Gibs

Gibs are wedge-shaped pieces of metal that fill the gap between the sliding surfaces of the machine. By adjusting the position of the gib in its gap, you can remove any play that might exist between the adjacent components. The gibs are pre-adjusted at the factory but due to storage, break-in, and usage, may require adjustment. If movement seems too tight at first, make sure that all the rust preventative that was shipped on the machine is removed from the ways. Lubricate the ways with oil, and work the table back-and-forth several times until the movement is easier.

To adjust the table gibs:

1.DISCONNECT MILL/DRILL FROM POWER!

2.Loosen the table travel locks (Figure 54).

3.Loosen or tighten the front and rear gib screws (Figure 54) in an alternating manner to adjust the cross travel gib.

The table should slide smoothly in the cross direction with no play or looseness. Do not overtighten the gibs or premature slide and gib wear will occur.

4.Lubricate the cross way and gib.

5. Repeat the process for the longitudinal way gib using the gib adjustment screws on the left and right sides of the table base.
