Maintenance
With normal use, the portal milling machine should
be lubricated every six months, but at the latest after
twelve months. To do this, proceed as follows:
All greasing points
After lubricating, remove excess grease with a rag.
Note:
As a grease gun, we recommend the HIWIN
grease gun set from the Sorotec online shop
(item no. SM.0014).
Common multi-purpose grease is sucient for
lubricating the spindle nuts and carriages.
Guide carriages X-axis
• Drive the portal to the front stop of the X-axis.
The lubricating nipples of the carriages are now
easily accessible from the front.
• Lubricate on the left and right as shown in
Fig. 44.
• On a machine with a performance kit, repeat
the process from the rear for the rear guide
carriages.

Spindle nut X axis
• Carry out the lubrication as shown in Fig. 45.
Note:
The lubricating nipple of the X spindle nut can
only be reached from below. You can simplify the
greasing process with a maintenance opening in
the base of the machine.
Otherwise, the portal milling machine must be
laid on its side or lifted at the rear to lubricate the
X-spindle nut.
