Cross Slide

Backlash Adjustment

Backlash is the amount of play found in a lead screw. It can be found by turning the cross slide handwheel in one direction, and then turning the handwheel the other direction. When the cross slide begins to move, the backlash has been taken up.

Note: Avoid the temptation to overtighten the cross slide backlash screw. Overtightening will cause excessive wear to the sliding block and lead screw.

Backlash is adjusted by tightening or loosening the screw shown in Figure 54.

screw.

This screw draws a wedge-type nut against the lead screw and main nut. If you get it too tight, loosen the screw a few turns and tap the cross slide a few times with a rubber or wooden mallet. Then turn the handle slowly back and fourth until the handle turns freely. To readjust the backlash, rock the handle back and fourth and tighten the screw slowly until the backlash is at approximately 0.001" to 0.002" as indicated on the handwheel.

Note: Reducing backlash to less than 0.001" is impractical and reduces the life of the cross slide.

Gib Adjustments

When adjusting gibs (Figures 55 and 56), keep in mind that the goal is to remove sloppiness in the ways without causing the slides or half nut to bind. Loose gibs will cause a poor finish on the workpiece and wear the slide. Over-tightening will damage the slide, lead screw, and half-nut. The cross slide gib is a tapered piece of iron. When the opposing front and rear gib adjustment screws are turned in opposing directions, the screws force the tapered gibs to fill the void in the way, thus tightening the play in the cross slide. If more play is needed turn the screws the other direction.

For the four saddle gibs, (Figure 55) loosen the jam nuts and turn the three set screws until slight tension felt and the gib plates are slightly pre-load- ed against the underside of the flat-way. Tighten the jam nuts when finished.
