Installing the pneumatics
WARNING
Risk of injuries through leaking compressed
air and lashing pneumatic hoses
Open or loose pneumatic connections can cause
severe injuries.
during installation and main-
Ensure that
tenance
of the pneumatic hoses and of the com-
pressed air regulator compressed air is not
conducted through the hoses and connections.
Before
conducting compressed air through the
hoses and connectors, verify that the hoses are
securely inserted into the correct connectors and
that they are not damaged. This also applies to the
compressed air regulator.
Do not conduct compressed air through damaged
hoses and connectors.
NOTICE
The spindle may suffer bearing damage
and electrical damage if the compressed air
is contaminated
The incoming compressed air must be dry and oil-free
according to ISO 8573-1:2010 because the
compressed air regulator only serves as an
for contaminated air.
Air purity according to ISO 8573-1:2010
Solid class 3 Filtration degree better than 5 µm
particles for solid particles
Water class 4 Maximum pressure dew point
content +3 °C
Residual oil class 3 Maximum oil content: 1 mg/m
content
Ensure that the compressed air meets the above
requirements.
Only connect the machine to the compressed air
supply if the compressed air regulator is properly
installed.
The machine requires the compressed air for the
following tasks:
For the opening and closing of the collet chuck
n
during tool changes.
Air consumption (ionizer deactivated): approx. 50
l/min at 6 bar, 65 l/min at 8 bar (1.8 cfm at 90 psi, 2.3
cfm at 120 psi)
Air consumption (ionizer activated): approx. 100
l/min at 6 bar, 110 l/min at 8 bar (3.5 cfm at 90 psi,
3.9 cfm at 120 psi)
