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.

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.

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 is slightly tilted, the table could uncontrollably slide, fall off of the machine and cause machine damage or severe injury.

PREPARATION
Assembly
After the machine is placed in the final location, and before the lifting apparatus is removed, you should install the machine feet. Included with your machine are four cushioned feet with built-in adjustment studs (see Figure 7). These feet are easily installed and provide for accurate machine leveling.
To install the feet:
For Machines Mfg. Since 8 /09
8. Use a 19mm wrench to tighten the jam nuts inside of the cabinet and lock the feet studs into place.
Note: Over the course of the next six months,
periodically verify that the machine is still level, and re-adjust the feet as required.
9. Rotate the top handwheel counterclockwise to raise the headstock slightly. Then remove the wood support block (see Figure 8).
1. Using lifting equipment and wooden blocks, raise and support the machine base so there is approximately 5" between the floor and underside of the base.
2. Remove the jam nuts from the foot studs.
3. Apply any general-purpose automotive
grease to the stud threads.
4. Thread the studs into the machine base from the bottom up until the studs emerge from the cabinet floor approximately 2" (see Figure 7).

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".

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.
Spindle Taper

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
Removing & Installing Grinding Wheel Hub on Page 22.

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.

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.

MAINTENANCE
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.
