Figure 37 – SMX 3500 - Table Gib Screw
5.2.1.2
Gib Adjustment, X-Axis – 4000 & 5000
The X-axis has 2 gibs for the table because of the length of the saddle. Each gib is adjusted from
each end of the table. There are not 2 adjustment screws at either end of the gib like the Y-axis and
Z-axis.
1. Clean all swarf, dirt and excess oil from the table.
2. Remove the table trays.
3. Move the table to the left and mount the indicator at Point D and move the table back and
forth. Note the amount of movement of the dial indicator. Adjust gib until the movement is
between 0.013 - 0.03 mm.
4. Move the table to the right and mount the indicator at Point A and move the table back and
forth. Note the amount of movement of the dial indicator. Adjust gib until the movement is
between 0.013 - 0.03 mm.
To adjust the gib for excess clearance: Loosen the nut closest to the table and
tighten the nut furthest from the table. Once the clearance has been taken up tighten
each nut against the gib bracket. Do this for each end of the table.
To adjust the gib for too small of a clearance: Loosen the nut furthest from the
table and tighten the inside nut up against the bracket to pull the gib away from the
machine. Once the clearance has been taken up tighten each nut against the gib bracket.
Do this for each end of the table.
5. Replace the table trays. See Figure 38.
