NOTICE

Damaging of the spindle or the tool positions if you use improper tools

Inappropriate tools may damage the spindle collet chuck and/or tool positions.

  • Use only tools with a sufficiently large chamfer on the tool shaft.

  • Install a retaining ring as a stop ring according to DIN 471-A3.

  • See the further instructions in chapter Technical data.

Automatic or manual tool change

Tool change can take place automatically via the tool magazine or manually via the collet chuck. Since each tool position can be configured individually, automatic and manual changes are possible in parallel.

Automatic tool change properties

  • The machine automatically loads the necessary tools from the magazine during machining.

  • You must insert all required tools into the tool magazine before the job begins.

  • Default case for all tool positions where no manual change is configured in DentalCNC.

Automatic tool change is not possible in the following cases:

  • A tool position is worn out and can no longer hold any tools properly.

  • You use tools which do not fit into the tool magazine.

Manual tool change properties

  • During the application, you manually insert the tools into the spindle’s collet chuck at the request of DentalCNC.

  • You must configure this manual tool change for individual tool positions in DentalCNC.

  • This is described in the DentalCNCmanual.

Inserting tools into the tool magazine

You can equip the tool magazine of your machine in two ways:

  • By manual insertion into the tool magazine This is the fastest way. It is described below.
  • About the spindle You insert a tool into the collet chuck and the spindle places the tool in the tool magazine. This option takes more time, but might be more convenient for some. It is described in the documentation for the manufacturing software.

You can insert up to 8 tools into the tool magazine. The tool magazine is removable.

Tool magazine in the working chamber (marked orange)

You insert tools manually as follows:

  1. CAUTION!Wear gloves.

  2. Open the working chamber door.

  3. If you want to equip the tool magazine outside of the machine, pull the tool magazine out of the working chamber by the recessed grips (marked blue).

    4.  

  4. NOTICE! Remove worn or damaged tools from the tool magazine if any. DentalCNC shows the tool life in the Tool management view.

  5. Insert the new tools:
    1. Ensure that the positions of the tools in the tool magazine match the tool positions in DentalCNC.
    2. Insert the tools in the tool positions with the edge facing downward. Push them in until the ring touches the rubber.

    If the positions of the tools in the tool magazine do not match the tool positions in DentalCNC, the machine will use the wrong tool(s) during job execution and the job result will become unusable.

  6. After replacing a tool, reset the tool life value. For this, use the Tool management view in DentalCNC.
  7. Plug the tool magazine back onto the tool magazine holder if required.

Removing tools from the tool magazine

  1. CAUTION!Wear gloves.

  2. Open the working chamber door.

  3. Pull the tool upward out of the tool magazine.

  4. Depending on whether you place the tool back in your inventory or no longer use the tool type, configure DentalCNC accordingly:

Adding backup tools

If the tool life of a tool expires during machining, DentalCNC can automatically load a backup tool from the tool magazine to continue machining.

  1. Place backup tools in the tool magazine.

  2. Configure the backup tools in DentalCNC.
