Lubrication
between
the ouside of the quill and the bore in
which
it rides
is
effected by
waste
oil
from
the
Z
axis ballscrew.
To distribute and retain the oil on
the
table,
saddle and
knee, grooves
are
cut
into the
face
of
the
ways
and through holes
in
the
gib
so
that both
sides
of
the dovetail
get full
lubrication.
Excess oil exudes
over the
edge
of the
ways
between
the moving members.
Spindle bearings are
grease-packed
and require no
additional lubrication
for
the
life of the
machine.
Low level lube
will not stop a
job
in
progress
but it
will
prwent the
feed
from
being
started
for
the next
job.
