Step 5 : Install the bearing housing #8 square with the ball screw axis. Please make sure bearing
housing #8 is securely positioned with using part #9.
Step 6 : Now tighten the first nut, part #23 to put the bearings against the housing. Loosen the
nut and retighten again to position the bearing properly. Install the second jam nut, part #23, to
secure the first nut also.
Step 7 : Rotate the screw manually to ensure there is no jerky motion of the screw or the
bearings are not creating any stop and go motion or are completely jammed.
Adjustment of Gibs on the X & Y Axis Slides
The X & Y axis slides have straight gibs. If the slide motion proves out to be sloppy or uneven,
adjust the gibs evenly using the set screw provided on the front and side of the casting.
Step 1 : Make sure that the slide is properly lubricated before you start adjusting the screws.
Step 2 : Loosen the gib hex head bolts.
Step 3 : Tighten the gib set screws all the way so there is no table movement.
Step 4 : Loosen all set screws one at a time a quarter of a turn and check the motion for “fish
tailing” and uneven motions to and from.
Step 5 : Adjust all the set screws until the “fish tailing” movement is eliminated.
Step 6 : Tighten the gib hex head bolts. Do NOT exceed 100 in-lb torque.
The tighter the gib the more accurate it will be in motion but the required to move the slide
may also go up due to the increased sliding friction. Removing and cleaning the gibs before
installation is also helpful.
With the gibs properly adjusted and the slides lubricated, the torque required to move the slide
slowly, should not exceed 15
– 20% of the maximum motor torque available.
