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).

3.  Turn the mill spindle by hand so 

that the test indicator is aligned 
to the X-axis of the mill table.

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 

800–1000 RPM, then turn the 
mill ON.

3.  Slowly move the mill table along 

the X-axis in one direction until 
the edge finder meets the edge 
of the rotary table spindle bore, 
then note the position of the 
table on the handwheel dial.

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 3–4.

6.  Move the mill table

 the 

amount calculated in Step 5 
along the X-axis. Be sure to take 
into account any backlash.
