Installing the abutment holder
Installing the MIT Pre-Mill® abutment holder
- Open the working chamber door.
- Remove the blank from the blank holder if present.
- Correctly orient the MIT Pre-Mill® abutment holder:
- The 3 positioning pins must be inserted into the drillings of the MIT Pre-Mill® abutment holder.
-
Insert the MIT Pre-Mill® abutment holder into the blank holder.
- Push the MIT Pre-Mill® abutment holder into the blank holder as far as possible.
- To fixate the MIT Pre-Mill® abutment holder, screw the 2 cylinder screws into the blank holder with the provided allen key.
You can equip the abutment holder with a maximum amount of 2 prefabricated abutments type MIT Pre-Mill®.
Mounting MIT Pre-Mill® abutments
You can mount Pre-mill® abutments to the abutment holder as follows:
- Loosen the screw of the abutment position of the Pre-mill® abutment holder. Push down the screw to widen the gap between the 2 parts of the Pre-mill® abutment holder.
- The according abutment position is open.
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.
-
Push the Pre-mill® abutment into the holder until it is properly seated. Mind the positioning aids on the respective abutment (marked orange) and in the abutment position (marked blue).
-
If the abutment is positioned correctly, the markings are in one line with the joint between the 2 parts of the abutment holder.
-
- Re-tighten the respective screw of the ® abutment holder.
- The ® abutment is mounted.
