Definitions

  • the invention relates to a multi-edged reciprocating or rotating dressing tool, in particular for dressing grinding wheels, with a multiplicity of geometrically distributed uniform cutting tools.
  • elements that consist of a polycrystalline diamond material or cubic crystalline boron nitride material.
  • Dressing tools are known in which individual natural diamonds are arranged in a uniform geometric distribution.
  • traces are different because the natural diamonds themselves are different in shape. Because the shape of the individual diamonds cannot be predicted and their engagement length changes over their lifespan, the traces in the grinding wheel can only be predicted statistically. In addition, the individual diamonds are often of different hardness, so that there is different wear between the individual natural diamonds. As a result, the less worn diamonds leave deeper marks in the grinding wheel than the more worn diamonds. The result of this is that the grinding wheel causes a different amount of material to be removed when a workpiece is subsequently machined and thus causes a ripple in the surface! surface of the workpiece.
  • the object of the invention is to provide a dressing tool in which the effective cutting length of the cutting elements is the same over the entire service life of the tool, but moreover the tool can be used with a long service life even at extremely low manufacturing costs.
  • the cutting elements held in a binding are rod-shaped and aligned perpendicular to the working surface in at least two rows offset from one another in such a way that their individual cutting cates together have a continuous projection when the wear occurs of the tool continuously form the same cutting edge.
  • the use of such rod-shaped cutting elements made of multicrystalline diamond material in a direction perpendicular to the working surface of the tool promises a particularly long service life.
  • the tool can be manufactured at a relatively low manufacturing cost by sintering the individual cutting elements, which are produced according to the known high-pressure, high-temperature synthesis, into a bond, which consists, for example, of metal such as bronze or steel or hard metal.
  • This bond encloses the cutting elements on all sides, apart from the engaging end face of the cutting elements. Due to the all-round enclosure, the heat is optimally dissipated from the active site, so that the wear caused by the heat is minimized and the service life is thus extended.
  • the service life of the tool can be increased further in that the individual rod-shaped rows of cutting elements are arranged offset in height from one another, so that when cutting elements of a preceding row layer are used, the cutting elements of a subsequent row layer are replaced, again such that the preselected total cutting length remains the same.
  • the dressing tool shown in Figures 1 and 2 for dressing a grinding wheel 8 has a base body 1, the cylindrical head made of steel comprises a plurality of cutting elements 2, which are held in a binding 3.
  • the cutting elements 2 are cuboid and have a square cross section. Their length is more than three times the length L1 of their cutting edge.
  • the individual cutting elements 2 consist of a multicrystalline diamond material, which is produced after the high-pressure, high-temperature synthesis using a catalyst and contains a diamond fraction of more than 80 percent by volume.
  • a binding 3 is made of a for holding the cutting elements From Figure 2, which shows the arrangement on an enlarged scale, it can be seen that the individual cutting elements 2 are arranged at a distance from one another in several rows running parallel to one another, namely in the first row 4 there are three cutting elements 2 at a distance from one another and in a row 5 lying behind it, four cutting elements 2 at a distance from one another and standing at a gap from the cutting elements of the first row 4. Assuming that all seven uniform cutting elements 2 have an equally effective cutting edge L 1 , the effective total cutting width is the sum of L 1 , that is 7 x L 1 and forms a straight continuous line when viewed in the cutting direction.
  • a subsequent cutting element with its cutting edge is already available for use o
  • individual cutting elements according to FIG. 4 can also be arranged directly behind one another in an axial alignment, the head region and the foot region preferably being chamfered, so that the use of a cutting edge of the width L 1 is continuously ensured even in the event of a partial cutout of the foot of a cutting element above.
  • the tool When dressing a grinding wheel 8 which has a relatively high peripheral speed, the tool is moved along the peripheral surface of the grinding wheel 8 in accordance with arrow 12, which indicates its direction of advance. Since the peripheral speed of the grinding wheel is considerably higher than the feed speed according to the arrow 12, those parts of the cutting elements 2 are used as cutting edges which are transverse to the cutting direction, that is to say parallel to the feed direction arrow 12.
  • the solution according to the invention can also be applied breaking tools to rotating A as Figures 5 and 6 show.
  • a dressing roller 6 is provided for dressing a grinding wheel 8 with a profiled peripheral surface.
  • the individual rod-shaped cutting elements 2 are radially aligned with the circumferential surface of the dressing tool, again in a row in several rows, set to a gap.
  • FIG. 6 Such is also illustrated in FIG. 6 with a representation of three successive rows of rod-shaped cutting elements placed on a gap on a dressing roller with a cylindrical peripheral surface.
  • rod-shaped cutting elements can also have, for example, a circular cross section, since their effective cutting width corresponds to their diameter.
