  • a double surface grinding machine with a transport disc which has three workpiece holders for receiving a workpiece.
  • the workpieces are movable between two grinding wheels of the grinding machine.
  • the previously known grinding machine has an auxiliary drive, which is a rotary drive of the three workpiece holders relative to the Transport disc allows.
  • the additional drive has a central support element, on which three drive rollers are arranged, which are each engageable in operative engagement with one of the three workpiece holders.
  • auxiliary drive has three different drive units, which are each assigned to a workpiece holder and each independently separately switched on and off.

  • the auxiliary drive according to the invention makes it possible to drive a first subset of the workpieces received in the transport device relative to the transport device, while at least one further subset of the workpieces is out of operative connection with the auxiliary drive and thus does not move relative to the transport device.
  • the belt transmission makes it possible to change the subsets mentioned depending on the position of the transport device, without changing the course of the belt transmission. This leads to a considerable simplification of the structure of the auxiliary drive.
