4.2 Safety
The milling machine must only be operated under the following conditions:

The milling machine is in proper working order.

The milling machine is used as intended.

The operating instructions are followed.

All safety devices are installed and activated.
Eliminate or have all malfunctions rectified promptly. Stop the milling machine immediately in
the event of any abnormality in operation and make sure it cannot be started up accidentally or
without authorisation.

4.3 Switching the milling machine on

Select the gear stage

Close the spindle protection system.

Set speed regulator to lowest speed.

Actuate the push button "ON".

Select the direction of rotation.

Set desired speed on the speed regulator.
4.4 Switching off the drilling milling machine

Press the softkey “Off”. For a longer-term standstill, switch it off at the main switch.
CAUTION!
Only press the emergency stop button in a genuine emergency. You should not use the
emergency-stop button to stop the machine during normal operation.
4.5 Resetting an emergency stop situation

Unlock the emergency stop switch again.

Switch on the spindle rotation again.
4.6 Power failure, Restoring readiness for operation

Switch on the spindle rotation again.
4.7 Speed setting
4.7.1 Selecting the speed
The correct speed is an important factor for milling. The speed determines the cutting speed by
which the cutting edges cut the material. The service life of the tool can be increased and the
working result optimized by selecting the correct cutting speed.
The ideal cutting speed basically depends on the workpiece and the tool material. Higher
speeds are possible with tools (mills) made from hard metal or cutting ceramics than with tools
made from high-alloy high speed steel (HSS). You will achieve the ideal cutting speed by se-
lecting the correct rotation speed by hand.
We recommend using a machining technology paperback
ISBN 978-3-8085-1473-3 (example, only in German language available). In these reference ta-
ble books you will find all the necessary and additional information. These machining technolo-
gy reference table books should bridge the gap between the predominantly theory-oriented
textbooks and reference & reference table books mostly written with the few theoretical princi-
ples in practice.
