Definitions

  • the present invention relates to a separating or grinding wheel according to the preamble of claim 1.
  • Such cutting or grinding wheels are used to process, for example, stone or concrete, in particular to separate.
  • the cutting teeth which are preferably distributed uniformly over the circumference in the same shape and size, are covered with diamond segments which form a cutting edge.
  • Two cutting teeth are separated by a radial, slot-shaped notch, which opens into a through hole, are discharged through the cooling water and / or cuttings.
  • This through-hole may have an equal or larger diameter than the subsequent notch.
  • these through holes serve to reduce stresses that occur during operation of the separating or grinding wheel, in particular by so-called micro-strokes.
  • the present invention is therefore based on the object to develop a separating or grinding wheel of the generic type so that their life increases and thus the operating costs are reduced.
  • the two, a through hole bounding reductions are the same, that is, both in terms of their sinking angle as well as their sinking depth.
  • the latter can be chosen so that forms a bridge between the two subsidences. It is also conceivable a sharp-edged training, which then results when a reduction is performed directly to the other reduction. In any case, an optimization of the force department is achieved with the exclusion of cracking.
  • the new cutting and grinding wheel is characterized by a much longer compared to a state of the art, in which then the wear of the cutting segments is the determining criterion.
  • a cutting or grinding wheel having a circular blade 1, preferably made of sheet steel, at the peripheral edge of a plurality of cutting teeth 2 are arranged, which are the same shape and dimension and uniformly distributed over the peripheral edge.
  • Each cutting tooth 2 is equipped with diamond segments 5, which form a cutting edge in their entirety.
  • a radially extending, slot-shaped notch 3 is provided which widens outwardly in the region of the diamond segments 5 and, on the other hand, opens into a through-bore 4, which is introduced into the blade 1.
  • the diameter of the through-holes 4 is greater than the width of the adjoining notches 3.
  • each through-bore 4 has a countersink 6 on both sides, which can be seen particularly clearly in FIG.
  • the mirror-symmetrical countersinks 6, relative to the center axis of the through hole 4 extend at an angle of 45 °, so that the two opposing bevels of a countersink 6 form an angle of 90 °.
  • other included angle sizes for example 120 ° or 60 °, are also conceivable.
  • the two opposing counterbores 6 are inserted the same depth and dimensioned in depth so that a web 7 forms between them, which defines the clear diameter of the through hole 4.
  • a bridge 7 can also be formed a sharp edge when a reduction 6 is guided to the beginning of the opposite countersink 6.
  • transition region of each reduction 6 to the associated outer side of the sheet 1 may be formed edged or slightly rounded, as required.
