Gibs and Backlash

During the life of your mill drill, you may have to adjust the gibs and the handwheels to remove any lash or looseness that is a result of normal wear. Do not overtighten the gibs or half-nuts, or premature wear will occur.

2.Loosen the lock nuts (see Figure 32).

Figure 32. Gib adjustment.

3.When properly adjusted, the table should move with slight resistance as felt in the handwheel. Each gib has multiple lock nuts and set screws that must also be adjusted. Make your adjustments equally and in small increments.

4.Tighten the lock nuts.

5.Locate the X-axis lead screw half-nut (see Figure 33), and adjust both cap screws until the handwheel has approximately 0.003" backlash as shown by the dial.

6.Repeat Step 5 on the Y-axis leadscrew half- nut and lubricate the lead screws and gibs.
