The unpainted surfaces are coated
at the factory with a heavy-duty
rust preventative that prevents
corrosion during shipment and
storage.The benefit of this rust
preventative is that it works very
well. The downside is that it can
be time-consuming to thoroughly
remove.
Be patient and do a careful job when
cleaning and removing the rust
preventative. The time you spend
doing this will reward you with
smooth-sliding parts and a better
appreciation for the proper care of
the unpainted surfaces.
Although there are many ways
to successfully remove the rust
preventative, we have cleaned
thousands of machines and found
the following process to be the best
balance between efficiency and
minimized exposure to toxic fumes
or chemicals.
Before cleaning, gather the
following:
•Disposablerags
•Cleaner/degreaser (certain
citrus-based degreasers work
extremely well and they have
non-toxic fumes)
•Safetyglasses&disposable
gloves
Note: Automotive degreasers,
mineral spirits,orWD•40canbe
used to remove rust preventative.
Before using these products, though,
test them on an inconspicuous area
of a painted area to make sure they
will not damage it.
Basic steps for removing rust
preventative:
1. Put on safety glasses and
disposable gloves.
2. Coatallsurfacesthathave
rust preventative with a liberal
amount of your cleaner or
degreaser and let them soak for
a few minutes.
3. Wipe off the surfaces. If your
cleaner or degreaser is effective,
the rust preventative will wipe
off easily.
Note: To clean off thick coats of rust
preventative on flat surfaces,
such as beds or tables, use
aPLASTICpaintscraperto
scrape off the majority of the
coating before wiping it off with
yourrag.(Donotuseametal
scraper or it may scratch the
surface.)
4. Repeat Steps 2–3 as necessary
until clean, then coat all
unpainted surfaces with a
quality metal protectant or light
oil to prevent rust.
Gasoline and petroleum
products have low flash points
and can explode or cause fire if
used for cleaning. Avoid using
these products to remove rust
preventative.
Many cleaning solvents are toxic
if inhaled. Minimize your risk by
only using these products in a
well ventilated area.

PREPARATION
Installation
Before installing the rotary
table, make sure that the spindle
centerline is properly aligned or
"trammed" with the mill table. Also,
remove any burrs or scratches from
the mating surfaces of the rotary
and mill table by "stoning" them,
then thoroughly wipe them clean
and dry (refer to the Surface Care
section on Page 16 for detailed
instructions).
Horizontal Installation
The horizontal base has slots (see
Figure 3) that accept keys for
quick alignment with the mill table.
Because of the many variations in
mill table T-slots, these keys are not
provided with the rotary table. If
you choose to use keys for alignment
when installing the rotary table
horizontally, you will have to
machine them to fit the rotary table
and your mill table.

To mount the rotary table
horizontally:
1. DISCONNECT MILL FROM
POWER!
2. Position the rotary table
horizontally on the mill table so
that the mounting slots shown
in Figure 3 are aligned with the
mill table center T-slot.
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.
3. Attach the rotary table to the
mill table with the clamping
hardware, but leave the
fasteners loose for now.
4. Placethemachinist'ssquare

Page 10.
Aligning to Spindle
Centerline
Whether the rotary table is mounted
horizontally or vertically, you must
align the rotary table centerline
to the mill spindle centerline to
achieve quality results. Also, the
spindle centerline must first be
properly aligned to mill table in both
the X- and Y- axis (this procedure
is generally called "tramming the
spindle").
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.
-8-
There are many methods for
aligning the centerlines, and it
is up to the machinist and their
capabilities to decide which
approach is best.
PREPARATION
Horizontal Installation
Alignment
Two methods are described below
for aligning the mill spindle and
rotary table centerlines when the
rotary table is mounted horizontally.
To use a test indicator to align the
rotary table:
1. DISCONNECT MILL FROM
POWER!
2. Mount the test indicator to the
mill spindle offset from the
spindle centerline by the radius
of the rotary table spindle bore,
then position the tip on the
inside vertical surface of the
rotary table spindle bore (see
Figure 5 for an example).
SB1363- 64 /SB1367-68Mfg. Since 10/09
6. Repeat Step 5 until the test
indicator reads zero deviation in
all four directions.
Tip: Use a mirror to read the
indicator when it is facing away
from you.
To use an edge finder to align the
rotary table:
1. Mount an edge finder into the
mill spindle, then position it
roughly in the center of the
rotary table spindle bore and
below the rotary table surface.
2. Set the mill spindle speed to
800–1000 RPM, then turn the
mill ON.
3. Slowly move the mill table along
the X-axis in one direction until
the edge finder meets the edge
of the rotary table spindle bore,
then note the position of the
table on the handwheel dial.
Figure 5. Example of using a test
indicator to align a rotary table.
3. Turn the mill spindle by hand so
that the test indicator is aligned
to the X-axis of the mill table.
Note: For best results, turn the mill
spindle in only one direction.
4. Slowly move the mill table until
the test indicator reads zero
deviation.
5. Rotate the mill spindle and
test indicator 90°, then repeat
Step 4.
Note: When recording the mill table
position, take into account the
backlash that is usually present
in the leadscrew.
4. Slowly move the mill table in
the opposite direction until
you again find the edge of the
spindle bore, then note the table
position on the handwheel dial.
5. Calculate the difference of
the mill table positions from
Steps 3–4.
6. Move the mill table
1
⁄2 the
amount calculated in Step 5
along the X-axis. Be sure to take
into account any backlash.

4. Repeat Step 3 until the entire
rotary table surface is correctly
aligned with the mill spindle.
To center the rotary table with the
mill spindle centerline:
1. DISCONNECT MILL FROM
POWER!
2. Fully seat a lathe center into the
rotary table spindle.
Note: Any center runout will have to
be determined and accounted for
in the following steps.
3. Use an edge finder mounted in
the mill spindle to find the edge
of the center, as illustrated in
Figure 7.
To verify the front-to-back alignment
of the rotary table to the mill
spindle:
1. DISCONNECT MILL FROM
POWER!
2. Mount a test indicator to the
mill spindle and position the
indicator tip on one end of the
rotary table face.
3. Move the mill table along the
Y-axis and note any deviations
in the test indicator.
— If a deviation is found, loosen
the rotary table mounting
fasteners, tap the rotary
table into the proper position,
then re-tighten the mounting
fasteners.

Figure 7. Using an edge finder and center
to align the rotary table (top view).
4. Measure the diameter of the
center where the edge finder
makes contact, divide this
number in half, then add half of
the edge finder diameter. The
result is the amount you need
to move the mill table along the
Y-axis to center the rotary table
with the mill spindle centerline.
Note: Be sure to take into account
any backlash and any rounout
of the center when moving the
table.

OPERATION
Mfg. Since 10/09
Tip: When using the rotary table
to machine several locations or
with a complicated pattern, make a
drawing with measurement details
to help visualize the operation. This
will reduce the risk of making errors
during the operation.
To make five evenly spaced holes:
1. Use the handwheel to rotate the
rotary table to the 0° mark on
the rotation scale, then tighten
both table locks.
2. Drill the first hole.
3. Unlock the table, then turn
the handwheel 18 full turns.
This will rotate the rotary table
to 72°, as displayed on the
rotational scale.
Important: Be careful not to pass the
handwheel scale 0° mark on the
last turn. If you go past the 0°
mark, reverse the handwheel
one full turn, then try again.
This will eliminate any backlash
error that occurs when reversing
the handwheel direction.
4. Lock the table in place and drill
the hole.
5. Repeat Steps 3–4 to produce
the third hole at 144°, the fourth
hole at 216°, and the fifth hole
at 288°.
Two Circular Slots
In this example, you will cut two 92°
circular slots in a round workpiece,
as illustrated in Figure 13.
Figure 13. Layout for creating two
To make two circular slots:
1. Use the handwheel to rotate
the rotary table to the 0° mark

gear and shaft (Page 17).
Cleaning & Protecting
It is essential that the rotary table
be cleaned after every use. DO
NOT use compressed air to clean
your rotary table. Chips or debris
may become lodged between the
moving parts, reducing the life and
accuracy of the tool. Instead, use a
stiff-bristled brush to remove the
chips and swarf, then wipe down
the machined surfaces with a clean
shop rag before applying a thin
coat of light machine oil to prevent
corrosion.
Surface Care
Nicks, dings, and scratches on the
machined surfaces of the rotary
table can have an adverse effect
on accuracy and may damage the
workpiece or mill table.
Prior to use, dress or "stone" these
machined surfaces with a fine
sharpening stone. A few strokes
of the stone on the rotary table
surface, the machined base and
back, and the mill table will help
to ensure longevity and accuracy.
Make sure to thoroughly wipe these
surfaces clean to remove any dust
generated from the process, then
apply a thin coat of light machine oil
to prevent corrosion.

Tip: After stoning and wiping down
the surfaces, run your fingers lightly
across the surfaces to detect any
irregularities.
MAINTENANCE
Lubrication
The recommended schedule
on the previous page for the
lubrication tasks is based on
light-to-medium usage. Keeping
in mind that lubrication helps to
protect the value and operation
of the rotary table, these
lubrication tasks may need to be
performed more frequently than
recommended, depending on
usage.
Failure to follow reasonable
lubrication practices as
instructed in this manual could
lead to premature failure of the
rotary table components and will
void the warranty.
Ball Oilers
There are two ball oilers (see
Figure 14) that must be lubricated
before daily use, or more often with
heavy use.
SB1363- 64 /SB1367-68Mfg. Since 10/09
Important: Use an oil can or gun
that has a plastic or rubber tip.
Metal tips can damage the ball and
spring inside the oilers.
Clean away debris and grime from
around the ball oilers, then depress
the ball with the oil can tip to add
oil until it is seen exiting between
the parts. Clean away any excess
lubricant, then rotate the table at
least one full revolution to evenly
disperse the lubricant.
Worm Gear & Shaft
To gain access to the worm gear and
shaft for cleaning and lubrication,
you need to remove the table from
the cast iron housing.

2. Use the backlash adjustment
ring to disengage the gears from
the handwheel so that the table
rotates freely by hand.
3. Turn the rotary table upside
down on a protective surface.
4. Loosen the cap screw that
secures the spindle lock collar,
then unthread and remove the
collar (see Figure 16).

5. Lift the edge of the cast iron
housing with one hand, and tap
the back end of the spindle with
the dead blow hammer until the
table assembly breaks free from
the housing.
7. Use the stiff-bristled brush,
shop rags, and mineral spirits
to clean grime and debris from
inside the housing cavity, the
worm shaft, and the worm gear.
8. When these parts are dry, apply
a medium coat of multi-purpose
gear grease to the teeth of the
worm shaft and gear.
9. Use a clean shop rag and
mineral spirits to wipe clean
the mating surfaces of the
housing and table, then apply
a thin coat of light machine
oil to the housing oil grooves
and surrounding surface (see
Figure 17).
10. Re-install the table, the spindle
lock collar, and the table lock
assemblies, then perform the
Spindle Preload procedure as
instructed on the next page.
6. Remove the table from the
housing, as shown in Figure 17.

Spindle Preload
Setting the spindle preload on the
rotary table affects the accuracy and
ease of use during operation.
Keep in mind, that too much preload
will make table rotation difficult
and will cause pre-mature wear of
the gears and mating surfaces of
the table. Conversely, not enough
preload may result in reduced
accuracy. Use your best judgment
when setting the spindle preload on
the rotary table.
Tool Needed Qty
Hex Wrench 3mm. . . . . . . . . . . . . . 1
To set the rotary table spindle
preload:
1. Make sure the table locks are
loose.
2. Use the backlash adjustment
ring to disengage the worm
shaft from the worm gear so
that the table can be freely
rotated by hand and not the
handwheel.
4. From the back of the rotary
table, loosen the spindle lock
collar cap screw (see Figure 16
on the previous page).
5. Loosen the lock collar at least
two full turns to remove any
preload.
6. Rotate the table by hand as you
re-tighten the lock collar. When
it becomes difficult to turn the
table, back off the lock collar
slightly until the table rotates
freely again, then, while keeping
the lock collar from rotating, retighten the lock collar cap screw.
7. Use the backlash adjustment
ring to re-engage the worm
shaft and gear, then test the
table rotation by using the
handwheel.
— If you are not satisfied with
the table rotation, repeat
this procedure to re-adjust
the preload until you are
satisfied with the results.
3. Position the table in a vertical
position so that both the front
and the back are accessible.
