Definitions

  • the invention relates to a grinding wheel for grinding curved Surface sections and an intermediate and using a method for producing such a grinding wheel the features of the preamble of the independent claims.
  • grinding flat surfaces becomes flat Discs used with abrasives on one or both sides is applied.
  • the grinding wheel essentially consists of a supporting body and abrasive applied to the support body.
  • abrasives become particularly flexible Understand flat support provided with abrasives is typically a sanding belt or sections a grinding belt or a flat grinding wheel. But it is also conceivable, abrasives directly and without a carrier on the Apply body, especially abrasive material directly to glue on the support body.
  • the grinding wheel can be rotated about an axis, for example through a grinder.
