Lubrication
Other than the lubrication points covered in this
section, all other bearings are internally lubricated
and sealed at the factory. Simply leave them
alone unless they need to be replaced.
One-Shot Oiler
Type ............Model T23963 or ISO 32 Equivalent
Amount .............................................. 1–2 Pumps
Lubrication Frequency ...... 4–8 Hrs. of Operation
The one-shot oiler provides lubrication to the
vertical leadscrew, the cross feed ways, and the
cross feed leadscrew.
To use the one-shot oiler, pull the pump handle
out (see Figure 45) and push it back in with mod-
erate force. Move the grinding head up and down
a few times through the full Z-axis path to distrib-
ute the oil on the leadscrew. Do the same with the
Y-axis handwheel.
Use the sight glass to check the oil level and fill
when needed.
Oil Sump
As the one-shot oiler sends oil to the cross feed
ways, any excess oil will exit tubes in the rear and
drain into a sump in the column. Check and drain
the sump at least once a month to avoid overflow.
To drain the oil sump, use a 10mm hex wrench to
remove the drain plug on the rear of the column
(see Figure 46).
