Leadscrews; Ball Oilers - Grizzly G0727 Owner's Manual

Leadscrews

Oil Type ...... Grizzly H8257 or ISO 68 Equivalent
Oil Amount ......................................... As Needed
Lubrication Frequency ..............Before Operation
Each table axis uses a leadscrew for movement
(see Figures 35–37). Before lubricating the lead-
screws, clean them with mineral spirits and a stiff
brush. To lubricate the leadscrews, use another
stiff brush to apply oil along their exposed length,
then move each table axis through its full length
of travel to evenly distribute the oil.

Ball Oilers

Oil Type ...... Grizzly H8257 or ISO 68 Equivalent
Oil Amount ......................................... As Needed
Pump Oil Can w/Plastic or Rubber Cone Tip .... 1
Lubrication Frequency ..............Before Operation
The two ball oilers shown in Figure 38 are for the
X- and Z-axis leadscrew bushing and bearing.
Proper lubrication of ball oilers is done with a
pump-type oil gun that has a plastic or rubber-
ized cone tip. We do not recommend using metal
needle or lance tips that can push the ball too far
into the oiler, break the spring seat, and lodge the
ball into the oil galley.
When lubricating the ball oilers, first clean the
outside surface to remove any grime or debris.
Push the rubber or plastic tip of the oil can nozzle
against the ball oiler to create a hydraulic seal,
then pump the oil can once or twice. When fin-
ished, wipe away any excess oil.
