Definitions

  • the invention relates to a method for conditioning abrasive tools according to the preamble of patent claim 1.
  • Grinding tools are known to have a rotationally symmetric or a prismatic geometry.
  • a continuous or interrupted abrasive coating is applied in one or more layers, wherein the abrasive grains of the abrasive coating are bonded by a ceramic, organic or metallic bond.
  • Such grinding tools are known to be used for cutting by means of geometrically indefinite cutting edge.
  • conditioning is required from time to time during operation.
  • Profiling and sharpening is usually summarized under the term dressing.
  • the original profile which has been lost due to wear, must be restored from time to time. Therefore, with the dressing tool, the original profile must be readjusted by a corresponding movement path relative to the grinding tool or by the profile of the dressing tool itself. This can be done simultaneously sharpening of the abrasive coating. In unprofiled grinding tools also takes place from time to time sharpening.
  • bond and / or abrasive grains are partially or completely smashed, it depends on the type of bond with the Schleifkömung from, in which way bond and abrasive grains behave during dressing.
  • abrasive grains are splintered or smashed, while in the case of a softer bond, they are themselves removed to such an extent that the abrasive grains can again engage with the workpiece.
  • the dressing of grinding wheels with corundum or silicon carbide is usually carried out with the aid of a diamond tool.
  • Diamond and Bohrnitridin are mostly trained with silicon carbide Abrichtschleiffractionn.
  • Diamond dressers are also used to dress drilled nitride grinding wheels in synthetic resin or Spurtmetallitatien. For profiling of diamond and Bohrnitridschleiffractionn is also known to make a crushing with profiled steel rollers.
  • the binding consists of a chrushierbaren metal binding, which can be profiled by rolling.
  • the dressing tool is gradually delivered axially parallel to the diamond and Bohrnitridschleiffraction.
  • Bonitride grinding wheels are also dressed with a diamond dressing profile roller.
  • so-called diamond dressing form rollers have become known. While a dressing profile roll the negative profile to the profile of Having a grinding wheel, has a Diamantabrichtformrolle usually a cut-angle angular abrasive coating, wherein the Formabrichtrolle the profile of the grinding wheel nachology.
  • the invention has for its object to provide a method and apparatus for conditioning grinding tools with rotationally symmetric or prismatic geometry, which can be carried out particularly effectively and easily.
  • the sonotrode of an ultrasonic vibrator is equipped with a tool section which consists of very hard material or has a very hard coating.
  • the vibratory tool section is set into a high-frequency vibration via the sonotrode, whereby the bond and / or the abrasive grains of the abrasive coating are partly or completely shattered when contact between the abrasive coating and the dressing tool is made.
  • the dressing tool is held stationary while the grinding tool is moved relative to the dressing tool section.
  • the workpiece in this case the grinding tool, can be moved as desired in space and can therefore be moved along a predetermined path relative to the dressing tool section in order to carry out a corresponding conditioning operation.
  • This consists primarily in a profiling and / or sharpening of the abrasive coating (dressing). Alternatively, a cleaning can be done.
  • the mechanical vibration of the dressing tool section is 20 kHz to 1000 MHz.
  • the amplitude may be between 10 nm and 1 mm according to a further embodiment of the invention.
  • the dressing tool section comprises hard metal, ceramic, polycrystalline diamond or the like. It is understood that the dressing tool portion may be mounted on a support, such as by gluing, soldering or the like.
  • the carrier in turn is suitably attached to the sonotrode of the ultrasonic vibrator.
  • the dressing tool portion may have a profile, such as a profile dressing roller.
  • the dressing tool portion acts like a high frequency operated hammer which oscillates on the coating of the grinding tool to achieve the desired fragmentation or disintegration of the abrasive grains.
  • the dressing process can be selectively controlled in a desired manner as a function of the binding selected for the abrasive grains.
  • a grinding wheel 10 is shown in section, in which on a cylindrical support 12, an abrasive coating 14 is applied from abrasive grains.
  • the abrasive coating is semicircular in cross section. Thus, there is a profile grinding wheel.
  • a not further illustrated dressing tool 16 has at its free end a coating of hard material 18.
  • the tool 16 is excited by means of an ultrasonic vibrator 20.
  • the vibrator 20 is moved along the double arrow 22 and the double arrow 24, respectively, to travel along the profile of the abrasive pad 14.
  • the ultrasonic vibrator 20 may be stationary while the grinding wheel 10 is moved accordingly. At the same time, it performs a rotary movement. Grinding wheel 10 and ultrasonic vibrator 20 can be arranged with a suitable machine to perform the described movements.
  • the ultrasonic vibrator 20 holds a dressing tool 16a with a circular-shaped dressing surface or edge 18a whose profile is complementary to the desired profile of the abrasive coating 14.
  • the tool 16 a is applied against the profile of the abrasive pad 14, wherein the grinding wheel 10 is rotated.
