Backlash Adjustment

Backlash is the amount of free play felt while
changing rotation directions with the handwheel.
This can be adjusted on the compound rest and
cross slide leadscrews. Before beginning any
adjustment, make sure all associated compo-
nents are cleaned and lubricated, and the locks
are loose.
Reducing backlash to less than 0.002" is
impractical and can lead to accelerated wear
to the leadscrew and other components.
Avoid the temptation to overtighten the
backlash nut or screw while adjusting.
Compound Rest
Tools Needed:
Hex Wrench 5mm .............................................. 1
Open-End Wrench 10mm .................................. 1
The compound rest backlash is adjusted by loos-
ening or tightening the nut and set screw shown in
Figure 87 to remove play between the handwheel
and the leadscrew collar.

To adjust the backlash, loosen the compound rest
nut and set screw, turn the handwheel counter-
clockwise until the compound rest moves, then
tighten the nut until the backlash is approximately
0.002"–0.003", as indicated on the graduated dial.
Tighten the set screw to secure the setting.

Cross Slide
Tools Needed:
Hex Wrench 4mm .............................................. 1
Hex Wrench 5mm ............................................. 1
Open-End Wrench 14mm .................................. 1
The cross slide backlash is adjusted by loos-
ening the cap screw shown in Figure 88. The
screw pushes down on a wedge and forces the
leadscrew nut apart, taking up lash between the
nut and leadscrew.

To adjust the backlash, remove the compound
rest. Then, rock the cross slide handwheel back
and forth, and tighten the cap screw slowly until
the backlash is approximately 0.002"–0.003" as
indicated on the graduated dial.
Set Screw
If you end up adjusting the nut too tight, loosen
the cap screw, turn the handwheel back and forth
until it turns freely—then try again.
Re-install the compound rest when you are fin-
ished.
