INTRODUCTION
Machine Description
Manual Accuracy
We are proud to provide a high-quality owner’s
manual with your new machine!
these milling machines are designed to remove
material from a metal workpiece that is secured
to the work table or a mill vise. the cutting tool
is fixed to the rotating spindle and moved into the
workpiece by lowering the spindle or moving the
table. the table moves in three axes (X-, y-, and
z-axis) with a power feed assist for the X-axis.
We made every effort to be exact with the instruc-
tions, specifications, drawings, and photographs
contained inside. sometimes we make mistakes,
but our policy of continuous improvement also
means that sometimes the machine you receive
will be slightly different than what is shown in
the manual.
spindle downfeed options are rapid (coarse)
control or slow (fine) control with adjustable auto-
downfeed controls.
if you find this to be the case, and the difference
between the manual and machine leaves you
confused about a procedure, check our website
for an updated version. We post current manuals
and manual updates for free on our website at
Both models offer a wide range of spindle speeds
and three auto-downfeed rates.
the wide range of cutting tools and optional
equipment available, combined with the flexible
features of these milling machines, make possible
countless metalworking operations.
Alternatively, you can call our technical support
for help. Before calling, please write down the
Manufacture Date and Serial Number stamped
into the machine id label (see below). this infor-
mation helps us determine if updated documenta-
tion is available for your machine.

can be shocked, burned, or killed by touching live
electrical components or improperly grounded
machinery. to reduce this risk, only allow qualified
service personnel to do electrical installation or
repair work, and always disconnect power before
accessing or exposing electrical equipment.
TRAINED OPERATORS ONLy. untrained oper-
ators have a higher risk of being hurt or killed.
only allow trained/supervised people to use this
machine. When machine is not being used, dis-
connect power, remove switch keys, or lock-out
machine to prevent unauthorized use—especially
around children. Make workshop kid proof!
DISCONNECT POWER FIRST. Always discon-
nect machine from power supply BeFore making
adjustments, changing tooling, or servicing machine.
this prevents an injury risk from unintended startup
or contact with live electrical components.
DANGEROUS ENVIRONMENTS. do not use
machinery in areas that are wet, cluttered, or have
poor lighting. operating machinery in these areas
greatly increases the risk of accidents and injury.
EyE PROTECTION. Always wear Ansi-approved
safety glasses or a face shield when operating or
observing machinery to reduce the risk of eye
injury or blindness from flying particles. everyday
eyeglasses are not approved safety glasses.
MENTAL ALERTNESS REQUIRED. Full mental
alertness is required for safe operation of machin-
ery. never operate under the influence of drugs or
alcohol, when tired, or when distracted.

it will do the job safer and better at the rate for
which it was designed.
NEVER STAND ON MACHINE. serious injury
may occur if machine is tipped or if the cutting
tool is unintentionally contacted.
HAzARDOUS DUST. dust created while using
machinery may cause cancer, birth defects, or
long-term respiratory damage. Be aware of dust
hazards associated with each workpiece material,
and always wear a niosh-approved respirator to
reduce your risk.
STAbLE MACHINE. unexpected movement dur-
ing operation greatly increases risk of injury or
loss of control. Before starting, verify machine is
stable and mobile base (if used) is locked.
USE RECOMMENDED ACCESSORIES. Consult
this owner’s manual or the manufacturer for rec-
ommended accessories. using improper acces-
sories will increase the risk of serious injury.
HEARING PROTECTION. Always wear hear-
ing protection when operating or observing loud
machinery. extended exposure to this noise
without hearing protection can cause permanent
hearing loss.
UNATTENDED OPERATION. to reduce the
risk of accidental injury, turn machine OFF and
ensure all moving parts completely stop before
walking away. never leave machine running
while unattended.
REMOVE ADJUSTING TOOLS. tools left on
machinery can become dangerous projectiles
upon startup. never leave chuck keys, wrenches,
or any other tools on machine. Always verify
removal before starting!
MAINTAIN WITH CARE. Follow all maintenance
instructions and lubrication schedules to keep
machine in good working condition. A machine
that is improperly maintained could malfunction,
leading to serious personal injury or death.
USE CORRECT TOOL FOR THE JOb. only use
this tool for its intended purpose—do not force
it or an attachment to do a job for which it was
not designed. never make unapproved modifica-
tions—modifying tool or using it differently than
intended may result in malfunction or mechanical
failure that can lead to personal injury or death!
CHECK DAMAGED PARTS. regularly inspect
machine for any condition that may affect safe
operation. immediately repair or replace damaged
or mis-adjusted parts before operating machine.
AWKWARD POSITIONS. Keep proper footing
and balance at all times when operating machine.
do not overreach! Avoid awkward hand positions
that make workpiece control difficult or increase
the risk of accidental injury.
MAINTAIN POWER CORDS. When disconnect-
ing cord-connected machines from power, grab
and pull the plug—not the cord. pulling the cord
may damage the wires inside. do not handle
cord/plug with wet hands. Avoid cord damage by
keeping it away from heated surfaces, high traffic
areas, harsh chemicals, and wet/damp locations.
CHILDREN & bySTANDERS. Keep children and
bystanders at a safe distance from the work area.
stop using machine if they become a distraction.
EXPERIENCING DIFFICULTIES. if at any time
you experience difficulties performing the intend-
ed operation, stop using the machine! Contact our
technical support at (570) 546-9663.
GUARDS & COVERS. guards and covers reduce
accidental contact with moving parts or flying
debris. Make sure they are properly installed,
undamaged, and working correctly.

Circuit Requirements for 220V
This machine is prewired to operate on a 220V
power supply circuit that has a verified ground and
meets the following requirements:
Before installing the machine, consider the avail-
ability 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 an electrican or
qualified service personnel in accordance with all
applicable codes and standards.
Nominal Voltage .............................. 220V/240V
Cycle..........................................................60 Hz
Phase.................................................... 3-Phase
Power Supply Circuit ......................... 15 Amps
Plug/Receptacle ............................NEMA 15-15
A power supply circuit includes all electrical
equipment between the breaker box or fuse panel
in the building and the machine. The power sup-
ply circuit used for this machine must be sized to
safely handle the full-load current drawn from the
machine for an extended period of time. (If this
machine is connected to a circuit protected by
fuses, use a time delay fuse marked D.)
Electrocution, fire, or
equipment damage may
occur if machine is not
correctly grounded and
connected to the power
supply.
Full-Load Current Rating
For your own safety and protection of
property, consult an electrician if you are
unsure about wiring practices or electrical
codes in your area.
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.
Note: The circuit requirements listed in this man-
ual apply to a dedicated circuit—where only one
machine will be running at a time. If this machine
will be connected to a shared circuit where mul-
tiple machines will be running at the same time,
consult a qualified electrician to ensure that the
circuit is properly sized for safe operation.
G0747 Full-Load Current Rating ....... 7.9 Amps
G0748 Full-Load Current Rating.......6.6 Amps
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 over-
loading the machine during operation and make
sure it is connected to a power supply circuit that
meets the requirements in the following section.

Grounding Instructions
This machine MUST be grounded. In the event
of certain malfunctions or breakdowns, grounding
reduces the risk of electric shock by providing a
path of least resistance for electric current.
Serious injury could occur if you connect
the machine to power before completing the
setup process. DO NOT connect to power
until instructed later in this manual.
the power cord and plug specified under “Circuit
requirements for 220V” on the previous page
has an equipment-grounding wire and a ground-
ing prong. the plug must only be inserted into
a matching receptacle (outlet) that is properly
installed and grounded in accordance with all
local codes and ordinances (see figure below).
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 nec-
essary, do not connect the equipment-grounding
wire to a live (current carrying) terminal.
Check with a qualified electrician or service per-
sonnel 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, discon-
nect it from power, and immediately replace it with
a new one.

Extension Cords
We do not recommend using an extension cord
with this machine. If you must use an extension
cord, only use it if absolutely necessary and only
on a temporary basis.
Figure 1. typical 15-15 plug and receptacle.
Serious injury could occur if you connect
the machine to power before completing the
setup process. DO NOT connect to power
until instructed later in this manual.
Extension cords cause voltage drop, which may
damage electrical components and shorten motor
life. Voltage drop increases as the extension cord
size gets longer and the gauge size gets smaller
(higher gauge numbers indicate smaller sizes).
Any extension cord used with this machine must
contain a ground wire, match the required plug
and receptacle, and meet the following require-
ments:
Minimum Gauge Size...........................14 AWG
Maximum Length (Shorter is better).......50 ft.
No adapter should be used with the
required plug. If the plug does not fit the
available receptacle, or the machine must
be reconnected for use on a different type
of circuit, the reconnection must be made
by a qualified electrician and comply with all
local codes and ordinances.

Cleanup
Gasoline or products
with low flash points can
explode or cause fire if
used to clean machin-
ery. Avoid cleaning with
these products.
The unpainted surfaces of your machine are
coated with a heavy-duty rust preventative that
prevents corrosion during shipment and storage.
This rust preventative works extremely well, but it
will take a little time to clean.
Be patient and do a thorough job cleaning your
machine. The time you spend doing this now will
give you a better appreciation for the proper care
of your machine's unpainted surfaces.
Many cleaning solvents
are toxic if concentrat-
ed amounts are inhaled.
Only work in a well-venti-
lated area.
There are many ways to remove this rust preven-
tative, but the following steps work well in a wide
variety of situations. Always follow the manufac-
turer’s instructions with any cleaning product you
use and make sure you work in a well-ventilated
area to minimize exposure to toxic fumes.
NOTICE
Avoid chlorine-based solvents, such as
acetone or brake parts cleaner, that may
damage painted surfaces. Test all cleaners
in an inconspicuous area before using to
make sure they will not damage paint.
Before cleaning, gather the following:
•
•
•
•
Disposable Rags
Cleaner/degreaser (WD•40 works well)
Safety glasses & disposable gloves
Plastic paint scraper (optional)
T23692—Orange Power Degreaser
A great product for removing the waxy shipping
Basic steps for removing rust preventative:
grease from your machine during clean up.
1. Put on safety glasses.
2. Coat the rust preventative with a liberal
amount of cleaner/degreaser, then let it soak
for 5–10 minutes.
3. Wipe off the surfaces. If your cleaner/degreas-
er is effective, the rust preventative will wipe
off easily. If you have a plastic paint scraper,
scrape off as much as you can first, then wipe
off the rest with the rag.
4. Repeat Steps 2–3 as necessary until clean,
then coat all unpainted surfaces with a quality
metal protectant to prevent rust.

Site Considerations
Weight Load
Physical Environment
refer to the Machine Data Sheet for the weight
of your machine. Make sure that the surface upon
which the machine is placed will bear the weight
of the machine, additional equipment that may be
installed on the machine, and the heaviest work-
piece that will be used. Additionally, consider the
weight of the operator and any dynamic loading
that may occur when operating the machine.
the physical environment where the machine is
operated is important for safe operation and lon-
gevity of machine components. For best results,
operate this machine in a dry environment that is
free from excessive moisture, hazardous chemi-
cals, airborne abrasives, or extreme conditions.
extreme conditions for this type of machinery are
generally those where the ambient temperature
range exceeds 41°–104°F; the relative humidity
range exceeds 20–95% (non-condensing); or the
environment is subject to vibration, shocks, or
bumps.
Space Allocation
Consider the largest size of workpiece that will
be processed through this machine and provide
enough space around the machine for adequate
operator material handling or the installation of
auxiliary equipment. With permanent installations,
leave enough space around the machine to open
or remove doors/covers as required by the main-
tenance and service described in this manual.
See below for required space allocation.
Electrical Installation
place this machine near an existing power source.
Make sure all power cords are protected from
traffic, material handling, moisture, chemicals,
or other hazards. Make sure to leave access to
a means of disconnecting the power source or
engaging a lockout/tagout device, if required.
Lighting
Children or untrained people
may be seriously injured by
this machine. Only install in an
access restricted location.
lighting around the machine must be adequate
enough that operations can be performed safely.
shadows, glare, or strobe effects that may distract
or impede the operator must be eliminated.

Note: After re-positioning the ram and head-
stock, make sure they are locked in place to
prevent unexpected movement during lifting.
Lifting & Placing
Make sure the four turret lock bolts (two on
either side of the ram, see Figure 6) are
torqued to 47 ft/lbs. to keep the ram from
unexpectedly moving from the force of the
lifting straps.
HEAVy LIFT!
Straining or crushing injury
may occur from improperly
lifting machine or some of
its parts. To reduce this risk,
get help from other people
and use a fork lift (or other
lifting equipment) rated for
weight of this machine.
turret locking Bolts
(2 of 4)
power lifting equipment (refer to Page 16) and
at least two other people are required to lift and
place the mill.
To lift and move the mill:
1. remove the crate from the shipping pallet,
then move the mill, while it is still on the pal-
let, to the installation location.
Figure 6. locations of turret locking bolts.
3. place the lifting straps under the ram and
connect them to the safety hook, as illus-
trated in Figure 5.
2. rotate the ram 180° so the headstock is fac-
ing backwards (see Figure 5), then rotate the
head upright.
Note: Place protective material between the
straps and the mill to protect the ram and
ways, and to keep from cutting the lifting
straps.
refer to Head Movement on Page 29 and
Ram Movement on Page 31 for detailed
instructions to help with this step.
4. unbolt the mill from the shipping pallet.
5. With other people steadying the load to keep
it from swaying, lift the mill a couple of inches.
—if the mill tips to one side, lower it to the
ground and adjust the ram or table to bal-
ance the load. Make sure to re-tighten the
lock levers and bolts before lifting the mill
again.
—if the mill lifts evenly, remove the shipping
pallet and lower the mill.

bolting to Concrete Floors
Leveling & Mounting
Anchor studs and lag shield anchors with lag
screw (Figure 8) are two popular methods for
anchoring an object to a concrete floor. We sug-
gest you research the many options and methods
for mounting your machine and choose the best
that fits your specific application
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 materi-
als may vary, hardware for securing the machine
to the floor is not included.
Anchor stud
Unless otherwise specified by your local
codes, this machine MUST be secured to
the floor if it is permanently connected
(hardwired) to the power supply.
lag shield
Anchor
Leveling
lag screw
leveling machinery helps precision components,
such as dovetail 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.
Figure 8. typical fasteners for mounting to
concrete floors.
Machine Mounts
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 (approxi-
mately the thickness of one sheet of standard
newspaper) is placed under one end of the level.
Machine mounts (see Figure 9 for an example)
provide the advantage of fast leveling and vibra-
tion reduction. the large size of the foot pads
distributes the weight of the machine to reduce
strain on the floor.
see Figure 7 for an example of a high precision
level available from grizzly.

SECTION 4: OPERATIONS
To complete a typical operation, the operator
does the following:
Operation Overview
1. examines the workpiece to make sure it is
suitable for milling.
The purpose of this overview is to provide the nov-
ice machine operator with a basic understanding
of how the machine is used during operation, so
the machine controls/components discussed later
in this manual are easier to understand.
2. Firmly clamps the workpiece to the table or a
mill vise.
3. installs the correct cutting tool for the opera-
tion.
Due to the generic nature of this overview, it is
not intended to be an instructional guide. To learn
more about specific operations, read this entire
manual and seek additional training from expe-
rienced machine operators, and do additional
research outside of this manual by reading "how-
to" books, trade magazines, or websites.
4. uses the manual downfeed and table con-
trols to correctly position the cutting tool and
workpiece for the operation. if the X-axis
power feed will be used during the operation,
the operator confirms the speed and length of
table movement required.
5. Configures the mill for the correct spindle
speed of the operation.
To reduce your risk of
serious injury, read this
entire manual bEFORE
using machine.
6. puts on personal protective gear, and makes
sure the workpiece and table are clear of all
tools, cords, and other items.
7. starts the spindle rotation and performs the
operation.
To reduce risk of eye or face injury from
flying chips, always wear approved safety
glasses and a face shield when operating
this machine.
8. turns the mill OFF.
If you are not experienced with this type
of machine, WE STRONGLy RECOMMEND
that you seek additional training outside of
this manual. Read books/magazines or get
formal training before beginning any proj-
ects. Regardless of the content in this sec-
tion, Grizzly Industrial will not be held liable

the procedures for setting the spindle speed for
the Models g0747 and Model g0748 differ. use
the appropriate section on the following pages for
your mill when selecting the speed range.
Spindle Speed
using the correct spindle speed is important for
safe and satisfactory results, as well as maximiz-
ing tool life.
To avoid damaging the spindle, gears, or
cutting tools when setting the spindle speed
range:
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 mill con-
trols to match the closest spindle speed.
• Spindle rotation must be turned OFF and
the spindle must be at a complete stop
bEFORE you change the spindle speed
range.
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 Figure 26:
• To avoid damaging the moving parts
inside the headstock, never start spindle
rotation without the range selector detent
pin firmly seated in either the high or low
position.
• When the spindle speed range is changed,
the spindle rotation direction reverses.
you will need to either change the cutting
tool to match the direction of spindle rota-
tion or use the spindle direction switch to
compensate for the reversal.
*Recommended
Cutting Speed (FPM) x 12
= RPM
Tool Diameter (in inches) x 3.14
*
Double if using carbide cutting tool
Figure 26. 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.
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, pro-
vide 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 all applicable variables to determine the
best spindle speed for the operation.

Setting Model G0748 Spindle Speed
the Model g0748 has variable spindle speeds
from 60 to 4200 rpM. setting the spindle speed
involves 1) selecting the spindle speed range,
and 2) using the variable-speed handwheel to
select the spindle speed.
For the Model G0748 ONLy, always make
sure that the spindle rotation has started
and is at a constant speed before using
the variable-speed handwheel to adjust the
spindle speed. Otherwise, the moving parts
inside the belt housing could be damaged
and void the warranty.
To set the Model G0748 spindle speed:
1. Make sure the spindle is completely stopped.
4. slowly rotate the speed handwheel shown
in Figure 33 until the desired speed is dis-
played in the speed indicator window for the
speed range selected.

Spindle Downfeed
When spindle rotation is reversed, either
by changing the spindle speed range or by
using the spindle direction switch, the direc-
tion of spindle auto-downfeed will reverse.
spindle downfeed movement on the mill is con-
trolled by three mechanisms: 1) the coarse
downfeed lever, 2) the fine downfeed handwheel,
and 3) the auto-downfeed system.

4. Make sure the quill lock lever is loose so that
the quill can easily move.
Coarse Downfeed
use the coarse downfeed lever to quickly move
the spindle manually.
5. rotate the coarse downfeed lever around the
hub to control the depth of the spindle.
To use the coarse downfeed:
1. Make sure the spindle is completely stopped.
Fine Downfeed
1. Make sure the spindle is completely stopped.
2. pull the downfeed selector knob out, then
rotate it clockwise until the knob pin seats in
the forward manual (disengaged) detent (see

3. set the auto-downfeed direction pin in the
neutral (middle) position to disengage the
fine downfeed handwheel from the auto-
downfeed gears.
4. position the downfeed stop for the spindle
depth that is correct for your operation, then
secure it in place with the locking wheel.
5. use the coarse downfeed lever to lower
the spindle slightly until you can pull the
fine downfeed clutch lever out to the left
and it locks in place. this will engage the
fine downfeed handwheel with the quill and
spindle.

3. Make sure the pin of the coarse downfeed
lever hub is engaged with one of the detents
on the downfeed sleeve (see Figure 36).
6. to lower the spindle, rotate the fine downfeed
handwheel. When the quill dog meets the
downfeed stop, the clutch lever will disen-
gage and the spindle will return to the top.

4. position the auto-downfeed direction pin in
the center of the handwheel for the spindle
travel that is correct for your operation. if nec-
essary, rock the fine downfeed handwheel
back-and-forth to move the pin all the way in
or out.
Auto-Downfeed
When using the auto-downfeed system, the spin-
dle will move in the direction you choose with the
auto-downfeed direction pin. When the quill dog
reaches the top or meets the downfeed stop, the
downfeed clutch lever will release. then, if the
spindle was traveling upward, the movement will
simply stop. if the spindle was traveling down-
ward, then the spindle will move back to the top
at a rate controlled by the return spring on the left
side of the head.
Note: The direction pin has three positions:
1) In for one downfeed direction, 2) middle
for neutral or no movement, and 3) out for
the reverse direction. The direction of spindle
travel for the in and out positions is relative to
the direction of spindle rotation. Keep in mind
that spindle rotation and downfeed direction
will reverse when the spindle speed range is
changed.
To use the auto-downfeed:
1. Make sure the spindle is completely stopped.
2. pull the downfeed selector knob out, then
rotate it clockwise until the knob pin seats
in the auto-downfeed (engaged) detent (see
Figure 37).
5. Make sure the clutch lever is all the way to
the right in the disengaged position so that
the spindle will not travel when rotation is
started.
Note: It may be necessary to turn the spindle
by hand as you move the selector to enable
the gears to mesh.
Note: We recommend that you complete
the remaining steps without a cutting tool
installed, without a workpiece in place, and
the table lower than the maximum spindle
downfeed travel. This will enable you to test
and confirm the settings before beginning the
actual cutting operation.
Auto-Downfeed (Engaged) Position
To avoid damage to the system gearing,
never use the auto-downfeed system with
spindle speeds over 1750 RPM.
6. set the mill for the correct spindle speed,
then begin spindle rotation.

ALWAyS start spindle rotation before using
auto-downfeed to avoid the risk of gear
damage.
After turning the spindle switch OFF, move the
brake lever to bring the spindle to a full stop (see
Figures 39–40).
7. select one of the three downfeed rates by
pulling the knob of the auto-downfeed rate
selector out, position the selector over the
appropriate detent, then release the knob.
Make sure the pin is firmly seated by attempt-
ing to move the selector without pulling the

Protecting
Schedule
For optimum performance from your machine,
follow this maintenance schedule and refer to any
specific instructions given in this section.
regular cleaning is one of the most important
steps in taking good care of this mill. each opera-
tor is responsible for cleaning the machine imme-
diately 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.
Ongoing
to maintain a low risk of injury and 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.
typically, the easiest way to clean swarf from the
ways and table is to use a wet/dry shop vacuum
that is dedicated for this purpose only. the small
chips leftover after vacuuming can be wiped up
with a slightly oiled rag. Avoid using compressed
air to blow off chips, as this may drive them deep-
er into moving surfaces and could cause sharp
chips to fly into your face or hands.

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

contacts that require regular and proper lubrica-
tion to ensure efficient and long-lasting operation,
and to protect your investment.

Adjusting Gibs
gibs are tapered lengths of metal that are sand-
wiched between two moving surfaces. gibs con-
trol the gap between these surfaces and how they
slide past one another. Correctly adjusting the
gibs is critical to producing good milling results.
table gib &
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.
Adjustment screw
Figure 62. table gib and adjustment screw
underneath left side of table.
gibs are adjusted with a screw on each end of
the gib, 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-and-error
and patience.

2. loosen the two cap screws on the X-axis
leadscrew nut accessed from underneath the

leadscrew backlash is the amount of motion the
leadscrew rotates 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,

tuted 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.
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.
To tram the spindle to the table:
1. disConneCt Mill FroM poWer!
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-axes, as illustrated in
Figure 69.
2. prepare the mill for tramming by performing
the 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 milling 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
milling operation.

We encourage you to research the many varia-
tions of spindle tramming to find the one that

preference for performing this operation, use the
following widely-used procedure for accurately
tramming the spindle to the table.

5. to measure spindle alignment along the
X-axis, place the parallel block directly under
the spindle and indicator across the length of
the table, as illustrated in Figure 71.
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.
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
mill 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.
9. rotate the spindle so the indicator point rests
on the parallel bar, as illustrated in Figure 72,
then zero the dial.
10. rotate the spindle so that the indicator point
rests on the other end of the bar in the same
manner, then read the dial.
6. rotate the spindle by hand so that the indi-
cator point rests on one end of the parallel
block, as illustrated in Figures 70–71, then
zero the dial.
—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-axes, and the tramming
procedure is complete.
7. rotate the spindle so that the indicator point
rests in the same manner on other end of the
block, then read the dial.
—if the indicator dial has moved from zero
beyond the acceptable variance, you will
need to compensate for that amount by tilt-
ing the head forward or backward. repeat
Steps 9–10 until you are satisfied with
the spindle axis alignment along the table
y-axis.
—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.
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.
