Backlash
Leadscrew backlash is the amount the leadscrew
rotates before the attached device begins to
move.
Although the mill is equipped with double-
bronzed longitudinal and cross leadscrew nuts to
minimize backlash, leadscrews will always have
a certain amount of backlash that will increase
with normal wear.
Generally, 0.005"–0.010" leadscrew backlash
is acceptable to ensure smooth movement and
reduce the risk of premature thread wear.
However, if you find it necessary to adjust
leadscrew backlash, perform the procedures
listed below.
