Definitions

  • the invention relates to a grinding wheel for the surface processing of workpieces, consisting of an annular grinding body.
  • Grinding wheels can have a non-uniform mass distribution around the axis of rotation due to different abrasion of the grinding wheel material, which leads to imbalance of the grinding wheel.
  • Other reasons for imbalance of the grinding wheel can be differences in geometry, eccentric grinding wheel seat and inhomogeneous structure of the grinding wheel. Such imbalances affect not only the bearing of the grinding wheel, but also the quality of the surface treatment of the workpieces.
  • balancing masses in the form of balancing weights or balancing liquids which, as an additional device, for example in the form of a so-called balancing head, are connected in a rotationally fixed manner to the grinding wheel and rotates with it during the grinding operation (Hofmann-News 6, Impr. 06.84 D).
  • the object of the invention is to provide a grinding wheel of the type mentioned, in which the mass balancing devices required for the unbalance compensation can be easily trained.
  • the grinding wheel of the type mentioned at the outset is characterized in that the grinding wheel body has one or more cavities which are arranged rotationally symmetrically about the grinding wheel axis and are designed as receiving spaces for balancing masses which serve to compensate for imbalance.
  • the cavities can be designed as guide means for movable counterweight bodies which can be displaced in the radial and / or circumferential direction in the annular grinding body with respect to the grinding wheel axis.
  • the balance weight body can be made of the same material, e.g. Corundum like the grinding wheel.
  • the cavities in the grinding wheel can also be arranged as liquid receiving chambers in the circumferential direction in the interior of the grinding wheel.
  • the cavities in the grinding wheel are preferably arranged such that the balancing masses are arranged symmetrically with respect to the center plane of the grinding wheel with regard to their mass distribution.
  • the exemplary embodiments shown in the figures have an annular grinding body 1.
  • This grinding body can consist of corundum or another abrasive material.
  • the grinding wheel 1 is fastened to a grinding wheel holder for the grinding operation. During the grinding operation, the grinding wheel rotates around the grinding wheel axis A.
  • counterweight body 3 in the embodiment shown 2 counterweight body
  • the balance weight body 3 can be displaced in the circumferential direction around the axis A of the grinding body.
  • an annular cavity is provided on the grinding body 1, starting from its inner circumference, which receives the counterweight body 3 and serves as a guide means for the counterweight body.
  • the counterweight bodies 3 can be guided in the cavity 2 in such a way that they are arranged symmetrically to the center plane ME of the grinding wheel in each position.
  • each counterweight body 5 is arranged in cavities 4 which extend radially with respect to the grinding body axis A.
  • the counterweight 5 are movably guided in the radial direction.
  • compensation chambers which can be filled with a compensation liquid 8 are provided in the grinding wheel body 1 in the vicinity of its inner circumference.
  • inlet slots may be arranged on different radii on one of the two end faces of the grinding body, as is the case with the annular expansion tank of the additional compensation device, which is known from DE-OS 23 57 629.
  • the chambers 6 are covered, for example, by the material of the grinding wheel holder, which is not shown in detail.
  • the cover contains inlet openings for the compensation liquid to be supplied to the chambers 6.
