Definitions

  • the present invention relates to a method for filling the free ends of the bristles of metallic brush tools with abrasive particles, in which the tool is first covered, leaving the areas to be occupied by the abrasive particles, then immersed in the partially covered tool Galvanobad, in which abrasive particles are introduced, applying a layer of preferably hard metallic carrier material with partial embedding of at least a plurality of abrasive particles on the exposed areas of the tool by electrolytic or electroless galvanic metal deposition, and then removing the cover from the relevant areas of the Tool can be made.
  • the present invention also relates to a metallic brush tool produced by this method.
  • a method for filling the peripheral edge of a grinding wheel with abrasive particles of the type mentioned at the outset has become known from US Pat. No. 3,957,593.
  • the grinding wheel is covered on its two end faces with a plastic tape.
  • this plastic band must be cut according to the circular end faces of the grinding wheel, such a measure for covering the surfaces not to be occupied with abrasive particles is possible in the case of large flat areas on grinding wheels, but is practically excluded as a corresponding covering measure for brush tools.
  • the object of the present invention is to provide a method for filling the grinding areas of metallic brush tools with abrasive particles of the type mentioned at the beginning, which makes it possible to cover the brush tool in a simple and quick manner to such an extent that only the free ends of the bristles of the brush tool can be filled with abrasive particles.
  • a metallic brush tool produced by this method is to be created.
  • This object is achieved in a method for filling the free ends of the bristles of metallic brush tools with abrasive particles of the type mentioned at the outset in that at least the part of the brush tool provided with the bristles is filled with a non-conductive material in such a way that it is converted into a non-conductive material Material is immersed, which solidifies in a certain ambient temperature range and is liquid, preferably viscous at a higher temperature, and that the ends of the bristles to be coated with the abrasive particles are then exposed again.
  • a metallic brush tool in which the free ends of the metallic bristles are galvanically provided with caps, which consist of a hard metal as the carrier material and partially embedded abrasive particles, preferably diamond particles.
  • the removal of the cover after providing the bristle ends with the abrasive particles is very easy and fast and completely possible that the brush tool is heated to the temperature in question, so that the liquid covering material can drip out between the bristles or out of the brush.
  • a metallic brush tool 11 for deburring in which the metalli rule bristles 12 are attached in bundles and in a helical arrangement to the tool rotation axis 13, which consists of two twisted metal wires and which can be clamped at its one free end 16 in a corresponding drive machine.
  • each free end 18 of a bristle 12 is provided with a cap 19 which is approximately two to three times the thickness of the metallic bristle 12.
  • the cap 19 consists of nickel as the carrier material 21, in which diamond particles 22 are partially or completely embedded as abrasive particles such that they protrude from the carrier material 21 by about 1/2 to 1/3 of their size.
  • a multiplicity of abrasive particles 22 are also embedded within the carrier material 21 and only a part of the abrasive particles 22 protrude from the carrier material 21.
  • the fully embedded particles 22 only emerge and become effective when the cap 19 wears out during the processing in question.
  • the grain size of the abrasive particles or the diamond particles 22 can be selected differently, depending on the field of application and the material to be processed.
  • the carrier material which is nickel here
  • the carrier material which is nickel here
  • the carrier material can also be replaced by another hard metal, such as chromium, or else by a softer metal, such as copper, zinc or the like.
  • the abrasive particles 22, which are diamond particles here can also be replaced by other abrasives, such as cubic boron nitride, corundum, sapphire, ruby or the like.
  • the brush is then clamped on a lathe, for example, and ground on the outer circumference with a normal grinding brush, so that the free ends of the bristles 12 are exposed to a length of about 1 to 2 mm. These exposed ends or tips 18 of the bristles 12 are then galvanically covered with the caps 19.
  • the exposed ends 18 of the bristles 12 are placed in an etching bath in preparation for the galvanic application of the caps 19, so that the bristle ends 17 are etched and thus chemically cleaned.
  • the metallic brush tool 11 which is therefore largely covered and in which only the above-mentioned bristle ends 18 are exposed for about 1 to 2 mm, is now immersed in an electroplating bath and thus represents one electrode.
  • the electroplating bath can be operated electrolytically or without current will.
  • a carrier material 21, in the exemplary embodiment nickel is deposited from the other electrode onto the exposed ends 18 of the bristles 12 and applied galvanically.
  • the diamond particles 22 are brought to the bristle ends 18 and embedded in the carrier material simultaneously with the galvanic application of nickel 21 to the bristle ends 18.
  • the brush tool 11 according to FIGS. 1 and 2 which is to be filled with diamond particles 22 as abrasive particles, is placed on a, for example, channel-shaped support in the electroplating bath, in such a way that it is completely immersed.
  • the diamond powder is then brought as a pulpy substance onto the upper area of the brush of the tool 11.
  • the electroplating bath is then activated, so that nickel is deposited as the carrier material 21 at the ends 18 of the bristles 12 and the particles of the diamond powder are also embedded in the process.
  • the brush tool 11 is rotated, whereupon the other opposite area of the brush is coated with the diamond powder and the electroplating bath is then activated again, so that the diamond particles are also galvanically applied to a certain extent of the carrier material at the bristle ends 18 are embedded in the carrier material.
  • the diamond particles only adhere imperfectly to the bristle ends 18, since until now these have only been embedded on the carrier material 21 with a relatively small layer thickness.
  • the further embedding of the diamond particles takes place at home in a second electroplating bath, which can also be operated electrolytically or without current.
  • the diamond particles are now embedded in such a way that the inner abrasive particles are completely embedded in the carrier material 21, while the outer diamond particles are only embedded to such an extent that they are at most about 1/4 to 1/3 of their size from the carrier material 21 protrude. The time it takes for this embedding depends on the data of the electroplating bath.
  • the diamond particles are anchored within the carrier material 21 in such a way that they can be used as abrasives and have a very long service life.
  • a certain amount of wear and tear is absorbed by the fact that the cap 19 has a certain size and further diamond particles are arranged within the cap 19, which are then exposed during the wear process and come into effect.
  • a carrier material 21 in the form of a thin layer, that is to say nickel them, after they have been etched in a special electroplating bath.
  • the covering material in the form of the non-conductive wax or other material must be removed again.
  • the relevant part of the brush tool 11 is heated to the appropriate temperature, so that the liquid wax can then drip out of the brush 11 again.
  • the non-conductive covering material is removed again in a simple manner.
