Operating all machinery and machining equipment can be dangerous or relatively safe depending
on how it is installed and maintained, and the operator's experience, common sense, risk awareness,
working conditions, and use of personal protective equipment (safety glasses, respirators, etc.).

The owner of this machinery or equipment is ultimately responsible for its safe use. This
responsibility includes proper installation in a safe environment, personnel training and usage
authorization, regular inspection and maintenance, manual availability and comprehension,
application of safety devices, integrity of cutting tools or accessories, and the usage of approved
personal protective equipment by all operators and bystanders.

The manufacturer of this machinery or equipment will not be held liable for injury or property
damage from negligence, improper training, machine modifications, or misuse. Failure to read,
understand, and follow the manual and safety labels may result in serious personal injury, including
amputation, broken bones, electrocution, or death.

The signals used in this manual to identify hazard levels are as follows:

Moderate injury or fire
MAY occur.

Machine or property
damage may occur.

Basic Machine Safety

equipment presents serious injury hazards
to untrained users. To reduce the risk of
injury, anyone who uses THIS item MUST
read and understand this entire manual
before starting.

Personal Protective Equipment:

servicing this item may expose the user
to flying debris, dust, smoke, dangerous
chemicals, or loud noises. These hazards
can result in eye injury, blindness, long­term respiratory damage, poisoning,
cancer, reproductive harm or hearing loss.
Reduce your risks from these hazards
by wearing approved eye protection,
respirator, gloves, or hearing protection.

Operating or

users can seriously injure themselves
or bystanders. Only allow trained and
properly supervised personnel to operate
this item. Make sure safe operation
instructions are clearly understood. If
electrically powered, use padlocks and
master switches, and remove start switch
keys to prevent unauthorized use or
accidental starting.

Guards/Covers:

moving parts during operation may cause
severe entanglement, impact, cutting,
or crushing injuries. Reduce this risk by
keeping any included guards/covers/doors
installed, fully functional, and positioned
for maximum protection.

Chuck Keys or Adjusting Tools:

Tools used to

our Technical Support for assistance.

SAFETY

jewelry or long hair may get caught in
moving parts, causing entanglement,
amputation, crushing, or strangulation.
Reduce this risk by removing/securing
these items so they cannot contact moving
parts.

Mental Alertness: Operating this item with

reduced mental alertness increases the
risk of accidental injury. Do not let a
temporary influence or distraction lead to a
permanent disability! Never operate when
under the influence of drugs/alcohol, when
tired, or otherwise distracted.

Safe Environment:

powered equipment in a wet environment
may result in electrocution; operating near
highly flammable materials may result in a
fire or explosion. Only operate this item in
a dry location that is free from flammable
materials.

Electrical Connection: With electically powered

equipment, improper connections to the
power source may result in electrocution
or fire. Always adhere to all electrical
requirements and applicable codes when
connecting to the power source. Have all
work inspected by a qualified electrician to
minimize risk.

Disconnect Power: Adjusting or servicing

electrically powered equipment while it
is connected to the power source greatly
increases the risk of injury from accidental
startup. Always disconnect power
BEFORE any service or adjustments,
including changing blades or other tooling.

Operating electrically

adjust spindles, chucks, or any moving/
rotating parts will become dangerous
projectiles if left in place when the machine
is started. Reduce this risk by developing
the habit of always removing these tools
immediately after using them.

Work Area:

the risks of accidental injury. Only operate
this item in a clean, non-glaring, and well­lighted work area.

Properly Functioning Equipment:

maintained, damaged, or malfunctioning
equipment has higher risks of causing
serious personal injury compared to
those that are properly maintained.
To reduce this risk, always maintain
this item to the highest standards and
promptly repair/service a damaged or
malfunctioning component. Always follow
the maintenance instructions included in
this documentation.

Unattended Operation:

equipment that is left unattended while
running cannot be controlled and is
dangerous to bystanders. Always turn the
power OFF before walking away.

Health Hazards: Certain cutting fluids and

lubricants, or dust/smoke created when
cutting, may contain chemicals known to
the State of California to cause cancer,
respiratory problems, birth defects,
or other reproductive harm. Minimize
exposure to these chemicals by wearing
approved personal protective equipment
and operating in a well ventilated area.

Clutter and dark shadows increase

Secure Workpiece/Tooling:

cutting tools, or rotating spindles can
become dangerous projectiles if not
secured or if they hit another object during
operation. Reduce the risk of this hazard
by verifying that all fastening devices are
properly secured and items attached to

SAFETY

Additional Drill Press Safety

For Machines Mfd. Since 1/21

Flying chips
created by drilling can cause eye injuries
or blindness. Always wear a face shield
in addition to safety glasses. Always keep
hands and fingers away from drill bit/cutting
tool. Avoid awkward hand positions, where
a sudden slip could cause hand to move into
bit/cutting tool.

DO NOT wear loose
clothing, gloves, or jewelry. Tie back long
hair. Keep all guards in place and secure.
Always allow spindle to stop on its own. DO
NOT stop spindle using your hand or any
other object.

Chuck key,
wrenches, and other tools left on machine
can become deadly projectiles when spindle
is started. Remove all loose items or tools
used on spindle immediately after use.

Using wrong spindle
speed can cause bits/cutting tools to break
and strike operator or bystanders. Follow
recommended speeds and feeds for each
size/type of bit/cutting tool and workpiece
material.

/Cutting Tool. Firmly secure bit/

cutting tool in chuck so it cannot fly out of
spindle during operation or startup.

Drilling Preparation. To avoid loss of drilling

control or bit breakage, only drill into a flat
surface that is approximately perpendicular
to bit. Clear table of all objects before

pressed against workpiece.

Securing Table and Headstock. To avoid loss of

control leading to accidental contact with

before operating drill press.

Workpiece Control. An unsecured workpiece may

unexpectedly shift, spin out of control, or
be thrown if bit/cutting tool “grabs” during
operation. Clamp workpiece to table or in
table-mounted vise, or brace against column
to prevent rotation. NEVER hold workpiece
by hand during operation. NEVER start
machine with bit/cutting tool touching
workpiece; allow spindle to gain full speed
before drilling.

Inspecting Bit/Cutting Tool.

tools may break apart during operation
and hit operator or bystanders. Dull bits/
cutting tools increase cutting resistance
and are more likely to grab and spin/throw
workpiece. Always inspect bits/cutting tools
for sharpness, chips, or cracks before each
use. Replace dull, chipped, or cracked bits/
cutting tools immediately.

Before installing the machine, consider the
availability and proximity of the required power
supply circuit. If an existing circuit does not meet
the requirements for this machine, a new circuit
must be installed.

To minimize the risk of electrocution, fire,
or equipment damage, installation work and
electrical wiring must be done by a
or qualified service personnel
applicable electrical codes and safety standards.

The full-load current rating is the amperage
a machine draws at 100% of the rated output
power. On machines with multiple motors, this is
the amperage drawn by the largest motor or sum
of all motors and electrical devices that might
operate at one time during normal operations.

The full-load current is not the maximum
amount of amps that the machine will draw. If
the machine is overloaded, it will draw additional
amps beyond the full-load rating.

If the machine is overloaded for a sufficient
length of time, damage, overheating, or fire may
result—especially if connected to an undersized
circuit. To reduce the risk of these hazards,
avoid overloading the machine during operation
and make sure it is connected to a power supply
circuit that meets the requirements in the
following section.

This machine is prewired to operate on a power
supply circuit that has a verified ground and
meets the following requirements:

Note: The circuit requirements in this manual
are for

machine will be connected to a shared circuit
where multiple machines will be running at
the same time, consult a qualified electrician to
ensure the circuit is properly sized.

A power supply circuit includes all electrical
equipment between the main breaker box or fuse
panel in your building and the incoming power
connections inside the machine. This circuit
must be safely sized to handle the full-load
current that may be drawn from the machine for
an extended period of time. (If this machine is

Improper connection of the equipment-grounding
wire can result in a risk of electric shock. The
wire with green insulation (with or without
yellow stripes) is the equipment-grounding wire.
If repair or replacement of the power cord or
plug is necessary, do not connect the equipment­grounding wire to a live (current carrying)
terminal.

Check with an electrician or qualified service
personnel if you do not understand these
grounding requirements, or if you are in doubt
about whether the tool is properly grounded.

If you ever notice that a cord or plug is
damaged or worn, disconnect it from power, and
immediately replace it with a new one.

We do not recommend using an extension cord
with this machine. If you must use one, only
use it if absolutely necessary and only on a

Leveling machinery helps precision components,
such as bed ways, remain straight and flat
during the lifespan of the machine. Components
on an unleveled machine may slowly twist due to
the dynamic loads placed on the machine during
operation.

For best results, use a precision level that
is at least 12" long and sensitive enough to
show a distinct movement when a 0.003" shim
(approximately the thickness of one sheet of
standard newspaper) is placed under one end of
the level.

See the figure below for an example of a high
precision level.

Generally, you can either bolt your machine
to the floor or mount it on machine mounts.
Although not required, we recommend that you
secure the machine to the floor and level it while
doing so. Because this is an optional step and
floor materials may vary, hardware for securing
the machine to the floor is not included.

Lifting & Moving

This machine and its
parts are heavy! Serious
personal injury may occur
if safe moving methods are
not used. To reduce the
risk of a lifting or dropping
injury, ask others for help
and use power equipment.

To lift and place machine:

1. Move shipping crate next to intended

location of drill press, then remove top
portion of crate from shipping pallet.

2. To help balance machine when moving, move

table as close to base as possible and center
table in X-axis.

Leveling & Mounting

We strongly recommend securing your
machine to the floor if it is hardwired to the
power source. Consult with your electrician to
ensure compliance with local codes.

Anchoring machinery to the fl oor prevents
tipping or shifting and reduces vibration that
may occur during operation, resulting in a
machine that runs slightly quieter and feels more
solid.

If the machine will be installed in a
commercial or workplace setting, or if it is
permanently connected (hardwired) to the
power supply, local codes may require that it be
anchored to the fl oor.

If not required by any local codes, fastening the
machine to the fl oor is an optional step. If you
choose not to do this with your machine, we
recommend placing it on machine mounts, as
these provide an easy method for leveling and
they have vibration-absorbing pads.

Lag shield anchors with lag screws (see below)
are a popular way to anchor machinery to a
concrete fl oor, because the anchors sit fl ush with
the fl oor surface, making it easy to unbolt and
move the machine later, if needed. However,
anytime local codes apply, you MUST follow the
anchoring methodology specifi ed by the code.

PREPARATION

Power Feed Test Run

Model SB1116 comes with power feed units for
X- and Z-axis table travel. Proper operation of
the limit switches (attached to the front middle of
the table and at the base of the Z-axis power feed
unit) is important to the operation of the power
feed units. Refer to SB1116 X- and Z-Axis
Power Feed Controls on Page 5 to understand
the names and locations of components
referenced in this section.

For Machines Mfd. Since 1/21

During power feed operation, handwheels/
cranks will spin rapidly if engaged. To reduce
risk of entanglement or impact injury, always
fold in the X-axis handwheel handle and
disengage the Z-axis elevation crank when
using power feed. Failure to do so could lead
to entanglement or impact injuries.

To test run power feed units:

1. Make sure all tools, cables, and other

items are well clear of table movement and
potential direction of travel.

2. Refer to Operating Power Feed section,

beginning on Page 35, to understand how
power feeds, table locks, and limit switches
function.

3. Adjust X-axis limit stops and loosen X-axis

table locks to allow for maximum table
movement in following steps, shown in
Figure 40.

for the first time when the machine is new or if it
has been sitting idle for longer than 6 months.

Always start the spindle break-in at the lowest
speed to minimize wear if there are dry spots.
Allow the spindle to run long enough to warm
up and distribute the bearing grease, then
incrementally increase spindle speeds and repeat
this process at each speed until reaching the
maximum spindle speed. Following the break­in procedure in this progressive manner helps
minimize any potential wear that could occur

Table Locks (SB1116)

Use table locks to increase the rigidity of the
table when movement in that axis is not required
for the operation.

Table Movement

The Model SB1115 Z-axis is controlled by the
Z-axis crank handle. The table can also be moved
360° around the column.

The Model SB1116 table travels in three
directions (see Figure 43). This travel is
controlled by table handwheels and the Z-axis
crank handle or Z-axis power feed. Additionally,
the table can be moved along the X-axis with the
power feed and manually rotated 360° around
the column.

OPERATION

Spindle Downfeed

Spindle downfeed movement on the drill
press is controlled by two mechanisms: 1)
The coarse downfeed lever, and 2) the fine
downfeed handwheel (see Figure 63). Refer
to Controls & Components on Page 3 for
detailed descriptions of all downfeed controls and
components.

Fine DownfeedFine Downfeed

HandwheelHandwheel

QuillQuill

Lock LeverLock Lever

Figure 63. Downfeed control locations.Figure 63. Downfeed control locations.

Using Coarse Downfeed

Coarse downfeed is typically used for drilling,
because it allows you to quickly lower the
spindle with varying speed/pressure, and it
automatically retracts the spindle back to the top
position when released.

GraduatedGraduated

DialDial

Coarse Coarse

DownfeedDownfeed

LeversLevers

Downfeed Downfeed

SelectorSelector

KnobKnob

In order to ensure the milled surface remains
flat, the quill lock lever should be tightened after
each adjustment to ensure the spindle height
cannot move until the entire milling operation is
complete.

To engage fine downfeed, make sure the
spindle is completely stopped, and tighten the
downfeed selector knob. Rotate the fine downfeed
handwheel to raise or lower the spindle (see
Figure 63).

Setting Depth Stop

The depth stop limits the drilling depth or
downward movement of the cutting tool. The
maximum depth is 5". This is useful when
performing the same operation multiple times.

To set depth stop:

1. DISCONNECT MACHINE FROM POWER!

2. Install tooling (refer to Page 37 for SB1115

or Page 39 for SB1116), then make sure
spindle is drawn all the way up into
headstock.

3. Loosen Z-axis table lock, and raise table
until it is approximately

1

⁄8" below tooling.

To engage coarse downfeed, make sure the
spindle is completely stopped, and loosen the
downfeed selector knob shown in Figure 63.

Note: To maintain control of the upward spindle
travel, always continue holding the coarse
downfeed levers until the spindle returns to the
top position. Letting go of the levers too soon will
cause the spindle to retract too quickly and slam
up into the headstock.

Using Fine Downfeed

Fine downfeed is typically used for precise,
non-retractable Z-axis positioning of a cutter
or end-mill when milling a flat surface across
the face of a workpiece. The fine downfeed
handwheel is equipped with a graduated collar
(see Figure 63) with 0.001" increments. Each
complete revolution of the handwheel equals

0.100".

4. Rotate depth stop adjustment knob until top
of depth stop pointer is level with desired
depth as listed on scale (see Figure 64).

Note: The depth stop scale functions as a

general guide only. It is not intended for
tight-tolerance, precision results. To calibrate
the depth stop see Calibrating Depth Stop
on Page 58.

Spindle Speed

Using the correct spindle speed is important
for safe and satisfactory results, as well as
maximizing tool life.

To set the spindle speed for your operation, you
will need to: 1) Determine the best spindle speed
for the cutting task, and 2) configure the spindle
speed range lever and spindle speed dial to
produce the required spindle speed.

Determining Spindle Speed

Many variables affect the optimum spindle speed
to use for any given operation, but the two most
important are the recommended cutting speed
for the workpiece material and the diameter of
the cutting tool, as noted in the formula shown in
Figure 65.

*Recommended

Cutting Speed (FPM) x 12

Tool Dia. (in inches) x 3.14

*Double if using carbide cutting tool

Figure 65. Spindle speed formula for milling.Figure 65. Spindle speed formula for milling.

Cutting speed, typically defined in feet per
minute (FPM), is the speed at which the edge of a
tool moves across the material surface.

Spindle

Speed
(RPM)

Setting Spindle Speed

Use the chart below or the one on the headstock
when setting the spindle speed.

Spindle Speed Range Range Lever

0–350 RPM L

0–2500 RPM H

Change spindle speed range ONLY when the
spindle is completely stopped. Otherwise,
machine damage could occur.

To set spindle speed:

1. With spindle completely stopped, position

spindle speed range lever (see Figure 66) to
high or low ("H" or "L") range.

Note: If necessary, rotate the spindle by

hand to mesh the gears when changing speed
range.

2. Rotate spindle speed dial (see Figure 66)
to approximate desired spindle speed, then
turn machine ON. If necessary, adjust
spindle speed dial with machine running to
fine-tune spindle speed.

Spindle SpeedSpindle Speed

Range leverRange lever

A recommended cutting speed is an ideal speed
for cutting a type of material in order to produce
the desired finish and optimize tool life.

The books Machinery’s Handbook or Machine
Shop Practice, and some internet sites, provide
excellent recommendations for which cutting
speeds to use when calculating the spindle speed.
These sources also provide a wealth of additional
information about the variables that affect
cutting speed and they are a good educational
resource.

Also, there are a large number of easy-to-use
spindle speed calculators that can be found on
the internet. These sources will help you take
into account the applicable variables in order
to determine the best spindle speed for the
operation.

OPERATION

Calculating Spindle Speed for Drilling

The chart shown in Figure 67 is intended as
a guide only. Always follow the manufacturer's
speed recommendations if provided with your
drill bits, cutters, or hole saws. Exceeding the
recommended speeds may be dangerous to the
operator or cause damage to the tooling.

The speeds shown here are intended to get you
started. The optimum speed will always depend
on various factors, including tool diameter,
drilling pressure, material hardness, material
quality, and desired finish.

Often, when drilling materials other than wood,
some type of lubrication is necessary.

Lubrication Suggestions

Wood ............................................................... None

Plastics ................................................Soapy Water

Brass .................................Water-Based Lubricant

Aluminum ..................... Paraffin-Based Lubricant

Mild Steel .............................. Oil-Based Lubricant

Larger bits turning at slower speeds tend to
grab the workpiece aggressively. This can
result in the operator's hand being pulled into
the bit or the workpiece being thrown with
great force. Always clamp the workpiece to
the table to prevent injuries.

MAINTENANCE

Maintenance Schedule

Always disconnect
machine from power before
performing maintenance or
serious personal injury may
result.

For optimum performance from your machine,
follow this maintenance schedule and refer to
any specific instructions given in this section.

Ongoing

To help minimize your risk of injury and
maintain proper machine operation, if you
ever observe any of the items below shut the
machine down immediately, disconnect it from
power, and fix the problem before continuing
operations.

• Loose mounting bolts or fasteners.

• Worn, frayed, cracked, or damaged wires.

• Any other unsafe condition.

Before Beginning Operations

• Turn the spindle direction switch to the
OFF (middle) position to prevent spindle
startup when connected to power (see
Page 3).

• (SB1116) Make sure the X- and Z-axis
power feed units are turned OFF to
prevent unintentional table movement
when connected to power (see Page 35).

• Perform lubrication tasks as directed in
the Lubrication section, beginning on
Page 49.

• Check table movement in all three axis
directions for loose/tight gibs. Adjust the
gibs if necessary (see Page 54).

Daily, After Operations

• Disconnect the machine from power.

• Vacuum/clean all debris from table, slides,
and base.

• Wipe down all unpainted or machined
surfaces with a good quality rust
preventative.

Cleaning & Protecting

Regular cleaning is one of the most important
steps in taking good care of this machine. Each
operator is responsible for cleaning the machine
immediately after using it or at the end of the
day. We recommend that the cleaning routine
be planned into the workflow schedule, so that
adequate time is set aside to do the job right.

Typically, the easiest way to clean debris from
the ways and table is to use a wet/dry shop
vacuum that is dedicated for this purpose only.
Small metal chips leftover after vacuuming can
be wiped up with a slightly oiled rag. Avoid using
compressed air to blow off metal chips, as this
may drive them deeper into moving surfaces and
could cause sharp chips to fly into your face or
hands.

Besides the ways and elevation leadscrew, all
other unpainted and machined surfaces should
be wiped down daily to keep them rust-free and
in top condition. This includes any surface that
could be vulnerable to rust if left unprotected
(this especially includes any parts that may be
exposed to water soluble cutting fluids). Typically
with these parts, a thin film of oil is all that is
necessary for protection.

Keep tables rust-free with ISO 68 way oil (see
Page 44).

Lubrication

This machine has numerous moving metal-to­metal contacts that require regular and proper
lubrication to ensure efficient and long-lasting
operation, and to protect your investment.

Other than the lubrication points covered in
this section, all other bearings are internally
lubricated and sealed at the factory. Simply leave
them alone unless they need to be replaced.

Before performing any lubrication task,
DISCONNECT MACHINE FROM POWER!

IMPORTANT: Before adding lubricant, clean any
debris and grime from the fill hole/grease fitting
and the immediate area to prevent contamination
of the new lubricant.

Use the schedule and information shown in
Figure 83 as a guide for lubrication tasks.
Follow the referenced sections on the following
pages for detailed instructions.

Failure to follow reasonable lubrication
practices as instructed in this manual could
lead to premature failure of the machine and
will void the warranty.

Oil Amount ............................................. Thin Coat

Lubrication Frequency ............8 Hrs. of Operation

Use the controls to access all surfaces (see
Figures 84–85), then clean them with mineral
spirits, shop rags, and, where appropriate,
brushes.

When dry, apply a thin coat of oil to the surfaces.
Use clean brushes to apply oil to the grooves
of the column rack. Move each component
through the entire path of travel several times to
distribute the lubricant.

Note: Take care not to remove the quill rack
grease without re-applying it.

The following recommended lubrication

Adjusting Gibs (SB1116)

Gibs are tapered lengths of metal that are
sandwiched between two moving surfaces. Gibs
control the gap between these surfaces and how
they slide past one another. Correctly adjusting
the gibs is critical to producing good milling
results.

Tight gibs make table movement more
accurate but stiff. Loose gibs make moving the
table sloppy but easier to do. The goal of gib
adjustment is to remove unnecessary sloppiness
without causing the ways to bind.

Gibs are adjusted with gib screws (see Figures
97–98) that move the tapered gib back-and-forth
to increase or decrease the friction pressure
between the sliding surfaces. The process of
properly adjusting the gibs requires trial-and­error and patience.

Adjusting Leadscrew Backlash (SB1116)

Leadscrew backlash is the amount of motion or
"play" in leadscrew rotation before the attached
device begins to move. Leadscrews will always
have a certain amount of backlash that will
increase with normal wear.

Generally, 0.005"–0.010" leadscrew backlash
is acceptable to ensure smooth movement and
reduce the risk of premature thread wear.
However, if you find it necessary to adjust
leadscrew backlash, perform the procedures
listed below.

Tool Needed Qty

T-Handle Hex Wrench 5mm .................................1

To adjust leadscrew backlash:

Tighten or loosen the cap screws on the
leadscrew nuts shown in Figures 99–100, then
test the amount of backlash by slowly rocking the
handwheels back-and-forth. Repeat if necessary.

Tramming Spindle

After positioning the head at an angle and when
your operation requires that the spindle axis be
precisely perpendicular to the table, you must
tram or align the spindle with the table to ensure
the spindle is exactly 90° to the table.

This procedure involves mounting a dial test
indicator to the quill or spindle, rotating it
around the table, and adjusting the spindle
axis (Z-axis) 90° to the table X- and Y-axis, as
illustrated in Figure 101 below.

Spindle

90º

Table

Note: A precision-ground plate can be substituted
for the parallel blocks. Keep in mind that the
farther the indicator point can be placed from
the spindle axis, the more accurate the alignment
measurements will be.

To tram spindle to table:

1. DISCONNECT MACHINE FROM POWER!

2. Prepare machine for tramming by

performing following tasks:

• Verify the table is clean by running your
hand over the top of it. If necessary, stone
the table to remove all nicks and burrs,
then clean off all debris.

• Position the table for the operation you
intend to perform after tramming—
preferably centered with the saddle.

• Tighten any table, knee, quill, or ram
locks that should be tight during the
intended operation.

Figure 101. Spindle Z-axis perpendicular to the table Figure 101. Spindle Z-axis perpendicular to the table

X- and Y-axis.X- and Y-axis.

We encourage you to research the many
variations of spindle tramming to find the one
that works best for you. If you do not already
have a preference for performing this operation,
use the following widely-used procedure for
accurately tramming the spindle to the table.

Keep in mind that all workpiece top surfaces are
not exactly parallel with the table top. You may
choose to tram the spindle to the top surface of
the workpiece after it is mounted rather than
tramming the spindle to the table.

5. To measure spindle alignment along X-axis,

place parallel block directly under spindle
and indicator across length of table, as
illustrated in figure below.

Note: If you must re-position the quill or the

knee to accommodate the above step, then
review the tasks in Step 2 to make sure the
machine is properly prepared for tramming.

Note: Your general goal in the next steps

should be to get the difference of the indicator
readings between the ends of the parallel bar
down to 0.0005". However, the acceptable
variance will depend on the requirements for
your operation.

Note: Keep one of the rotation lock bolts just

snug so the head does not move loosely while
you adjust it. Remember to tighten all the
rotation lock bolts after adjusting the head.

9. Rotate spindle so indicator point rests on

parallel bar, as illustrated in figure above,
then zero the dial.

10. Rotate spindle so that indicator point rests

on other end of bar in same manner, then
read dial.

6. Rotate spindle by hand so that indicator

point rests on one end of parallel block, then
zero the dial.

7. Rotate spindle so that indicator point rests

in same manner on other end of block, then
read dial.

— If the indicator dial still reads zero or is

within the acceptable variance, continue
on with Step 8.

— If the indicator dial has moved from zero

beyond the acceptable variance, you will
need to compensate for that amount by
rotating the head left or right. Repeat
Steps 6–7 until you are satisfied with the
spindle axis alignment along the table
X-axis.

— If the indicator dial still reads zero or

is within the acceptable variance, the
spindle is precisely perpendicular to the
table in both the X- and Y-axis, and the
tramming procedure is complete.

— If the indicator dial has moved from zero

beyond the acceptable variance, you will
need to compensate for that amount by
tilting the head forward or backward.
Repeat Steps 9–10 until you are satisfied
with the spindle axis alignment along the
table Y-axis.

Note: Keep one of the tilt lock bolts just snug

so the head does not move loosely while you
adjust it. Remember to tighten all the tilt lock
bolts after adjusting the head.
