Deterioration of machining
NOTICE
results caused by an incorrect
calibration
At delivery, your machine is already calibrated. As long
as your machining results are accurate, a new calib-
ration is not necessary. A calibration takes much time
and will deteriorate the machining results if it is
improperly executed.
In case of inaccurate machining results, try adjusting
the machining conditions first: Check the fixation
and quality of the blank and the state of the tool.
Before calibrating the machine, contact customer
service.
Be very careful when measuring and entering data
during calibration. When in doubt, abort the cal-
ibration.
By calibrating the machine with test and calibration
specimens, it may be possible to improve the
machining results.
The documentation for the manufacturing soft-
ware contains all information on calibrating the
machine. Therefore, you will only find inform-
ation specific to this machine in this document.
Your machine is delivered with a calibration set. It
contains the following parts:
Calibration blanks which are used to mill cal-
n
ibration and test specimens
A tool for milling the calibration or test specimens
n
A micrometer for measuring the machining pre-
n
cision
You can calibrate the machine as follows:
1. Have the calibration set readily available.
2. Mount the calibration blank into the blank holder.
3. Follow the instructions on calibrating the machine
in the documentation for DENTALCNC.
4. Keep all parts of the calibration set except used cal-
ibration blanks for further use.
For mounting the blanks for calibration and test speci-
mens in the working chamber, you need to prepare
the blanks:

If the blank is not properly seated in the blank holder,
the measurement results may become incorrect or the
tool may break when calibrating.

NOTICE
results caused by loose screws
Screw the shafts tightly into the blanks.
Screw the blanks tightly into the blank holder.
1. Insert the shafts into the recesses in the blank and
align the openings for the screws with the respect-
ive openings in the blank.
2. Place the screws in the openings of the blank and
screw down the shafts tightly.
