Maintenance unit

The spindle is equipped with a sealing-air feature.
This sealing air prevents shavings/chips and dust
from entering the spindle. The service unit filters
possible contamination in the sealing air and thus
prevents costly machine damage.

▷ Mount the service unit on the rear side of the
machine using the screws.
▷ Connect the 250 mm compressed-air hose [3]
to the right-hand connection of the service unit
and to the compressed-air connection [5] of the
milling machine.
▷ Connect the 2000 mm compressed-air hose to
the compressed-air inlet [1] of the service unit
and the other end to the compressed-air supply
of the laboratory.
Requirements for the compressed-air supply
For operation, the compressed air must fulfil the
following minimum requirements:
_ Flow rate: 50 l/min (1.77 CFM)
_ Pressure: 6 bar / 87 psi
Requirements on air purity:
_ Solid contaminants: Class 3;
better than 5 μm for solids
_ Water content: Class 4;
Max. pressure dew point +3 °C
_ Total oil content: Class 2;
Max. oil content 0.1 mg/m
In continuous operation, the pressure and the air-
flow rate are monitored by the milling machine.
When the required values are fallen below, the
milling program stops. Once the correct air values
are available again, the milling program can be
continued after fault acknowledgement in the
software.
