5.2 Maintenance
5.2.1
Gib Adjustments
The objective of adjusting the gibs is to eliminate as much play in the cross slide and carriage sliding
surfaces as possible without having the tightness of the gib interfere with their free movement and
cause a decrease in the accuracy and/or performance of the machine due to excessive friction.
5.2.1.1
Cross Slide Gib Adjustment
1.
Remove the yoke bolts from the top of the cross slide and slide it back and forth and feel for
any looseness in the system. If it is loose tighten up the adjusting screws.
NOTE:
Adjustments should be made where the gibs are worn the worst.
2.
Turn the X-axis ball screw with a torque wrench and measure the torque. The torque should be
less than 15 in/lb. and consistent over the travel of the X-axis. If the measurement is higher
than this then loosen the gib. Make sure the cross slide is aligned properly. One easy way to
check for this is to remove the yoke bolts and see if the yoke springs back into position.
Misalignment is also evident if the torque is higher when the yoke is up against the rear bearing
housing.
