  • this is advantageous in that the individual facade panels can be attached to the building independently of their machining direction.
  • the present invention is based on the finding that when the workpiece enters the area of the disc sander, a particularly large force acts on the edge region of the workpiece, with the result that a greater grinding effect is achieved in this edge region than in the remaining part of the workpiece that no uniform sanding image arises.
  • Each of the grinding units rotates about a vertical axis V, V ', the disc grinding units rotate about their own vertical axis Z and the actual grinding plates are mounted eccentrically and rotate about the axis N.

  • the grinding unit rests with the grinding plate on the workpiece and presses the abrasive with its own weight on the workpiece. This has the advantage that when the workpiece strikes the grinding disc, the grinding unit is pushed away upwards and thus a high contact pressure of the grinding means on the edge of the workpiece is avoided.
  • the grinding unit can escape upwards and thus avoid an increase in the contact pressure and thus a change in the grinding pattern.
  • the contact pressure is determined by the weight of the grinding unit, but which is always the same, no matter at which point of the grinding disc is the workpiece, or no matter how irregular the workpiece.
