Adjusting Gibs
Figure 33. Gib adjustment.
The function of the gibs is to take out play in the
table, and cross slide, and column without causing
the slides to bind. The gibs are pre-adjusted at the
factory and should not need further adjustment
until many hours of machine use. If the movement
seems too tight at first, make sure the locks are
fully released. Next, make sure the bedways are
thoroughly cleaned of rust preventative and lubri-
cated with oil.
Tools Needed: Qty
Wrench 10mm ................................................... 1
Hex Wrench 3mm .............................................. 1
Each gib has multiple lock nuts and set screws
that need to be adjusted. Make your adjustments
equally and in small increments.
To adjust the gibs: (see Figure 33)
1. DISCONNECT MILL FROM POWER!
2. Loosen the lock nuts.
3. Move the table and slightly tighten each
set screw. When properly adjusted, the gib
should offer slight resistance without bind-
ing.
4. Tighten the lock nuts.
