Cross-Slide Screw to Brass Nut & Nut to Saddle
If there is still excess backlash after the previous adjustment, the backlash is either
between the cross-slide screw and the brass nut or between the brass nut and the
saddle. The following procedure covers both adjustments.
Step 1: Remove the rear support on the backside of the cross-slide table.
Step 2: Loosen the allen bolt that locks the brass nut into the saddle. (See Figure 5.23)
Step 3: Use the handwheel to move the cross-slide table toward the operator side of
the machine. Watch under the table from the backside and stop before the cross-slide
screw comes out of the brass nut.
Step 4: Slowly tighten the four adjusting screws on the brass nut, one at a time, until
a slight drag is felt while turning the cross-slide handwheel. It is best to continue
turning the handwheel back and forth while adjusting the nut to balance ease of
operation and backlash.
