Installation
Before installing your rotary table, make sure that
your mill table and spindle are properly aligned
as instructed in your mill's owner manual. Also,
remove any burrs or scratches from the mating
surfaces of the mill and rotary tables by “stoning”
them, then thoroughly wipe them clean and dry
(refer to the
Surface Care subsection on page 18
for detailed instructions).
Horizontal position
1. disConneCt Mill FroM poWer!
2. position the rotary table horizontally on the
mill table so that the center mounting slot is
aligned with the center t-slot of the table.
3. insert the M12-1.75 x 80 t-bolt into the mill
table t-slot and slide it into the rotary table
mounting slot, then install the flat washer and
hex nut, but do not tighten them for now.
4. use the horizontal clamp, M12-1.75 x 60
t-bolt, flat washer, and hex nut to hold the
opposite end of the rotary table, but do not
tighten it for now.
5. place a precision square along the front edge
of the mill table and the foot of the rotary
table, square the rotary table to the mill table,
then fully tighten the hex nuts.
6. perform the Alignment procedure as instruct-
ed on page 9.
You MuST properly secure the rotary table
to the mill table to prevent unexpected
movement during operation, which could
result in personal injury or damage to the
workpiece.
Vertical position
it will be necessary to compare the center-to-cen-
ter distance between the t-slots of your mill table
to the vertical mounting holes of the rotary table.
if the mounting holes do not intersect the mill
table t-slots with sufficient space for the t-bolts,
use step blocks and clamps in place of one of the
t-bolts.
the alignment keys on the foot of the rotary table
measure approximately 0.630" (16mm) and are
used to align the rotary table. if they are wider
than the mill table t-slots, machine a step into
them so that they will fit properly. otherwise, they
can be removed to allow manual alignment.
To install the rotary table in the vertical posi-
tion:
1. disConneCt Mill FroM poWer!
2. insert the two M12-1.75 x 60 t-bolts in the
outer slots of the mill table.
3. Align the vertical mounting holes of the rotary
table with the t-bolts, then place the rotary
table onto the mill table with the alignment
keys, if used, into the table's center slot.
— if the alignment keys are not used, place a
precision square along the mill table front
edge and the machined side of the rotary
table foot, then square the rotary table to
the mill table.
4. install the flat washers and hex nuts onto the
t-bolts to secure the rotary table in place.
5. perform the Alignment procedure as instruct-
ed on page 9.
NOTICE
Make sure the rotary table handwheel is free
of obstructions. Depending on your setup,
the rotary table may need to be blocked up
or mounted so the handle is hanging over
the edge of the mill table. After installation,
carefully check for any possible obstruc-
tions that may interfere with the rotary table
or its handwheel.
