INTRODUCTION

About This Machine

For Machines Mfg. Since 8 /09

Capabilities

This 6 x 12" Surface Grinder allows you to
smooth the surface of metallic workpieces. It
utilizes a table that moves on a horizontal plane
and a grinding wheel that moves along a vertical
axis. By mounting a workpiece to the table, then
moving the table and the grinding wheel during
the grinding process, extremely small amounts of
material can be removed to create high-tolerance
flat surfaces.

One example of this type of work may occur
when the table surface of a metalworking or
woodworking machine needs to be made perfectly
flat. By removing the table from the machine and
processing it with a surface grinder, a perfectly
flat surface can be created.

Another example of this type of work often
occurs in the automotive industry. When a head
gasket needs replacing, it is common practice
to resurface the engine head to make sure it is
perfectly flat, in case any warping has occurred.
The head can be precisely ground using a surface
grinder.

Features

Now that you know the basics of what this
machine can do, take a minute to consider its
features.

The SB1023 is equipped with easy-to-reach
front-mounted handwheels for controlling table
movement.

The table travels in the longitudinal direction
on a ball-bearing supported table, driven by a
rack-and-pinion mechanism. The stand doubles
as a storage cabinet where you can keep the
necessary tools and extra grinding wheels right
where you need them.

The included diamond dresser is used to true the
grinding wheel, ensuring high-precision results.

Aside from these features, we designed this
machine to be extremely solid and durable.
With thick, hardened steel ways, cast-iron
construction, and Allen Bradley electrical
components, this South Bend surface grinder is
built to last.

Model SB1023

SAFETY

For Machines Mfg. Since 8 /09

Additional Surface Grinder Safety

1. Eye Protection: Grinding causes small

particles to become airborne at a high
rate of speed. ALWAYS wear eye
protection when using this machine.

2. Wheel Speed Rating: Wheels operated at

a faster speed than rated for may break
or fly apart. Before mounting a new
wheel, be sure the wheel
RPM rating is equal or higher than the
speed of the grinder.

3. Wheel Flanges: Only use the flanges

included with the grinder when
mounting wheels. Other flanges may
not properly secure the wheel and could
cause the wheel to fly off or break apart.

4. Ring Test: Perform a "ring test" on

grinding wheels before installation to
ensure that they are safe to use. A wheel
that does not pass the ring test may
break or fly apart during operation.

5. Starting Grinder: If a wheel IS damaged,

it will usually fly apart shortly after
start-up. To protect yourself, always
stand to the side of the grinder when
turning it ON and allow it to gain full
speed before standing in front of it.

7. Workpiece Contact: A heavy impact on a

grinding wheel can cause it to break or fly
apart, causing serious personal injuries.
Avoid jamming the workpiece into the
wheel to reduce this risk.

8. Hand/Wheel Contact: Grinding wheels

have the capability of removing a lot
of skin fast. Make sure the workpiece
is securely clamped to the table, then
position your hands a safe distance away
when grinding. Avoid wearing gloves as
they may get caught in the grinding wheel
and cause even more serious entanglement
injuries.

9. Cracked Wheel: Cracked wheels may break

and fly apart during operation. Replace
cracked wheels immediately!

10. Fire Hazard: DO NOT connect a surface

grinder to a dust collection system that is
used with woodworking machines. Sparks
emitted from the grinding process may
ignite wood particles, resulting in fire or
explosion. Only use a metal-specific dust
collection system with this machine.

6. Lung Protection: Grinding produces

hazardous dust, which may cause long­term respiratory problems if breathed.
Always wear a NIOSH approved dust
mask or respirator when grinding.

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.

GAS

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.

Avoid chlorine-based solvents, such as
acetone or brake parts cleaner that may
damage painted surfaces. Always follow the
manufacturer’s instructions when using any
type of cleaning product.

Weight Load

Refer to the Machine Specifications 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 workpiece that will be used.
Additionally, consider the weight of the operator
and any dynamic loading that may occur when
operating the machine.

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 maintenance and service
described in this manual.

Physical Environment

The physical environment where your machine
is operated is important for safe operation and
longevity of parts. For best results, operate this
machine in a dry environment that is free from
excessive moisture, hazardous or flammable
chemicals, airborne abrasives, or extreme
conditions. Extreme conditions for this type
of machinery are generally those where the
ambient temperature is outside the range of 41°–
104°F; the relative humidity is outside the range
of 20–95% (non-condensing); or the environment
is subject to vibration, shocks, or bumps.

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.

Lighting

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.

Children or untrained
people may be seriously
injured by this machine.
Only install in an access
restricted location.

Figure 4. Space required for full range of movement.

For Machines Mfg. Since 8 /09 Model SB1023

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.

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.

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.

PREPARATION

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.

Unbolt the machine from the pallet and make
sure that the table is locked in place. Connect a
chain or lifting strap to the lifting hook on the
machine (Figure 5), use a hoist or forklift to lift
the machine off the pallet, and move it to the
suitable location. All hoisting equipment and
straps must be rated to lift at lease 1500 lbs.

Leveling & Mounting

Leveling

Never attempt to move this machine without
first locking the table in place. If the machine

OPERATION

Wheel Selection

Most grinding wheels from major manufacturers
are marked in a somewhat uniform manner.
Understanding these markings will help you
understand the capabilities of various wheels.
Always refer to the manufacturer’s grinding
recommendations when selecting a wheel for
your project.

The grinding wheel you choose will depend on
several factors related to the operation you plan
to perform. The hardness of the material you
will be grinding and the surface finish you desire
are the two primary factors to consider when
selecting a grinding wheel.

An example of the basic format for wheel
numbering is shown below. The wheel in this
example is a "36A60LV".

Removing & Installing
Grinding Wheels

If you must conduct a ring test, the grinding
wheel must be removed and reinstalled onto the
hub. However, when doing this, remember that
overtightening or rotating the spanner nut in the
incorrect direction can damage threads, crack
the grinding wheel, and make grinding wheel
removal more difficult than necessary.

To remove and install a grinding wheel:

Note: If you need to replace or install new paper

washers, replacements can be cut out of
any thick construction paper or card stock.
Regular notebook paper or paper from a copy
machine is not acceptable, as it is too thin to
provide the required cushion. Don't forget to
record the wheel type and RPM rating on the
new paper washer.

10. Ring test the grinding wheel, even if it is
new, then if the wheel is free of cracks, slide

the wheel onto the hub. Refer to Ring Test
on Page 25 for details.

11. Complete the preceding steps in the reverse
order to install the grinding wheel.

• After the grinding wheel is installed, you

will have to use the dressing tool to true­up the wheel. Refer to Wheel Dressing
on Page 25 for details.

Figure 18. Wheel mounting hub.

9. Inspect the paper washers for missing pieces
on both sides of the grinding wheel (Figure

19). The paper washers are cushions
between the spacer washer and the grinding
wheel seat. Without the washers, cracks can
spawn from the center of the wheel when the
spanner nut is tightened. Over time, these
cracks can radiate outward and the wheel
may explode possibly causing injury.

• When the wheel runs true, the hub and
grinding wheel must then be removed
and balanced as an assembly since
grinding wheels can have different
densities at various points of the
wheel. The wheel will only deliver
superior results if it is properly trued­up and balanced. Refer to Removing

& Installing Wheel & Hub on Page
22 to remove the assembly; and refer

to Wheel Balancing on Page 26 for
specific procedures on balancing.

Removing & Installing
Wheel & Hub

When the wheel has been ring tested, and
dressed, the wheel and hub must be removed and
balanced as an assembly. However, remember
that overtightening or rotating the spindle bolt in
the incorrect direction can damage threads, crack
the grinding wheel, and make grinding wheel
removal more difficult than it needs to be.

When removing and installing the hub onto the
spindle or balancing arbor, keep in mind that the
mating surfaces between these components have
the single most important effect on your final
balancing results. Hubs, spindles, and balancing
arbors can be easily damaged during installation
and removal. Just one grain of sand, small burr,
or hidden ding in either mating surface will
undermine all balancing results. Make sure
that all mating surfaces are carefully stoned to
establish a perfect fit.

NEVER pound on a hub or arbor for any reason.
This will permanently displace metal and change
high tolerance dimensions.

To remove and reinstall the wheel and hub:

1. DISCONNECT MACHINE FROM POWER!

2. Place a sheet of plywood or similar on top of

table to protect the table (Figure 20), and
open the grinding wheel cover.

Figure 20. Protecting the table.

3. Position the spindle wrench on the spindle
bolt (Figure 21).

NEVER use a hydraulic press to install the
balancing arbor or attempt to use a heat
differential between parts to establish a shrink­fit. This will change high tolerance dimensions.

NEVER twist-fit the hub onto the spindle or
the balancing arbor. Doing this can gall the
tapered surfaces. Instead use a small arbor press
with light pressure to install and remove the
balancing arbor from the hub.

ALWAYS make sure that all mating surfaces
are immaculately cleaned before hub or arbor
installation. Use a lint-free photography lens
cloth that is slightly oiled with a thin machine
oil. For the best fit, the mating surfaces must
be polished without having a wet layer of oil on
them. The oil should only be in the pores of the
metal.

Wheel Inspection

Do not assume that a wheel is in sound condition
just because it is new—damage can often occur
during shipping, with age, with prolonged
exposure to moisture, or because of improper
storage.

To inspect a wheel for damage:

1. Remove the wheel and look for any cracks,
chips, nicks or dents in the surface of the
wheel. If you see any of these, DO NOT
attempt to use the wheel.

2. Do a ring test. This test will give you an
indication of any internal damage that may
not be obvious during a visual inspection.

3. Inspect the paper washers on both sides
of the grinding wheel (Figure 29). These
washers are cushions between the spacer
washer and the grinding wheel seat. Without
the washers, cracks can be spawned from
the center of the wheel when the spanner
nut is tightened. Over time, these cracks can
radiate outward and the wheel may explode
during operation, possibly causing injury.

12. To install the grinding wheel and hub,
complete the preceding steps in the reverse
order, but skipping the steps regarding hub
puller usage. After the grinding wheel and
hub are installed, many machinists still
choose to dress the grinding wheel. Refer to
Wheel Dressing on Page 25 for details.

Ring Test Wheel Dressing

This test will give you an indication of any
internal damage that may not be obvious during

a visual inspection.

To perform a ring test:

1. Make sure the wheel that you test is clean
and dry; otherwise, you may get false
results.

2. Hang the wheel in the air with a piece of
cord or string looped through the hole in the
center, as shown in Figure 30.

Superior grinding results can only be achieved
with a properly balanced and dressed wheel. Do
not assume that a wheel will run true on the
spindle if it is new or has not been separated
from the hub.

Dressing the wheel correctly will save you from
wasting grinding abrasive and shattering the
dressing tool diamond. Additionally, with a
properly balanced and dressed wheel you can
rest assured that if you have finish problems, the
grinding wheel is not the culprit.

Depending on the finish required, varying
degrees of roughness can be obtained. For
example: A fast dressing at a depth of 0.03mm
will prepare a wheel surface for rough cuts, and
slow dressing with multiple light passes of the
diamond at a depth of 0.01mm will prepare the
same wheel for finish cuts.

Positioning is critical for the dressing tool so
you will not shatter the diamond or have poor
dressing results. The dressing tool must be
positioned in the trailing zone of the wheel, as
shown in Figure 31, for best results and safe
use. If the tool is positioned on the leading side
of the wheel, the diamond will be shattered or
even grabbed by the wheel and drawn under the
grinding wheel, causing severe damage or injury.

Paper Washer

Figure 30. Ring test setup and test locations.

3. At the locations shown in Figure 30, gently
tap the wheel with a light non-metallic
device such as the handle of a screwdriver or
a wooden mallet.

An undamaged wheel will emit a clear

metallic ring or “ping” sound in each of these
spots. A damaged wheel will respond with
a dull thud that has no clear tone. If you
determine from the ring test that the wheel
is damaged, DO NOT use it!

To dress the grinding wheel:

1. Insert the diamond tipped dressing tool into
its base (Figure 32), and use a 4mm hex
wrench to tighten the locking set screw.

Figure 32. Dressing tool setup.

2. Lower the headstock so the wheel is
approximately 5mm lower than the tip of the
dressing tool.

Wheel Balancing

Static wheel balancing can be difficult and very
time consuming without practice. For accurate
grinding results, wheel balancing is mandatory.
For this balancing procedure, you will need a
wheel balancing fixture. The wheel balancing
fixture shown in Figure 33 is one example of the
many varieties available on the market.
Before proceeding, the grinding wheel must be
ring tested (refer to Page ) and dressed (refer to

Page ).

3. Position the tip of the dressing tool at the

trailing side of the wheel, as shown in
Figure 31, and move the table inward until
the diamond tip of the dressing tool slightly
touches the edge of the grinding wheel.
Verify by manually rotating the wheel and
listening for contact.

4. Turn on the magnetic chuck, and move the
cross slide so the tip is free of the grinding
wheel.

5. Start the grinder, and use the cross slide
handwheel to progressively move the table,
so the diamond sweeps across the wheel at a
depth between 0.01 – 0.03mm.

Figure 33. Wheel on balancing fixture.

If flood coolant was used with the grinding
wheel, run the machine with the grinding wheel
installed for 5-minutes to sling off any residual
coolant that may have settled to the low side of
the wheel. If the paper washers are missing, wet,
or damaged, replace them before proceeding. If
during a period of machine operation, you find
that a finish is becoming poor, redress the wheel.
If that does not correct the problem rebalance
your grinding wheel.

To balance the grinding wheel:

1. DISCONNECT MACHINE FROM POWER!

2. Set up the wheel balancer as outlined in its

product user manual.

3. Remove the grinding wheel and hub as
a unit from the spindle as outlined in

4. Without letting any of the dogs or the lock

balls they contain fall out of the hub, use
a 2.5mm hex wrench to loosen the dogs
and position them at the 0°, 120°, and 240°
degree locations as indicated by the degree
scale on the hub (Figure 34).

Note: Pay special attention to keep the dogs

engaged in the hub slot when they are loose.
If you lose any of the 4mm lock balls, it will
be impossible to continue this procedure
until they are replaced.

5. Using a slightly-oiled lint free cloth, wipe the
mating surfaces of the balancing arbor and
the internal hub taper perfectly clean, and
push the hub and arbor together, as shown
in Figure 35.

7. Spin the wheel so it rotates one full turn and
comes to rest with the heaviest side hanging
down at six o'clock. This may take a few
times to find the exact location.

8. Using a pencil, draw a line at the six o'clock
position to mark the heaviest side of the
wheel.

9. Line up the closest dog with the line you
just drew and lock it in place. This dog will
now be positioned at the heaviest side of the
wheel and will be called dog "A".

10. Using the scale, position the other two "B"
dogs so they are both evenly spaced 120°
degrees apart from dog "A". At this point all
dogs will be 120° apart from one another.
The "B" dogs are the two dogs you will move
to balance the wheel.

11. Rotate the wheel 90° degrees, let go, and
observe the direction that it rotates out of
balance. Move each "B" dog in one degree
increments, toward each other and away
from dog "A" to balance the wheel. For
example, depending on the amount of
balance correction, the distance between
the two "B" dogs will decrease, and the
distance between the "B" dogs and "A" dog
will increase. This step must be repeated
as many times as required until the wheel
will not rock back and forth by itself in any
position.

Figure 35. Installing the balancing arbor.

6. Place the balancing arbor onto the wheel
balancing fixture (Figure 33).

12. When you are satisfied with the wheel
balance, install the grinding wheel on the
machine, and run it for five minutes to verify
the wheel is in balance.

13. If any balance problems are detected, repeat
the balancing procedure.

Note: Some machinists will re-dress the grinding

wheel one last time at this point to ensure
ultra-high grinding precision.

Magnetic Chuck

The Model SB1023 is designed to be used with
a magnetic chuck. The table is equipped with a
T-slot for securing your magnetic chuck. Refer to
your magnetic chuck manufacturer's instruction
manual for proper chuck preparation and
mounting techniques.

A magnetic chuck secures workpieces to the table
without the use of clamps. With proper attention
to preparation of both the workpiece and the
magnetic chuck, a magnetic chuck will provide
ample clamping force on most magnetic metals.
Refer to your magnetic chuck manufacturer's
instruction manual for proper workpiece
mounting techniques.

Setup for a Typical
Grinding Operation

Grinder Operation

Grinding with a surface grinder is a delicate
process that takes practice, skill, and knowledge.
In addition to this, the method used for any one
procedure will depend on a number of factors,
including, but not limited to the material being
ground, the grinding wheel being used, the
quality and calibration of measuring tools, and
the finish that is desired.

For these reasons, specific techniques are not
outlined in this manual. We recommend that you
consult books, trade magazines, metalworking
experts, and other reliable resources for
techniques pertaining to the specific tasks you
wish to perform.

The information that follows serves as a general
outline to help familiarize you with the basic
grinding technique.

Once you have chosen the proper wheel for the
operation and properly installed the magnetic
chuck on the table, use the following procedures
to prepare for a grinding operation.

To prepare for a grinding operation:

1. DISCONNECT MACHINE FROM POWER!

2. To ensure flat mating surfaces on the

workpiece and the magnetic chuck, surface
grind and stone the top of the chuck and the
bottom of the workpiece.

3. Make sure the magnetic chuck is turned
OFF, then place the workpiece onto the
chuck. Once the workpiece is positioned as
needed, turn the magnetic chuck ON.

4. Make sure the grinding wheel is not
contacting the workpiece, connect the
grinder to power, then turn the motor ON.

OPERATION

Using the Surface Grinder

Operation of the grinder is controlled through
the movement of the three handwheels. The
elevation handwheel controls the up and down
movement of the grinding head. It is this axis
that governs the amount of stock removal.
Never attempt to remove too much material in
one pass. The best results are be achieved with
multiple light passes.

The longitudinal travel handwheel rapidly moves
the table from left to right. This allows the
operator to move the workpiece back and forth
underneath the grinding wheel.

The cross travel handwheel controls the front­to-back movement of the table and is only to be
used between longitudinal passes to expose a
new area of the workpiece to the grinding wheel

When grinding, sweep the table back and forth
under the wheel in the longitudinal direction
until no further sparks emerge from the
workpiece, move the table in the cross direction
to expose a new portion of the workpiece to
the wheel, then take another sweep in the
longitudinal direction. Repeat this process until
the entire surface is ground. See Figure 36 for
an illustration of this process.

Grinding Tips

While every grinding operation is unique, there
are a few techniques that apply to most, if not all
grinding operations.

• Duringlongitudinalpasses,tightenthecross

travel lock knob to prevent chatter that may
occur as a result of slight cross movement of
the table.

• Betweenlongitudinalpasses,usethe

squeegee to remove any foreign material
from the workpiece.

Handwheel Backlash
Adjustment

Backlash is the amount of play found in a
leadscrew. Without moving the table, the amount
of backlash can be determined by lightly turning
the handwheel with your fingertips in one
direction until the handwheel stops, noting the
location shown on the handwheel scale. Then the
handwheel is turned in the other direction until
it stops. The distance between both stopping
locations is the amount of backlash. If the
backlash exceeds 0.007", adjust it back into range
the of 0.003" to 0.006".

The backlash adjustment is made by tightening
or loosening the cross-feed leadscrew halfnut
cap screws shown in Figure 42. These screws
draw two halves of the halfnut together against
the leadscrew placing pressure on the threads.
If this fit is too tight, loosen the cap screws, tap
the table a few times with a rubber or wooden
mallet, and turn the handle slowly back-and­forth until the handle turns freely. To readjust
the backlash, rock the handle back-and-forth and
tighten the screws slowly until the backlash is
correct.

Column & Table Gib
Adjustment

The gib is a tapered piece of steel that is held in
position by a gib screw. When the screw is turned
clockwise, the gib will be moved to fill the loose
void in the way, thus, removing the play. If more
play is needed, adjust the screws the opposite
direction.

When adjusting the table or column gib screw
(Figure 43), keep in mind that the goal is to
remove sloppiness in the ways without causing
the dovetailed ways to bind or prematurely wear.
A loose gib can cause dimensional problems or a
poor finish on the workpiece.

Note: Avoid the temptation to overtighten

the cap screws at the leadscrew halfnut.
Overtightening will cause excessive wear
to the halfnut and leadscrew. Reducing
backlash to less than 0.003" is impractical
and reduces the life of the gib and the ways.

Service

Machine Storage

Never attempt to move this machine without
first locking the table in place. If the machine
is slightly tilted, the table could uncontrollably
slide and fall off of the machine and cause
machine damage or severe injury.

Machinery can develop serious rust problems and
corrosion damage if it is not properly prepared
for storage. If decommissioning this machine, use
the steps in this section to ensure that it remains
in good condition.

Short-term storage (less than
year)

1. DISCONNECT MACHINE FROM POWER!

2. Thoroughly clean all unpainted, bare

metal surfaces, then coat them with a rust
preventative oil or wax specifically designed
to protect machinery while in storage. DO
NOT USE MOTOR OIL in storage situations
as it does not sufficiently protect against
rust.

3. Lubricate the machine as outlined in the
Lubrication section on Page 30.

4. Cover and place the machine in an area

that is out of direct sunlight and away
from where paints and thinners are stored,
or where gasses are present. Fumes and
sunlight can bleach or discolor paint and
clear plastic guards.

5. Once or twice a month, depending on
humidity, wipe down the machine as
outlined in Step 2.

Long-term storage

Long-term storage (more than a
year)

1. Empty and flush any cutting fluid pumps,
lines, or tanks.

2. DISCONNECT MACHINE FROM POWER!

3. Thoroughly clean all unpainted, bare metal

surfaces, then coat them with a heavy grease
or rust preventative. Take care to ensure
these surfaces are completely covered but
that the grease or rust preventative is kept
off painted surfaces. Make sure that both
the upper and lower portions of the column
leadscrew are completely coated with white
lithium grease.

4. Remove the table, and then clean and pack
the bearings with white lithium grease.

5. Using mineral spirits, clean and brush the
ways, rack, pinion gear, and the leadscrew
with any quality grease or wax that is
specifically formulated for protecting
machine parts during storage.

6. Open the main electrical box on the machine
and place a few moisture absorbing desiccant
packs at the bottom of the electrical box.

7. Cover and place the machine in an area
that is out of direct sunlight and away
from where paints and thinners are stored,
or where gasses are present. Fumes and
sunlight can bleach or discolor paint and
clear plastic guards.

Note: When the machine is being put back into

service from long-term storage, lubricate
the machine as outlined in the Lubrication
section on Page 30.

6. Every two months, move all handwheels so
the headstock and column move at least once
in their full range of motion. This will keep
the bearings, bushings, gears, and shafts
well lubricated and protected from corrosion,
especially during the winter months.
