PrograMill Dry – Maintenance and do-it-yourself

Exchanging the main fuse

The internal power supply of the machine has a main
fuse that is accessible from the outside and can be
replaced if necessary.
As a replacement fuse, only use a fuse of the fol-
lowing type: T6.3A L250V
1. Switch off the machine at the main power switch.

the replacement fuse from the right side of the
fuse cover and put it into the left side of the fuse
cover.
6. Remount the fuse cover.

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 cali-
bration is not necessary. A calibration takes much time
and will deteriorate the machining results if it is improp-
erly executed.
In case of inaccurate machining results, try adjust-
ing the machining conditions first: Check the fix-
ation and quality of the material and the state of the
tool.
Before calibrating the machine, contact your autho-
rized service partner.
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.
Your machine is delivered with a calibration set. It
contains the following parts:
( )
MARKED ORANGE
Operating Instructions: PrograMill Dry Version: 2/19/2021
Calibration discs which are used to mill cal-
n
ibration or 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 disc into the material holder.
3. Follow the instructions on calibrating the machine
in the documentation for PrograMill CNC.
4. Keep all parts of the calibration set except used
calibration discs for further use.

Replacing the tool magazine inserts

If tool magazine inserts are worn, you should replace
them. New inserts are delivered without holes for the
tools. The holes must be drilled into the inserts with the
machine.
Your machine comes with tool magazine inserts
n
as spare parts and with the drill tool.
Additional inserts and drill tools are available via
n
authorized service partner.
You can replace tool magazine inserts as follows:
1. Have the spare tool magazine inserts readily avail-
able.
2. Open the working chamber door.
3. Remove all tools from the tool magazine.
4. Unscrew the 4 screws on the upper side of the
tool magazine and lift the cover.
