NOTICE

Bad machining results caused by incorrect scanning of prefabricated abutments

If there is moisture or dirt on the prefabricated abutments, the machine will scan them incorrectly. The machining result will become unusable as a result.

  • Wipe over the bellow before you insert prefabricated abutments so that no cooling liquid drips onto them.
  • Clean the prefabricated abutments with a dry, lint-free cloth before processing.

  1. Push the PreFace abutment into the holder until it is properly seated. The base of the blank must point with its flat part (marked blue) towards the screw of the slot (marked orange).
