7 OPERATION: EXECUTING
JOBS
You control and start manufacturing with
DENTALCNC. In this chapter, we will give you a brief
overview. For the complete instructions, see the docu-
mentation for DENTALCNC.
NOTICE
blanks
If tools or blanks are damaged, parts can break off and
damage the machine during job execution.
Check the blanks and tools thoroughly for damage
before every job execution.
NOTICE
If the blank holder is open when the machine axes
move, the spindle and the blank holder may get
damaged due to a collision.
Before switching on the machine, executing a job or
moving the spindle via DENTALCNC, close the blank
holder firmly with the left and / or right blank holder
lever.
When you have prepared your jobs and your machine,
you can start machining. Machining is a fully auto-
mated process and only requires your attention in case
of unexpected events.
Do not move the machine during job execu-
tion, otherwise the results may become impre-
cise.

7.1 Starting jobs

1. Ensure the following:
You created a job on your CAM computer. It
n
has been transferred to DENTALCNC.
All required tools are in the right positions in
n
the tool magazine and are neither worn nor
damaged. They have also been added to the
virtual tool magazine in DENTALCNC.
The required blanks are mounted.
n
If you wish to work with ionizer: the option
n
Ionizer activated in DENTALCNC is activated.
The compressed air supply is set correctly.
n
2. Close the working chamber door.
3. If you manually control the suction device, switch it
on and set it to the required level.

4. Start machining via the depicted icon in
DENTALCNC.

7.2 Aborting machining

You can abort machining as follows:
1. Select the depicted icon.
2. Confirm the current message.
The following happens:
a. Machining stops immediately.
b. You are prompted to select whether the tool in
the spindle can be inserted safely into the tool
magazine.
3. If you want the machine to automatically put the
tool into the tool magazine, confirm the dialog. If
you want to remove the tool manually from the col-
let chuck, answer the question in the negative.
Removing the tool manually is necessary in
case that putting it into the tool magazine
would damage the tool magazine inserts.
Depending on your choice, the spindle either puts
the tool into the tool magazine or moves into the
tool change position. In the latter case, continue
with the next step.
CAUTION
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.
4. CAUTION!Wear gloves.
5. Open the working chamber door.
6. Hold the tool in the collet chuck in place.
7. Confirm the current message.
The following happens:
a. The collet chuck opens.
b. The current dialog window closes.
c. A dialog window opens.
8. Remove the tool from the collet chuck.
