Definitions

  • the invention relates to a method for dressing grinding wheels with diamond or cubic crystalline boron nitride using a driven dressing roller and an additional dressing aid.
  • Profiled diamond grinding wheels are pre-profiled during their production by a pressing process and then ground with ceramic wheels, such as silicon carbide grinding wheels.
  • ceramic wheels such as silicon carbide grinding wheels.
  • This is a complex process and post-profiling must be carried out by the manufacturer. It has therefore already been started to apply only one grain layer for the use of profiled grinding wheels with diamond or cubic crystalline boron nitride in a galvanic bond, but then such wheels cannot be reused after the loss of shape accuracy.
  • the dressing is used for dressing and profiling corundum or silicon carbide disks with a ceramic bond positionedo known profile rolls made of steel or hard metal. Such a profiled roller presses the abrasive grains most protruding from the bond with each revolution of the grinding wheel. These abrasive grains partially break out of the brittle bond of the grinding wheel under the applied pressure, but partially block the grinding surfaces of the grinding wheel by being pressed in. Also known are profile rolls made of silicon carbide in ceramic or Bakelite bond for dressing grinding wheels, (US-PS 24 56 762) but only for grinding wheels with diamonds in ceramic or Bakelite bond.
  • Diamond tools are regularly used for dressing grinding wheels with corundum or silicon carbide, such as diamond dressing rollers, which, due to their much greater hardness, enable the shaping of such grinding wheels.
  • the dressing stone therefore has the task of cleaning the grinding wheel surface from crushed bond and broken grain particles.
  • a grinding wheel is to be provided with a thread profile, the teeth of which have only very small tip radii, i.e. whose teeth are pointed in cross section, the subsequent use of the fixed dressing aid will round off the tooth tips, which is undesirable or not This is due to the fact that when a fixed dressing aid is subsequently used, it is not possible due to the high relative speed between the dressing aid and the grinding wheel to obtain a sufficient grain protrusion of the cubic crystalline boron nitride bodies beyond the bond level, for example if the peripheral speed of the grinding wheel 30 m / sec. is.
  • the object of the invention is to improve the effectiveness of known dressing aids in order to create the possibility of also profiling diamond grinding wheels with diamond dressing rollers, and also during the grinding of a workpiece, diamond grinding wheels instead of such grinding wheels with cubic crystalline boron nitride being understood here as well .
  • the dressing of the grinding wheel is carried out using a driven dressing roller diamond and an additional driven dressing wheel, which with a relative speed of 0.5 to 6 m / sec. rotates to the peripheral speed of the diamond grinding wheel.
  • the diamond dressing roller can have a different peripheral speed than the grinding wheel, it being assumed that it is generally expedient to rotate the diamond dressing roller in the opposite direction to pre-profile a grinding wheel, so that, for example, the grinding wheel and also the diamond dressing roll rotate counterclockwise, while in finished profiling both discs work in the so-called synchronism, one rotating clockwise and the other counter-clockwise in order to achieve a certain grain protrusion over the bond. This grain protrusion is then increased to the desired level by the second dressing disk operating at a low relative speed.
  • the new method also has the advantage of being able to continuously carry out re-profiling to the necessary extent while grinding a workpiece.
  • the driven disk used as an additional dressing aid can consist of ceramic or Bakelite-bonded silicon carbide, with silicon carbide also replacing it Corundum can occur.
  • the use of such a material has the advantage that the dressing wheel continuously adapts precisely to the profile of the grinding wheel, which is continuously produced by the diamond dressing roller, so that the dressing wheel does not enter the profile of the grinding wheel and subsequently, for example, removes the tips of tooth profiles .
  • the grinding wheel 1 shown in the drawing with a coating 2 with diamond or cubic crystalline boron nitride rotates clockwise according to arrow 3.
  • a diamond dressing roller 4 is provided, which rotates counterclockwise in accordance with the arrow 5, a relative speed between the diamond dressing roller 4 and the grinding wheel 1 should be maintained.
  • the diamond roller 4 is delivered in accordance with the arrow 6.
  • a disk 7 is provided which rotates counterclockwise according to arrow 8.
  • This dressing wheel 7 consists of ceramic or Bakelitic bonded silicon carbide or corundum and is delivered according to the arrow 9.
  • the dressing wheel 7 is driven such that it has a peripheral speed of 29 m / sec. has when the peripheral speed of the grinding wheel 1 30 m / sec. is, so that the relative speed between the two discs 1 m / sec. is.
  • This low relative speed makes it possible to work out the individual grains beyond the bond when dressing the grinding wheel 1 at high circumferential speed by means of the diamond dressing roller 4, while at the same time a workpiece 10 can also be ground using the grinding wheel 1 the arrow 11 is delivered.
