Definitions

  • the invention relates to a dressing tool.
  • the main function of dressing tools in the machining of grinding wheel work surfaces is on the one hand to remove blunt abrasive grains and metal particles that clog the grinding wheel work surface during use, and on the other hand to restore the correct geometric shape of the grinding wheel. It has long been known to use diamond tools as dressing tools.
  • diamond tools There are diamond single and multigrain dressers, diamond dressing blocks and diamond dressing rollers. If a dressing block is used, it can pass under the grinding wheel, whereby the removal can take place in several passes with little depth infeed.
  • Diamond dressing rollers perform a rotational movement and preferably a relative movement to the grinding wheel, which is also rotating, when dressing grinding wheels, the rotating movement preferably being able to take place via a separate drive in both directions of rotation.
  • the positive and negative processes are known in the manufacture of diamond dressing rolls.
  • diamond grain is applied to a dimensionally accurate base body and bound by means of galvanic metal precipitation.
  • diamond dressing rolls can only be manufactured with limited accuracy.
  • With the negative process better shape accuracy is achieved. So are in a form ring, the inner shape of which corresponds exactly to the dressing roller to be produced; Diamonds introduced by hand and with galvanic metal deposit or sintered metal and then bound in various ways. After removing the form ring, a dressing roller is created, the outer contours of which correspond exactly to the desired profile.
  • Different types of dressing rollers can be produced by using different diamond grain sizes and manufacturing techniques as well as different metallic or plastic bonds. With a few exceptions, the diamond dressing rollers are only covered with a single diamond grain layer, which covers the entire surface of the dressing roller, i.e. forms a closed surface.
  • a dressing tool is to be created, the infeed of which in relation to the grinding wheel to be machined is increased many times over in comparison to the known dressing tools in order to significantly reduce the dressing time.
  • the profile of the dressing tool is formed by spaced profiled plates made of hard or superhard material. It is preferably the hard one or superhard material polycrystalline synthetic diamond or cubic crystalline boron nitride or hard metal, for example in the form of tungsten compounds or titanium compounds or ceramics, wherein in one embodiment of the invention the plates consist of a compact unit of the hard or superhard material or of a base body provided with a coating of the material and having the profile consist. If coated base bodies are used as profiled plates, known methods, such as, for example, electrolytic application or vapor deposition, can be used, which are used for diamond or hard metal or ceramic cutting materials.
  • a dressing tool according to the invention in the form of a dressing roller is characterized by segments spaced apart on the circumferential surface of a shaft body, for example in the form of teeth, on the breast surfaces of which the profiled plates made of hard or superhard material are provided.
  • the profile of the dressing roller is preferably composed of the front surfaces of the profiled plates made of hard or superhard material, preferably two teeth. This is particularly advantageous if a breast surface of a tooth is composed of several profiled plates made of synthetic diamond, provided that these are not available in any dimension.
  • the profiled plates of successive teeth are then offset from one another in order to achieve an overlap. This has the advantage that the impact of adjacent plates is not noticeable when dressing.
  • chip chambers are arranged in front of the chest surfaces in the shaft body in order to be able to accommodate the metal particles and abrasive grains that occur during machining of the grinding wheel, since otherwise complex devices would have to be removed.
  • a dressing tool in the form of a dressing block it is proposed according to the invention to arrange profiled plates made of hard or superhard material on a base body at a distance from one another and on projections and which form the profile of the dressing block.
  • the profile surface is preferably formed by profiled plates made of hard or superhard material arranged on at least two projections, provided that more than one plate forms the front surface of a projection.
  • the plates are produced by means of spark erosion or by means of an electron or laser Jet or a hot oxygen jet or by grinding or shaping, for example processed by pressing.
  • a dressing roller 10 which consists of a base or shaft body 12, which in the exemplary embodiment has eight segments 14. Tungsten carbide plates 16 are arranged on the chest surfaces of the segments 14. A carrier material 20, which serves to hold profiled 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.
  • FIG. 2 illustrates, there is often more than one diamond plate 18 (filled area) on a chest surface of a segment 14 arranged to provide a desired profile. So that the joint between the synthetic diamond plates 18 does not influence the geometric accuracy when dressing grinding wheels, that is, for example, the joint does not lead to an undesired deepening or elevation on the grinding wheel, the diamond plates 18 are arranged offset on one another on successive segments 14. This results in an overlap in the joint area when the dressing roller rotates, so that an extremely precise geometric accuracy of the grinding wheel is still guaranteed. As illustrated in FIG. 2, two synthetic diamond plates 18 are arranged on a segment 22, whereas only a single diamond plate 18 is provided on the following segment 24, which is arranged exactly in the joint area of the plates 18 of the preceding segment 22.
  • a chip chamber 26 is provided in front of the teeth 14, into which the corresponding parts can be accommodated.
  • a complex removal of the corresponding particles is not necessary, as is the case when using known dressing tools with continuous dressing rollers provided with diamond grains.
  • a side view of a truing block 30 is shown having the projections 32, p their chest surfaces Schneidst ffe 34 are arranged.
  • the cutting materials 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 plates 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.
  • Strength in F. 4 is a front view of the invention
  • a b-directing block 30 is shown and illustrates that the profile surface is composed of a projection of a plurality of machined plates hard or hard material.
