Calibrating the machine with a test and calibration specimen may improve 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:

• Calibration blanks which are used to mill calibration and test specimens
• A tool for milling the calibration or test specimens
• A micrometer for measuring the machining precision

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 as spare parts and with the drill tool.
• 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. Otherwise, you won't 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. Firmly press against the tool magazine insert.
• The insert moves out of the magazine together with its retainer.
