Definitions

  • the invention relates to a dressing tool for machining abrasive bodies by means of a rotating dressing roller or a linearly moving dressing block and a plurality of projections arranged one after the other in the cutting direction on the circumference of the dressing roller or on an edge of the dressing block, the cutting plates preferably made of polycrystalline synthetic diamond, wear cubic crystalline boron nitride, hard metal or ceramic, which partly overlap to form the profile of the dressing tool, as is known for example from DE-A-2 238 387.
  • the cutting plates have the same shape and are arranged as perfectly as possible on the tool. This is to ensure that each individual cutting edge of the cutting plates from the workpiece to be machined only removes a relatively small, precisely predictable chip size.
  • only dressing tools with a relatively simply shaped geometric dressing profile can be produced in this way.
  • Dressing tools for complicated profiles are in the VDI magazine volume 120, No. 24, December 1978, by H.-R. Meyer under the title «Diamond and CBN tools for machining tasks in mechanical engineering on pages 85 to 95. Accordingly, diamond dressing rolls with complicated profiles can only be produced in a galvanically bound version with a stochastically distributed surface finish, but this means that the advantages which can be achieved with generic dressing tools as a result of the definable arrangement of cutting plates are eliminated.
  • the object of the invention is to develop the generic dressing tool in such a way that it can have a complicated dressing profile.
  • the object is achieved according to the invention in that the cutting plates have at least two different successive projections in the cutting direction.
  • the cutting plates can be obtained in a particularly simple manner by means of coating a base body having the desired profile, but it is also possible to use commercially available polycrystalline synthetic diamond plates. These are obtained, for example, in the form of circular disks 1.5 or 3.2 mm thick and 13.7 mm in diameter and can then be used by means of spark erosion or by means of an electron or laser beam or a hot oxygen beam or by grinding or shaping, for example by pressing to be edited. In this way, the excellent cutting properties of such cutting inserts can be used. Reworking is possible without difficulty since the profiled cutting plates can be re-profiled and, if necessary, replaced.
  • FIG. 1 shows a dressing roller 10 according to the invention, which consists of a base or shaft body 12 which has eight segments 14 in the exemplary embodiment.
  • Tungsten carbide plates 16 are arranged on the chest surfaces of the segments 14.
  • a carrier material 20, which serves to hold profiled cutting plates 18 polycrystalline synthetic diamonds, is fastened to these in the head region.
  • the carrier material 20 is preferably in the form of a hard metal base.
  • a cutting material other than polycrystalline synthetic diamond can be used and can also be arranged directly on the chest surfaces.
  • the diamond plates 18 can be produced by means of spark erosion or by means of an electron or laser beam or a hot oxygen jet and correspondingly high-pressure water or by grinding or shaping z. B. processed by pressing. This ensures a high precision of the profiles of the diamond cutting plates 18, so that when the dressing tool 10 is used, a grinding wheel work surface is made available which is not only characterized by geometrical accuracy, but also by an extremely high sharpness which leads to a leads to longer service life.
  • a chip chamber 26 is provided in front of the teeth 14, into which the corresponding parts can be accommodated. Complex removal of the corresponding particles is not necessary, as is the case when using known dressing tools with continuous dressing rollers provided with surfaces with diamond grains.
  • FIG. 3 shows a side view of a dressing block 30 which has projections 32, on the breast surfaces of which cutting plates 34 are arranged.
  • the cutting plates 34 are hard or superhard materials which consist of a compact unit in the form of finished profiled plates or of base bodies coated with the cutting materials.
  • the projections 32 can be an integral part of the base body 28 or can be fastened thereon.
  • profiled cutting inserts made of polycrystalline synthetic diamond are used, which in turn are connected to the base body 28 by means of a carrier material (which at the same time forms the projections).
  • a carrier material which at the same time forms the projections.
  • chip chambers 36 in front of the projections in the dressing block 28.
  • FIG. 4 shows a front view of the dressing block 30 according to the invention and clarifies that the profile surface of a projection is composed of a plurality of machined cutting plates made of hard or hard material.
