Definitions

  • the present invention relates to a cutting disc with a diameter over 500 mm, which is clamped between clamping flanges, with a mixture of Abrasive grain, binder and optionally fillers from the outer edge of the Cutting disc extends to the center hole, with the cutting disc laterally with Steel sheets or steel mesh is provided (see US 3,898,773).
  • Object of the present invention is therefore to provide a cutting disc, the despite being stable in relation to the diameter of a small disk thickness, wherein At the same time the problems of the known approaches are avoided.
  • the steel sheets or steel mesh are glued to the cutting disc.
  • the steel sheets or steel mesh can thus also in the edge zones of the cutting disc Optionally absorb occurring bending stresses, so that a tumbling effect is prevented.
  • the Steel sheets or steel mesh have a substantially round shape.
  • the inventive method provides that first a steel sheet or steel mesh with a minimum thickness of 0.5 mm and with a radial extent of Clamping flanges exceeding extension placed on a Preßptatte, then the mixture of abrasive grain, binder and optionally fillers applied and finally compressed, so that the steel sheet or steel mesh is inserted flush in the side surface.
  • This manufacturing process is Production technology particularly favorable and at the same time ensures a firm hold the Steel sheets or steel mesh.
  • This hold can be further improved by using the steel sheets or Steel grid before pressing on the side facing the blade with a Glue, in particular epoxy glue, be provided.
  • the cutting disc 1 shown in the figures is a Resin-bonded grinding wheel.
  • a resin various phenolic resins used by their targeted selection in conjunction with the choice of Abrasive and the fillers the grinding behavior and the degree of hardness of Cutting disc is adapted to the respective requirements.
  • abrasives are preferred conventional abrasives such as silicon carbide and Corundum used.
  • fillers are mainly solid lubricants, for example Pyrite and graphite, as well as common powdered materials for plastic reinforcement such Calcium carbonate or glass powder.
  • the diameter d of the cutting wheel 1 is typically between 800 mm and 1800 mm.
  • the ratio of diameter d to width b is over 80, preferably even over 100. This ratio is due to the present Invention be further increased. It should be noted that the width b of the Cutting disc 1 for reasons of clarity in the figures in relation to Diameter d is drawn many times too large.
  • the cutting disk 1 has recesses 3 in the lateral end faces, which are extend over a diameter range of diameter d from 45% to 80%. In the recesses 3, the steel sheets or steel mesh 2 are substantially flush used.
  • the steel sheets or steel mesh 2 have a minimum thickness of 0.5 mm and can be up to 3.0 mm thick, with common values being more likely between 1.0 mm and 2.0 mm lie.
  • the steel sheets form a closed surface, whereas under Steel mesh structures are understood, the recesses, in particular have rectangular recesses.
  • the steel sheets or steel mesh 2 are with glued the remaining blade 1.
  • the steel sheets 2 are round in the embodiment shown, as shown in FIG. 3rd seen. Even if the round shape is favorable for quiet concentricity, are also any other shapes, especially polygons, conceivable.
  • Fig. 1 the two cooperating clamping flanges 5a and 5b are shown, with where the power is transmitted to the cutting wheel 1.
  • the steel sheets or Steel grille 2 cause the introduction of force not only to the area of Clamping flanges 5a and 5b remains limited, but essentially to the extends the entire surface covering the steel sheets or steel mesh 2.
  • the Stabilization of the cutting wheel 1 thus extends radially far outward.
  • the cutting disc 1 has a fabric insert 6. It is a resin-impregnated glass fiber fabric.
  • the fabric insert 6 stabilizes the blade 1 and prevents the formation of stray Slice fragments in case of failure of the disc.
  • the present invention allows to get along with only one or at least a few fabric inserts 6. Also conceivable is a variant without tissue insert. This is insofar advantageous, as in reduction of the tissue layers, the volume of the tissue through Abrasive grain can be replaced, whereby the grinding properties are improved.
  • the preparation of the cutting discs according to the invention is such that from Abrasive grain, synthetic resin and fillers a mixture is made. On a round Press plate is first placed a steel or steel mesh 2 and then the Mixture of abrasive grain, synthetic resin and fillers applied. In this mixture the fabric inserts 6 are inserted. Then it is compressed, taking at the Surface is formed a recess 3. In this recess 3, the second Steel plate or steel grille 2 inserted, after which a further pressing takes place. The steel sheets or steel mesh 2 are applied to the before processing Cutting disc 1 facing side provided with an epoxy adhesive.
  • the pressed sandwich is then clamped between straightening plates and in Oven cured at a suitable temperature.
