Aligning Table with
Mill X-Axis
The rotary table should be aligned with the X-axis
of the mill. The rotary table can be mounted to the
mill table using the supplied T-slot bolt assemblies
or step clamps.
To align rotary table with mill X-axis:
1.
Place rotary table with chuck on mill table.
2.
Position a precision square across front
edge of mill table and adjust rotary table flat
against square, as shown in Figure 19, then
clamp rotary table in place.

to indicate one side of face or back of a
workpiece mounted in chuck jaws.
4. Move mill table in and out to indicate across
full width of rotary table.
5. If necessary, loosen clamps and lightly tap
rotary table into position so indicator reads
zero deviation across full width of rotary
table, then reclamp it.
