OPERATION: PREPARING
JOBS
Before you can machine blanks, you need to prepare
the machine. The corresponding jobs must have been
transferred to DENTALCNC where they display in the
job list.
6.1 Starting the machine
NOTICE
Short-circuit hazard when the
machine is too cold
If the machine is transported from a cold environment
into a warmer environment, a short circuit may occur
caused by condensate.
Before
switching on the machine after trans-
portation, ensure the following:
n
The ambient air has the allowed temperature.
n
The machine has the same temperature as the
ambient air. This will take
at least
48 hours.
n
The machine is completely dry.
You usually start the machine as follows:
1. Ensure that the machine is properly installed.
2. Switch on the machine at the main power switch.
3. If the machine controls the suction unit, switch on
the unit and select the necessary extraction level.
The suction unit is not running. If it is, either the
switching unit or the data cable of supported suc-
tion units is not properly installed.
If you control the suction unit manually, you
will switch it on immediately before job
execution.
4. Close the working chamber door.
The machine will not reference if the
working chamber door is open.
5. Start the CAM computer.
6. Start DENTALCNC.
The following happens:
a. The machine references.
b. The working chamber is illuminated in white.
7. If the machine doesn’t reference because the work-
ing chamber door is open, close the door. Wait
until the machine has referenced.
After the machine has referenced, it is operational.
6.2 Starting the machine w ith a tool
in the collet chuck
Under some circumstances like a power outage, there
can be a tool in the collet chuck of the spindle when
you start the machine. You need to remove the tool
from the collet chuck before you can use the machine.
CAUTION
Danger of cuts and burns
when touching tools with
your bare hands
If you handle tools on the cutting surface, you may be
injured. As the tool may be very hot, you may also
suffer from skin burns.
Only touch tools at their shank.
When handling tools, wear protective gloves.
NOTICE
Machine damage if you do not
remove the tool
If the tool remains in the spindle after you have
confirmed the message, it will collide with machine
parts such as the measuring key and severely damage
them.
Always
follow the instructions below when you start
the machine with a tool in the collet chuck.
1. Start the machine.
DENTALCNC displays that there is a tool in the col-
let chuck.
2. Open the working chamber door.
3.
CAUTION!
Wear gloves.
4. Hold the tool in the collet chuck in place.
5. Confirm the current message.
The following happens:
a. The collet chuck opens.
b. The current dialog window closes.
c. A dialog window opens.
6. Remove the tool from the collet chuck.
