable grinding temperature distribution in the synthetic resin or ceramic abrasive coating.
  • abrasive coating according to the invention permits a segment-free, that is to say continuous and thin coating on a grinding wheel body, which leads to simpler production and permits a higher load capacity of the wheel. Since the covering is also comparatively specifically lighter and more homogeneous, such a grinding wheel tends to be less unbalanced and has a vibration-damping effect.
  • the high mechanical strength and the good bond with the metallic support create the best conditions for use in the field of high-speed grinding.
  • abrasive coating which is essential to the invention, can also be seen if the diamond or CBN grain size MD20 (20 microns) to D301 (50/60 mesh) or MB20 (20 microns) to B 427 (40/50 mesh).
  • the grinding lug size resulting from the granulation of the metal or ceramic bonded, hot-pressed or pressure-free sintered abrasive with diamond or CBN grain should be 1/4 to 3 mm. It is advantageous if the diamond or. CBN concentration in the grinding tunnel does not exceed 8.8 carats per cubic centimeter (FEPA K200 or 480V). Furthermore, the volume fraction of the grinding lugs in the grinding surface should be approx. 30 to 60%.
  • the present invention relates to a method for producing the abrasive coating according to the invention for abrasive tools, in particular grinding wheels.
  • this method is distinguished by the fact that grinding lugs are formed from a hot-pressed or pressure-free sintered, metallic or ceramic-bonded grinding granulate with diamond or CBN grain, and this bound with a synthetic resin binder and applied to a carrier.
  • Hiebei can use grinding pellets in the form of micropellets from 0.2 to 3mm or grinding pellets obtained by granulating existing or recyclable hot-pressed or pressure-free sintered, metallic or ceramic-bonded grinding pads with diamond or CBN grit.
  • the present invention relates to a grinding wheel, produced by the method according to the invention.
  • the known grinding pad 10 shown in FIG. 1 comprises an abrasive with diamond or CBN grain 11, which is embedded in a synthetic resin or metallic or ceramic bond matrix 12 and is connected to the abrasive coating 10 by hot pressing or pressure-free sintering.
  • Grain and binder can be present as desired in the abrasive coating 10 and can also contain additives such as support grain, fillers, lubricants and plasticizers.
  • such an abrasive coating in granular form is now used as a grinding stud 13 for a completely new abrasive coating 14 (FIG. 2), these grinding studs 13 being bound by means of synthetic resin binders 15 and being applied to a carrier (grinding wheel or the like; not shown in more detail) .
  • Hiebei can, as already mentioned, a grinding granulate in the form of micropellets of 0.2 to 3 mm or a granulation of existing or recyclable hot-pressed or pressure-free sintered, metallic or ceramic-bonded grinding surfaces of the aforementioned type with diamond or CBN for the grinding lugs 13 Grain-derived grinding granules can be used.
  • a comparison of the abrasive coatings from FIGS. 1 and 2 shows that in the inventive abrasive coating according to FIG. 2, significantly larger chip spaces 162 are formed compared to the chip spaces 161 in FIG. 1.
  • FIG. 2 shows that a better course of the grinding temperature can be achieved by incorporating grinding studs 13 formed from the starting granulate by distributing them within the grinding studs and thereby protecting the binding matrix 15.
