Safety devices and recommendations

In order to make working with our drilling and milling machines safe, we have equipped them with
the following safety devices and thus they are in accordance with the relevant European safety
regulations.
1. Protective cover
The separating safety device attached to the machine housing, prevents reaching in and
coming into contact with the tool spindle. This safety device is constructed in such a way that it
can be adjusted to the necessary working height (depending on the dimensions of the
workpiece and tool).
2. Main switch with low voltage release
In order to disconnect the electrical parts of the drilling and milling machine safely from the
mains, we have provided a main switch with low voltage release besides the mains lead with
plug. This undervoltage release prevents the drive motor from coming on after a power cut and
so excludes the danger of the work spindle moving unexpectedly.
3. Emergency OFF switch
This enables a quick interruption of dangerous movements, in particular of the CNC
equipment.
4. Overload protection
This device has been developed to protect the drive motor and it must be noted that after the
motor has been turned off (by hand or automatically), because of overloading, a short pause of
1-3 seconds must be observed before turning the machine on again so that the relay of the
electronical parts can re-establish the closed circuit condition.
5. Safety machine cabin
During the CNC operation the door of the safety machine cabin must be closed. On the right upper
side there is a limit switch that is operated by closing the door. This is the only way to move the
feed motors at the axes independently via the controller.
Only with the door closed
independently via the CNC-controller. When the door is open, the motors are being switched off
the power supply which enables manual operation. The main spindle can be swichted on either
when the door is closed or opened.
Working in manual mode
When switching from manual operation to CNC mode please proceed as follows:
