Definitions

  • the intermediate layer 30 is preferably arranged between the base 20 and the polishing foil 40.
  • the polishing foil 40 is connected to the base 20 by means of the intermediate layer 30.
  • the polishing tool 10 and/or the base 20 and/or the intermediate layer 30 are/is at least essentially rotationally symmetrical.
  • the workpiece L is preferably fixed/attached to a workpiece carrier (not shown), in particular by means of a block piece (not shown).
  • a polishing process in the sense of the present invention means in particular the complete polishing of the processing surface LF to be polished of the workpiece L with the polishing tool 10.
  • the smaller radius of curvature results in the polishing tool 10, in particular the intermediate layer 30, being more strongly compressed in the deflected and/or eccentric/off-center processing position at the edge of workpiece L, in Fig. 3D on the right, than in the center of the workpiece L.
