ALIGNMENT AND CALIBRATION
TABLE ALIGNMENT
Checking Table Alignment
To check the table alignment, perform the following procedure:
1.
Using a measuring tape, and referring to Figure 4-1, check the following:
•
Distance from the edge of the table to the back of both T-rails (measurement “A”).
•
Distance between the T-rails (front and rear).
•
Gap from the edge of the table bracket (left side) to the rail.
2.
Record all the measurements.
3.
Facing the front of the QDR 4500, gently push the foot end (left side) of the table. The
table should move away from, then back to its original position.
4.
Check measurement “A” and the bracket to guide rail gap again, and compare them to
their original values.
5.
If all the measurements are within specs, the table is properly aligned. If the
measurements are not within specs, go to the Aligning Table section.
Aligning Table
After you have taken the measurements in the Checking Table Alignment section, use the
procedures below to align the table. Note that if both measurement “A” and the bracket to guide
rail gap are out of specification, you should recheck the measurements after performing the first
adjustment.
Table Edge to T-Rail (“A” Dimension) Adjustment
To change the “A” dimension, do the following:
1.
Remove the upper and lower covers from the right pedestal.
2.
Loosen the four bolts fastening the top of the pedestal and the four bolts fastening the
bottom of the pedestal (see Figure 4-2).
3.
Adjust the table so the “A” measurements are within specifications.
4.
Tighten the bolts and check the table alignment again.
If the alignment is within specifications, replace the pedestal covers. If you still note a change in
the “A” measurement, continue with the following steps.
