Horizontal Installation Alignment
Two methods are described below for aligning the mill spindle and rotary table centerlines when the rotary table is mounted horizontally.
To use a test indicator to align the rotary table:
1.DISCONNECT MILL FROM POWER!
2.Mount the test indicator to the mill spindle offset from the spindle centerline by the radius of the rotary table spindle bore, then position the tip on the inside vertical surface of the rotary table spindle bore (see Figure 5 for an example).
Figure 5. Example of using a test indicator to align a rotary table.
3.Turn the mill spindle by hand so that the test indicator is aligned to the
Note: For best results, turn the mill spindle in only one direction.
4.Slowly move the mill table until the test indicator reads zero deviation.
5.Rotate the mill spindle and test indicator 90°, then repeat Step 4.
6.Repeat Step 5 until the test indicator reads zero deviation in all four directions.
Tip: Use a mirror to read the indicator when it is facing away from you.
To use an edge finder to align the rotary table:
1.Mount an edge finder into the mill spindle, then position it roughly in the center of the rotary table spindle bore and below the rotary table surface.
2.Set the mill spindle speed to
3.Slowly move the mill table along the
Note: When recording the mill table position, take into account the backlash that is usually present in the leadscrew.
4.Slowly move the mill table in the opposite direction until you again find the edge of the spindle bore, then note the table position on the handwheel dial.
5.Calculate the difference of the mill table positions from Steps
6.Move the mill table 1⁄2 the amount calculated in Step 5 along the
