Calibrating the axes
NOTICE
Deterioration of machining results caused
by an incorrect calibration
At delivery, your machine is already calibrated. As
long as your machining results are accurate, a new
calibration 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 adjust-
ing the machining conditions first: Check the fix-
ation 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
calibration.
By calibrating the machine with test and calibration
specimens, it may be possible to improve the
machining results. Customer service will assist you
with this.
Your machine is delivered with a calibration set.
Customer service will need this set for calibration. It
contains the following parts:
n
Calibration blanks which are used to mill cal-
ibration and test specimens
n
A tool for milling the calibration or test spe-
cimens
n
A micrometer for measuring the machining pre-
cision
Replacing the tool magazine
inserts
When tool magazine inserts are worn, they should be
replaced. New inserts are delivered without holes for
the tools. The holes must be drilled into the inserts
with the machine.
n
Your machine comes with tool magazine inserts
as spare parts and with the drill tool.
n
Additional inserts and drill tools are available via
customer service.
Customer service exchanges the tool magazine inserts
during preventive maintenance. If required, you can
exchange tool magazine inserts yourself and have
customer service drill the holes into the inserts via
remote maintenance.
You can replace tool magazine inserts as follows:
1.
Contact customer service. They will assist you
with drilling the holes into the new inserts. Other-
wise, you wont be able to insert tools into the
tool magazines.
2.
Remove all tools from the desired magazine.
3.
Remove the screws from the bottom of the tool
magazine and put them aside.
4.
