Note: Generally, the goal in the next steps is to get the difference of the indicator readings between the end of the parallel bar down to 0.0005". However, the acceptable variance will depend on the requirements for your operation.

6.Rotate the spindle by hand so that the indicator point rests on one end of the parallel block, as illustrated in Figure 29, then zero the dial.

7.Rotate the spindle so that the indicator point rests in the same manner on the other end of the block, then read the dial.

—If the indicator dial still reads zero or is within the acceptable variance, continue on with Step 8.

—If the indicator dial has moved from zero beyond the acceptable variance, you will need to compensate for that amount by rotating the head left or right. Repeat Steps 5–6until you are satisfied with the spindle axis alignment along the table X-axis.

Note: Keep one of the rotation lock bolts snug so that the head does not move loosely while you adjust it small amounts.

8.Re-tighten the rotation lock bolts.

Note: It is a good idea to repeat Steps 5-6again in case the head moved slightly during the process of re-tightening the lock bolts.

9.Place the parallel block directly under the spindle and across the width of the table, as illustrated in Figure 30.

10.Rotate the spindle so that the indicator point rests on the parallel bar, as illustrated in Figure 30, then zero the dial.

11.Rotate the spindle so that the indicator point rests on the other end of the bar in the same manner, then read the dial.

—If the indicator dial still reads zero or is within the acceptable variance, the spindle is precisely perpendicular to the table in both the X- and Y-axes and the tramming procedure is complete.

—If the indicator dial has moved from zero beyond the acceptable variance, you will need to compensate for that amount by tilting the head forward or back. Repeat Steps 9–10until you are satisfied with the spindle axis alignment along the table Y-axis.

Note: Keep one of the tilt lock bolts snug so that the head does not move loosely while you adjust it small amounts.

12.Re-tighten the tilt lock bolts.

Note: It is a good idea to repeat Steps 9-10again in case the head moved slightly during the process of re-tightening the lock bolts.
