Alignment
Aligning the center of the rotary table to the spin-
dle is essential for achieving quality results.
There are many ways to align the Model G1049
to a vertical mill spindle. It is up to the machinist
and his capabilities to decide which approach is
best.
Here are a couple of ways to align the spindle
accurately to the center of the rotary table:
Using a test indicator, (see Models G9610,
1.
G9611 & G9612 in the current Grizzly cata-
log) indicate the inside or the outside of the
rotary table. Position the spindle over center
of the rotary table and touch all four sides
(inside or outside) until all sides read "0" on
the indicator (remember to rotate the spindle
and not the rotary table). Using this proce-
dure of indicating, no measuring tools are
needed.

Use an edge finder, like the Model H2939, to
2.
locate the center of the rotary table by con-
tacting two outside edges (Figure 2) and
then moving the mill table half of the rotary
table diameter in both directions. Note—
Make sure to account for radius of the edge
finder and use a precision measuring instru-
ment when determining the diameter of the
rotary table.
