Managing tools
NOTICE
Damaging of the spindle or the tool
positions if you use improper tools
Improper tools can damage the collet chuck of the
spindle and / or the tool positions.
Only use tools with a sufficiently large chamfer at
the tool shank.
Install a retaining ring as a stop ring according to
DIN 471-A3.
Only insert tools with a maximum diameter of
3mm at the thickest part into the collet chuck.
Only insert tools with a maximum cutting edge dia-
meter of 2.6 mm into the tool magazine.
We recommend original tools as they are
designed especially for the designated jobs.
The machine uses exchangeable tool magazines that
can hold up to 6 tools each.

You can store magazines that are currently not needed
in the multi-purpose drawer.
A sensor recognizes the tool magazine which is
currently mounted into the working chamber. The
touchscreen displays the required magazine for each
job and whether it is mounted into the working
chamber.
The machine can change tools automatically during
machining so that it executes jobs without your inter-
ference.
If tool magazine inserts are worn, you should
replace them. (
