9.2 Machine-specific notes

9.2.1 Loud machining noise

The actual sound emission of the machine varies
heavily depending on the manufacturing material and
the machining conditions.
If the machine is exceptionally loud, check the fol-
lowing operating conditions:
Cleanliness of the blank holder
n
Condition of the tools
n
Quality of the blank
n
If loud noise cannot be avoided, wear ear pro-
tection during machining.
9.2.2 How to proceed in the event of a
machine malfunction
A machine malfunction was recognized by the internal
control unit in case of a critical event. The working
chamber will be illuminated in red. DENTALCNC
displays the error message and error code that was
sent by the control unit.
1. Record the error message and error code that is dis-
played.
2. Restart the machine and the CAM computer. If the
3. Disconnect the machine from the electrical source
4. Contact customer service. Have the error message
5. To remove a blank from the working chamber,
9.2.3 How to proceed in the event of a tool
breakage
If a tool breaks during machining, the machine will not
recognize this immediately. Instead, the spindle will
continue to move with the broken tool. The tool
breakage will be recognized upon the following
events:
A tool breakage can be caused by the following:
If a tool breaks, do the following:
1. Open the working chamber door.
2. Remove all parts of the broken tool from the work-
3. Re-add the tool to the virtual ATB and virtual tool
4. If the spindle picked up the tool from the tool
5. If you manually inserted the tool into the collet
6. Close the working chamber door.
7. Resume the job.
