Vertical Installation

Alignment

In these procedures, you will verify the rotary table alignment with the mill spindle from front to back and to its centerline.

To verify the front-to-back alignment of the rotary table to the mill spindle:

1.DISCONNECT MILL FROM POWER!

2.Mount a test indicator to the mill spindle and position the indicator tip on one end of the rotary table face.

3.Move the mill table along the Y-axis and note any deviations in the test indicator.

—If a deviation is found, loosen the rotary table mounting fasteners, tap the rotary table into the proper position, then re-tighten the mounting fasteners.

4.Repeat Step 3 until the entire rotary table surface is correctly aligned with the mill spindle.

To center the rotary table with the mill spindle centerline:

1.DISCONNECT MILL FROM POWER!

2.Fully seat a lathe center into the rotary table spindle.

Note: Any center runout will have to be determined and accounted for in the following steps.

3.Use an edge finder mounted in the mill spindle to find the edge of the center, as illustrated in Figure 7.

4.Measure the diameter of the center where the edge finder makes contact, divide this number in half, then add half of the edge finder diameter. The result is the amount you need to move the mill table along the Y-axis to center the rotary table with the mill spindle centerline.

Note: Be sure to take into account any backlash and any rounout of the center when moving the table.
