there are a number of ways to check and align
the cutting tool to the spindle centerline. if nec-
essary, you can raise the cutting tool by placing
steel shims underneath it. the shims should be
as long and as wide as the cutting tool to properly
support it.
below are two common methods:
•
Move the tailstock center over the cross slide
and use a fine ruler to measure the distance
from the surface of the cross slide to the tip
of the center. Adjust the cutting tool height so
it is the same distance above the cross slide
as the tailstock center.
•
Align the tip of the cutting tool with a tailstock
center, as described in the following pro-
cedure. For this to work, the tailstock must
be aligned to the spindle centerline (refer to
Aligning Tailstock To Spindle centerline
on page 37 for detailed instructions).
