Gib Adjustments - Grizzly G9972Z Owner's Manual

Gib Adjustments

the gibs on the Model g9972z control the accu-
racy of the cross slide and compound slide move-
ments. these gibs are sliding plates that either
increase or decrease pressure on the sliding
components around them.
the goal of gib adjustment is to remove unneces-
sary sloppiness without causing the ways to bind.
tight gibs make the movements more accurate,
but harder to perform. Loose gibs make the move-
ments sloppy, but easier to perform.
NOTICE
Excessively loose gibs may cause poor
workpiece finishes, and may cause undue
wear of the sliding surfaces and ways.
Over-tightening the gibs may cause prema-
ture wear of these sliding surfaces.

nuts and set screws.
Make adjustments in small and equal incre-
ments to the three set screws, then test
the movement of the slide by rotating the
handwheel.
Note: Turning the set screws clockwise will
tighten the gib, and turning them counter-
clockwise will loosen the gib.
When you are satisfied with the gib adjust-
ment, keep the set screws from moving and
re-tighten the hex nuts to secure the set-
tings.
re-check the movement of the slide and, if
necessary, repeat Steps 2–4.
