level. When the end of travel is reached, the leveling screws on the end of the table base can be
slightly adjusted.
7. Return the table to the center of travel. Verify that earth level still applies to the table at that posi-
tion. If it does not, it must be attained again before continuing.
Only the leveling screws that
have been previously adjusted should be used. Do not alter the position of the four pri-
mary leveling screws at this time.
8. Move the table in the same increments as before but in the direction away from zero. Repeat the
very slight adjustment procedure, beginning to make a correction in the table, level to earth.
9. Move the table back to the center of travel and verify that the primary earth zero has not been af-
fected. If earth zero does not exist at the center of travel, make the correction now.
The load of the table base assembly is now being shared over all of the leveling screws. The table at the cen-
ter of travel is at earth zero, and the column base is at earth zero.
Fine Leveling of the Table Base
Using the same process as loading the leveling screws in the previous steps, move the table over to line up
the levels with the leveling screws and begin to make very moderate adjustments toward earth zero. Continue
the process to the end of travel as before, then return to the center of travel and verify earth zero there. Move
from the center of travel the other direction and repeat the procedure until the table is at earth zero over the
entire travel of the X-axis.
Verify that the Y-axis has not been affected by the leveling procedure of the X-axis. If it has, use the steps
described previously to make the necessary correction and then verify that the X-axis is still correct.
Do not try to hurry this process. This is a careful, repetitive, process that relies on modest adjustments for
each step along the way. If too large an adjustment is attempted, the geometry will fail and it may not be pos-
sible to determine the corrective action and the bases may have to be disconnected to rectify the situation.
When
fine leveling is completed, tighten the jam nuts on the leveling screws.

The sweep of the table should be little more than a verification of the leveling process. Using the special tool
for mounting the indicator, first verify that the table is within specification as the Y-axis (VS) / Z-axis (HS) is
moved. Then, for several Y-axis (VS) / Z-axis (HS) positions where the indicator is on the table surface, run
the X-axis from end to end and verify that it is also within specification.

The final step of the leveling and squaring process is to verify the overall machine geometry with respect to
the individual geometric inspection report of the machine. Every point of inspection must be verified to be
within the tolerances specified for the machine.

1. Seal the shipping bracket bolt holes to prevent oil leaks.
2. Replace all sheet metal removed paying particular attention to sealing any component mating
surface potentially exposed to coolant flow.
3. Install the table gutter fence.
4. Install and verify operation of the tool changer (see the section on tool changer installation and
alignment for the specific toolchanger).
5. Verify all machine functions.
