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:
• Disposablerags
• Cleaner/degreaser (certain
citrus-based degreasers work extremely well and they have non-toxic fumes)
• Safetyglasses&disposable
gloves
Note: Automotive degreasers, mineral spirits,orWD•40canbe 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. Coatallsurfacesthathave
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
aPLASTICpaintscraperto
scrape off the majority of the coating before wiping it off with
yourrag.(Donotuseametal
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. Placethemachinist'ssquare
along the front edge of the mill table and the machined foot of the rotary table, square the rotary table to the mill table, then fully tighten the clamping fasteners.
Figure 3. Locations of the horizontal
base key slots and mounting slots
(Model SB1363 shown).
You MUST properly secure the rotary table to the mill table to prevent unexpected movement of the rotary table and workpiece during operation, which could result in personal injury or workpiece damage.

To mount the rotary table vertically:
1. DISCONNECT MILL FROM
POWER!
2. Insert the clamping hardware
into the outer mill table T-slots.
3. Place the rotary table on the
mill table so that you can use the clamping hardware to secure it in the next step.
4. Placethemachinist'ssquare
along the front of the mill table and the machined side of the rotary table foot, square the rotary table to the mill table, then fully tighten the clamping hardware.
5. Perform the Vertical
Installation Alignment
procedure as instructed on 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.

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

Vertical Installation Alignment
In these procedures, you will verify the rotary table alignment with the mill spindle from front to back and to its centerline.
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 on the rotational scale, then tighten the table locks.
2. Move the mill table to the left

internal cavity of the rotary table, then lubricate the worm 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.
-16-
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.
