Gib Adjustment - Grizzly T10814 Owner's Manual

Gib Adjustment

The goal of adjusting the gib screws is to remove
sloppiness or "play" from the ways without over-
adjusting them to the point where they become
stiff and difficult to move.
In general, loose gibs cause poor finishes and
tool chatter; however, over-tightened gibs cause
premature wear and make it difficult to turn the
handwheels.
The gib adjustment process usually requires some
trial-and-error. Repeat the process as necessary
until you find the best balance between loose and
stiff movement. Most machinists find that the ideal
gib adjustment is one where a small amount of
drag or resistance is present, yet the handwheels
are still somewhat easy to move.

3.
Adjust gib screws in small and equal incre-
ments, then test movement of slide by rotat-
ing adjustment wheel.
Note: Turning gib screws clockwise tightens
the gib, and turning them counterclockwise
loosens the gib.
4.
When satisfied with gib adjustment, use hex
wrench to prevent gib screws from moving,
then retighten hex nuts to secure settings.
5.
Recheck movement of slide and, if neces-
sary, repeat Steps 2–4.
