Gibs are tapered lengths of metal that are 
sandwiched between two moving surfaces. Gibs 
control the gap between these surfaces and how 
they slide past one another. Correctly adjusting 
the gibs is critical to producing good milling 
results.

Tight gibs make table movement more 
accurate but stiff. Loose gibs make moving the 
table sloppy but easier to do. The goal of gib 
adjustment is to remove unnecessary sloppiness 
without causing the ways to bind.

Gibs are adjusted with a screw on each end of 
the gib, that move the tapered gib back-and-
forth to increase or decrease the friction pressure 
between the sliding surfaces. The process of 
properly adjusting the gibs requires trial-and-
error and patience.

DISCONNECT MILL FROM POWER BEFORE 
ADJUSTING THE GIBS!

Make sure all table and knee locks are loose. 
Then, loosen one gib adjustment screw and 
tighten the other the same amount to move the 
gib. Use the ball handles/crank to move the table/
knee until you feel a slight drag in that path of 
movement.

Refer to Figures 61–63 to identify the locations 
of the table, saddle, and knee gibs, and one of the 
two adjustment screws for each.

 It will be necessary to remove small parts, 

such as way wipers and covers, to access the gib 
adjustment screws.
