 A precision-ground plate can be substituted 

for the parallel blocks. Keep in mind that the 
farther the indicator point can be placed from the 
spindle axis, the more accurate the alignment 
measurements will be.

  DISCONNECT MILL FROM POWER!

  Prepare the mill by performing the following 

tasks:

s

burrs, then clean off all debris. Verify the 
table is clean by running your hand over 
the top of it.

s

operation you intend to perform after the 
tramming—preferably centered to the 
saddle.

s

locks that should be tight during the 
intended milling operation.

  Place the parallel block underneath the 

spindle.

Indicator Holder

Parallel Block

  Install the indicator holder into the spindle 

or onto the quill, then mount the indicator 
onto it so that the point is as parallel to 
the block as possible (see the illustration in 
Figure 26 for an example).

  To measure spindle alignment along the 

X-axis, place the parallel block directly under 
the spindle and indicator across the length of 
the table, as illustrated in Figure 27.

 If you must re-position the quill or the 

knee to accommodate the above step, then 
review the tasks in Step 2 to make sure the 
mill is properly prepared for the tramming 
operation.
