Introduction
This manual includes the operating and maintenance instructions for the Wilton 12-inch Universal
Tilt Frame Vertical Cut-Off Band Saw, Models
VTF6-2 and VTF6-4. This manual also includes
parts listings and illustrations of replaceable parts for
the band saw.
Tilt-Frame Saw Features
Refer to Figure 1 for key features of the Model
VTF6 tilt-frame band saw. The tilt-frame band saw is
designed to cut stock at various angles by tilting the
saw frame to the desired angle. When tilted to the
right, the saw can cut at angles up to 60 degrees.
When tilted to the left, the saw can cut at angles up
to 45 degrees.
The machine consists of a base weldment onto
which is installed all other machine components.
Major components include the base, the saw head,
the rocker mechanism, the hydraulic system, the
coolant system, the vise, and the machine operating
controls and indicators.
The saw frame is supported by guide rails mounted on
the rocker mechanism. When cutting a length of
stock, the saw frame translates from the back to the
front on the guide rails. The back to front movement
is accomplished by an hydraulic cylinder.
The saw has a vise on the left side of the work table.
The vise is opened and closed using a hand wheel
on the left front of the machine. The front
(moveable) jaw is supported by and moves using an
Acme screw. The vise has extra large, steel jaws
that provide for clamping of various sizes and
shapes of material.
Electrical Enclosure
The electrical enclosure is located at the right front
of the cut-off saw. The enclosure contains the
electrical components required to operate the saw.
(Refer to the Electrical Connection section.)
The operator's control panel is mounted to the top of
the electrical enclosure. (Refer to the Operating
Controls section for further description.)
Saw Head
The saw frame is mounted on a rocker mechanism
which, in turn, is supported by pillow blocks. A disk
attached to the forward pillow block has a cutting
angle indicator.
The saw head consists of a drive motor, a speed
reduction gearbox, drive and driven blade wheels,
saw blade guide bearings and a saw blade. Blade
guards are provided to cover the exposed areas of
the saw blade.
The rocker mechanism, and therefore the tilt angle,
is changed by an hydraulic cylinder mounted at the
rear of the machine.
Access to the saw blade is gained through the blade
wheel doors. The upper door is accessed from the
left side of the machine. The lower door is accessed

Saw Frame Guiderails and Hydraulic Cylinder (under cover)
from underneath the machine worktable. The covers
are fitted with limit switches that serve as system
safeties to prevent accidental motor start up during
maintenance or blade replacement.
The saw blade is driven by the motor driven blade
wheel and is supported by adjustable blade guides.
Blade tracking adjustment screws are provided in
the tensioning mechanism in the saw frame, providing a means to keep the blade tracking evenly on
the blade wheels.
A blade tension indicator is provided on the tension
drum assembly. When correctly tensioned, a tab in
the slot of the tension drum housing is aligned with a
line scribed into the constant tension housing.
Three blade tracking adjustment screws and jam
nuts are provided on the blade tensioning mechanism. The adjusting screws are used to change the
tilt of the drive wheel as needed to ensure the blade
tracks properly.
Blade Guides
The blade guide assemblies provide support for the
saw blade to assure squareness and accuracy of the
cut. Two blade guide assemblies are provided. The
upper blade guide is located on an adjustable
support in the saw frame. The lower blade guide
assembly is mounted on a bracket just above the
lower drive wheel.
When in use, the saw blade is twisted 90 degrees by
the blade guides bearings and tungsten inserts. The
blade is twisted to position the blade's cutting teeth
toward the workpiece.
The blade guides consist of five blade-side bearings, a blade back-edge bearing, and two tungsten
inserts. The side bearings assure that the saw blade
is perpendicular to the cutting piece. The back-edge
bearing assures that the blade is not deflected
rearward when the blade begins to feed into the
cutting piece. The adjustable carbide inserts provide
lateral support for the blade.
A coolant hose fitting is provided on the blade
guides to provide coolant flow directly onto the saw
blade/workpiece interface.
Blade Tensioning Mechanism
A blade tensioning mechanism (refer to Figure 7)
provides a means to set the tension of the saw
blade. Blade tension is adjusted using a handle on
the mechanism.
Coolant System
The saw has a coolant system to provide coolant
flow to the workpiece. The coolant reservoir is
located underneath the machine. The coolant pump/
motor is mounted on a plate on the top of the
coolant reservoir.
Hydraulic System
The hydraulic system (refer to the Hydraulic
System Components illustration in the Replacement Parts section) provides the hydraulic pressure
required to operate the hydraulic cylinders that, 1)
tilt the frame, 2) clamp and hold the rocker mechanism in position, 3) move the saw frame forward and
rearward, and 4) control the feed rate.
The hydraulic pump and valves are mounted on the
top of the hydraulic reservoir. The hydraulic reservoir is located under a cover at the rear of the
machine.
The fluid level can be seen through an opening at
the left rear of the machine (see Figure 5). The
valve manifold is fitted with a hydraulic system filter.
A filler cap on the top of the tank is used to fill or
replenish the reservoir with hydraulic fluid.
Setup and Operation
Before operating the machine, setup the machine
and perform post-installation checks as defined in
the following paragraphs.
Machine Setup
The saw has been adjusted at the factory. A number
of test pieces have been cut using the saw to verify
the accuracy of cutting. Therefore, the only setup
operations required before releasing the saw for
service are placing and securing the saw, and
establishing the electrical connections to the motor.
(Refer to the Electrical Connection section for
wiring requirements.)
Use a fork lift to move the machine to the installation site (see Figure 2). Place the saw where it
makes the most sense for the operations you will
probably be doing. If you are going to be doing cutoff work on very long stock, allow plenty of room for
the length of the stock; provide infeed and outfeed
supports
as required.
.
Remove the saw from the shipping skid and discard
any hold-down devices that were used to secure the
saw to the skid. Level the machine and anchor it to
the floor using the holes in the feet of the machine
base.

13. After connecting electrical power, verify that
hydraulic pump runs in the correct direction
(observe direction of arrow on motor). This is
absolutely necessary for the pump to build up
hydraulic pressure.
Electrical Connection
Observe the following when connecting to facility
power. (See Wiring Diagrams section.)
WARNING: WILTON RECOMMENDS THAT ANY
HARD WIRING OF THE SAW TO FACILITY
POWER OR ANY CHANGE IN VOLTAGE SUPPLIED TO THE MOTOR BE PERFORMED BY A

3. Make sure the machine frame is not distorted
when fastened to the floor.
4. It is suggested that the floor surface be treated to
prevent coolant or hydraulic oil from being
absorbed.
5. Provide sufficient clearance between adjacent
walls and machines to allow handling of the
length of stock expected to be cut.
6. Level the machine worktable using a precision
level.
7. The operating environment for the machine
should have an ambient temperature between
32° and 95° Fahrenheit (0° and 35° Celsius).
8. The handle of the vise handwheel is installed
facing inward for transport. Make sure the
handle is placed in the correct position before
starting the machine.
9. Remove all shipping materials used for protection of the machine during shipping.
10. Mount all loose accessories to the machine
before startup.
11. Insert coolant reservoir under the bottom of the
machine. Mount coolant pump and pump cover.
12. Check direction of saw blade. The teeth should
be positioned so they teeth are facing downward
as it passes through the blade guides.
1. Make sure the saw is disconnected from facility
power. Make sure fuses have been removed or
make sure breakers are tripped in the circuit to
which the saw will be connected. Make sure you
put a warning placard on the fuse holder or circuit
breaker to prevent accidental electrical shock.
2. If you are using hard-wired connections to a
junction box, connect the wires in the box, and
close the box.
3. Install the fuses or reset the breakers.
4. The saw is now ready for service.
Operating Instructions
CAUTION: Remove all saw frame shipping
materials before operating the machine for the
first time.
Complete the following steps at first saw startup:
• Set angle indicator reference and adjust for
desired cutting angle.

Adjustments
The efficient operation of the cut-off saw is dependent upon the condition of the saw blade. If the
performance of the saw begins to deteriorate, the
first item that you should check is the blade.
If a new blade does not restore the machine’s
cutting accuracy and quality, refer to the Troubleshooting section (or the blade manufacturer’s
guide) for conditions to consider and adjustments
that can be made to increase the life of the blade.
To change the blade, refer to Replacing Blades in
the Maintenance section. To adjust the blade
tracking, refer to the following procedures.
Figure 6. Adjustment of Blade Guide Support
Adjusting Blade Guide Inserts
The blade guide inserts installed in the blade guide
assemblies are subject to wear and will periodically
require adjustment. Adjust the blade guide inserts as
follows:
Note: The item references in the following
procedures correspond to the item numbers in the
corresponding exploded view for the blade guide
assembly in the Replacement Parts section.
1. Loosen the two screws (14) securing inserts
(3). The inserts can be moved laterally as
needed.
2. Move one of the inserts (3) until it contacts the
side of the saw blade. Do not deflect the blade.
Tighten the corresponding screw (14).
3.
Move the other insert (3) into contact with the
blade. Hold the inserts in that position while
tightening the second screw (14).
Place the stock between the vise jaws and clamp
tightly. Observe the recommendations for clamping
workpieces of different shapes (see Figure 9.)
Blade Tensioning Adjustment
Vise Jaws
When changing the saw blade or when replacing
blade drive components, it will be necessary to
adjust the tension on the saw blade. Blade tension is
adjusted using the handwheel at the top of the saw
frame. Turning the handwheel clockwise tightens the
blade. Turning the handwheel counterclockwise
reduces blade tension.
The blade tension mechanism has a visual indicator
of blade tension. The blade should be tightened until
the tab on the indicator is aligned with the scribe
mark on the tension assembly (see Figure 7).
Blade Tracking Adjustment
Blade tracking has been tested at the factory.
Adjustment is rarely required when the blade is used
properly or if the blade is correctly welded. (See
Figure 7 for location of blade tracking adjustment
screws.)

5. Be prepared to adjust the threaded adjustment
pins in the blade tensioning mechanism (see
Figure 7).
CAUTION: WHILE PERFORMING THE FOLLOWING, KEEP THE BLADE FROM RUBBING EXCESSIVELY ON THE SHOULDER OF THE WHEEL.
EXCESSIVE RUBBING WILL DAMAGE THE
WHEEL AND/OR THE BLADE.
6. Start the saw. Slowly turn the two adjustment
pins at the rear of the tracking mechanism to tilt
the idler wheel. Do not turn the other two
adjustment pins. Alternately turn the adjustment
pins in small increments until the blade is
touching the shoulder of the idler wheel.
7. Alternately turn the adjustment pins in small
increments so the blade starts to move away
from the shoulder of the wheel — then immediately turn the adjustment pins in the other
direction so the blade stops moving across the
wheel, then moves slowly toward the shoulder.
WARNING: KEEP FINGERS CLEAR OF THE
BLADE AND WHEEL TO AVOID INJURY.
12
8. Turn the adjustment pins to stop the motion of
the blade on the wheel as it gets closer to the
wheel shoulder. Put a 6-inch length of paper
between the blade and the wheel as shown in
Figure 10. The paper should not be cut as it
passes between the wheel shoulder and blade.
NOTE: Turning the screw inward causes the blade
to move toward the shoulder of the wheel. Turning
the screw outward causes the blade to move away
from the shoulder.
9. Turn the adjustment pins a small amount. Repeat
the insertion of the paper between the wheel
shoulder and the blade until the paper is cut in
two pieces.
NOTE: You may have to repeat the check with the
paper several times before the blade and the
shoulder cuts the paper into two pieces. Do not
hurry the adjustment. Patience and accuracy here
will pay off with better, more accurate, quieter
cutting and much longer machine and blade life.
10. When the paper is cut, turn the hex adjustment
screw slightly in the counterclockwise direction.
This assures that the blade is not touching the
shoulder of the wheel.
11. Shut off the saw.
12. Hold the hex adjustment screws with a wrench
and tighten the jam nuts. Make sure the hex
adjustment screws do not move while tightening
the lock nuts.
13. Close the saw head cover.
Verifying Cutting Accuracy
Test cuts can be used to determine whether or not
you have adjusted the blade accurately. Use 2-inch
round bar stock to perform these test cuts, as
follows:
1. With the bar stock securely clamped in the vise,
make a cut through the bar stock (see Figure
11.)
2. Mark the top of the bar stock.
3. Move the bar stock about 1/4-inch past the blade
so you can begin a second cut.
4. Rotate the bar stock 180 degrees so the mark
you made is now at the bottom of the cut.
5. Make a cut through the bar stock.
6. Use a micrometer to measure the thickness
variation of the disk you have cut from the bar
stock. Measure at the top and bottom of the
disk.
7. The saw blade can be considered correctly
adjusted when the variation is no more than
0.012 inch across the face of the disk.
If you do not have a piece of 2-inch bar stock
available for a test cut, use a larger diameter test
piece rather than a smaller one. The maximum
thickness variation on any test piece should be no
more than 0.003 inch per side, per inch of stock
diameter.
Band Saw Operation
Before switching on the saw motor, make the
following adjustments:
• Use a saw blade with adequate tooth spacing
• Adjust blade speed and feed rate.

Tips for Optimum Sawing
Saw Blade Teeth Breakage
Each tooth of the saw blade can only withstand a
defined cutting force which varies depending on
blade quality. If this limit is exceeded, the tooth will
break.
5. Measure
here . . .
New slice
VERIFY THAT THE SAW BLADE IS NOT
TOUCHING THE MATERIAL BEFORE STARTING THE DRIVE MOTOR. THE BLADE CAN
BE DAMAGED IF THE BLADE IS IN CONTACT
WITH THE MATERIAL.
NEVER USE DULL SAW BLADES. USE OF
DULL BLADES WILL PRODUCE POOR AND
INACCURATE CUTTING.
IF THE CUTTING OPERATION IS INTERRUPTED
BECAUSE OF SAW BLADE TOOTH BREAKAGE, DO NOT CONTINUE CUTTING IN THE
SAME CUTTING CHANNEL WITH A NEW SAW
BLADE. THE NEW BLADE COULD BE DAMAGED BY THE REMNANTS OF THE BROKEN
TOOTH. REMOVE ANY BROKEN TEETH STILL
IN THE CHANNEL.
NEVER MOVE THE SAW BLADE ABRUPTLY
INTO THE MATERIAL. DOING SO WILL
REDUCE THE SERVICE LIFE OF SAW
BLADE.
IF THE SAWING OPERATION WAS INTERRUPTED, RETURN THE SAW FRAME TO
THE BACK OF THE MACHINE BEFORE
CONTINUING THE SAWING OPERATION.
ALWAYS PERFORM A RUN-IN ON NEW SAW
BLADES. DOING SO WILL INCREASE
SERVICE LIFE OF SAW BLADE.
NEVER USE DULL SAW BLADES. USE OF
DULL BLADES WILL PRODUCE POOR AND
INACCURATE CUTTING.
Cutting pressure (modify only in special cases
such as high-alloy steel).
Miter (saw frame) angle
Positioning of material and clamping of vise
Adjustment of upper blade guide distance from
workpiece/stock.
Provide for removal of cuttings
Overcharging of chip space happens when larger
cross sections are sawn with fine-spaced saw
blades (such as cutting a 4-inch diameter workpiece
with a 10 Z/inch saw blade) and high feed rates.
In some cases, fine-spaced saw blades can be used
to saw larger cross sections. However, a lower feed
rate must be used.
Breaking of Teeth Results from:
•
•
Sawing thin wall profiles with a blade that has
tooth spacing that is too large or by using feed
rate that is too high.
Feed rate too fast or saw blade touching
material before starting saw motor.
13
Saw Blade Life
The saw blade can become prematurely dull if you
do not match the blade to the material, if you select
too high a cutting speed, or if you do not use any
coolant. If the cutting speed is too high, the saw
blade teeth will become dull due to overheating.
Overheating the tips of the teeth can also occur
when the saw blade slides across the workpiece
with little or no chip removal (results in poor heat
transfer because only the tooth tips contact the
material).
Feed Rate for Changing Profiles
When sawing profiles such as tubes, the cross
section being cut changes continuously as the blade
cuts through the tube. Initially it is like a piece of
solid round stock. When it breaks through the wall
of the tube, the blade is contacting the two sides of
the tube. For sawing operations involving changing
profiles, we recommend using multiple pitch blades.
The feed rate used on changing profiles should not
be made too fast. The rate should be even lower
with differing cross section profiles in order to avoid
tooth breakage.
• In some cases, however, it might be less expensive
to use saw blades of special quality. This applies if
constant tooth breakage is a problem.
• In order to take advantage of full machine capabilities, such as when sawing larger quantities of
the same materials and cross sections, select the
optimum spacing, shape of tooth and highest
quality saw blade possible.
• If you are not sure which saw blade to use for a
particular application, contact your dealer for help.
Tooth Profile
Standard Tooth (N) Effective cutting angle is zero
(0) degrees. Suitable for sawing
most types of cast iron and
steel.
Claw Tooth (K)
Effective cutting angle 10
degrees. Suitable for free
machining materials, such as
non-ferrous metals or low
strength steels.
Multiple Pitch (C) Variable spacing with different
shapes and depths of teeth.
Available only in bimetal. Suitable
for all materials and frequently
changing cross sections/profiles.
Flat Iron
Most tooth breakage occurs when cutting flat iron,
often from spacing that is too fine. By clamping flat
iron a bit diagonally, you can saw with fine spacing
because the cross section is reduced by the diagonal position of the flat iron.
Saw Blade Selection
14
Selection of the correct saw blade for various
materials is very important. Following are some tips
for determining the saw blade to use:
• Refer to the upper chart in Figure 12. When
cutting many different kinds of materials and
cross sections, we recommend using saw blades
with spacing of 4 Z/inches (shape of tooth N) and
spacing of 8/12 Z/inches (multiple pitch spacing).
• Saw blades with 4 Z/inches can be used for solid
material of 0.75 inch to 8.00 inches and profile
bars from 0.25 inch and higher. Multiple pitch
spacing of 8/12 Z/inches is used for solid material of 0.08 inch to 6.00 inches and profile bars
from 0.5 inch to 2.0 inches.
• As a rule, we recommend the use of high quality
bimetal saw blades so that all materials mentioned can be sawn (in particular, if there are
hardened blow holes) and fewer saw blade
replacements will be required.

(see Adjusting Blade Guide Inserts).
Every 1,000 Hours
1. Lubricate linear guide rails (see Lubricating
Linear Guide Rails).
2. Clean entire machine and dispose of chips and
saw debris. Remove debris from the drive, the
saw blade, the guide rails, and from the coolant
reservoir. (Take special care that linear guides of
the saw frame are cleaned of debris and dirt
every time the blade is replaced.)
3. Dispose of dust and coolant separately.
4. Verify that all adhesive labels are legible. If not,
replace the labels immediately.
5. Protect electrical components such as motors,
switches, and switch cabinet components, from
moisture during cleaning.
WARNING: NEVER USE FLAMMABLE SOLVENTS OR CLEANING AGENTS THAT COULD
EMIT DANGEROUS VAPORS.
Lubricating Linear Guide Rails
Every 1000 hours, apply a thin coating of general
purpose grease to upper and lower rails and the
corresponding guide blocks.
Hydraulic Oil Level
Check hydraulic oil level daily (see Figure 4). The
hydraulic oil level should be a minimum of 3/4 full.
Coolant Level
Check the coolant level daily. The coolant level
should be a minimum of 1/3 full.

Replacing Saw Blade
WARNING: ALWAYS WEAR LEATHER GLOVES
WHEN HANDLING SAW BLADE TO AVOID
INJURY FROM THE SAW TEETH.
Saw blade replacement is one of the most dangerous procedures performed on the band saw, since
the sharp teeth of the saw blade are completely
unprotected. This work must be completed by
authorized and trained personnel only.
Use the following procedure for saw blade replacement:
1. Switch off band saw motor and move saw frame
into rearmost position.
2. Put saw frame in right tilt of 7 to 7-1/2 degrees
to the right.
WARNING: ALWAYS TURN OFF MAIN POWER
SUPPLY TO THE MACHINE AND WEAR WORK
GLOVES WHEN REPLACING THE SAW BLADE.
16
3. Disconnect main power switch.
4. Loosen upper blade guide support locking
handle. Push support down until saw blade
cover can be tilted forward.
5. Open upper and lower blade wheel covers.
6. Loosen saw blade tensioner as far as possible.
7. Loosen chip brush locking screw (10). Turn chip
brush completely to the right.
8. Push saw blade forward out of the guides with
one hand and hold the blade with the other hand
so that blade does not engage (see Figure 13).
9. Remove saw blade from the machine. Hold saw
blade firmly with both hands.
10. Hold saw blade (see Figure 14) with both
hands. Wind the blade into a roll and fasten with
a length of wire.
11. Clean debris from the saw blade guides and the
linear guides.
12. Check condition of chip brush. Adjust or replace
if necessary.
Figure 14. Holding Saw Blade
Installation of Saw Blade
WARNING: HOLD SAW BLADE FIRMLY WITH
BOTH HANDS AND NEVER RELEASE THE
BLADE DURING INSTALLATION!
1. Hold the saw blade away from your body and feed
it slowly into place.
2. Check saw blade teeth direction. Teeth must
face the same direction the saw blade will run. If
not, change teeth direction by “twisting” the saw
blade.
3. To reverse the direction of the teeth, grasp the
upper third of saw blade tightly between thumbs
and forefingers of both hands, with thumb at the
outside of the saw blade. Then twist saw blade
by turning both hands in the same direction.
4. Insert saw blade into the saw.
5. Move it onto the drive wheel, then push it
upwards from below into the saw frame and
move it onto the idler wheel. Now push the saw
blade into the lower guide, and then into the
upper guide. The saw blade will have to be
turned 90 degrees.
CAUTION: THE BACK OF BLADE (NOT THE
TEETH) MUST BE BELOW THE STOP COLLAR
OF THE TENSIONING AND DRIVE ROLL. TEETH
MUST FACE FORWARD BETWEEN THE GUIDES!
Figure 17. Removing Saw Blade
6. Tighten saw blade slightly using the tension
handwheel and check seating of saw blade. If
necessary, correct seating of saw blade by
pressing against stop collar and pushing the
blade into the guides.
7. Put the chip brush back into its original position
and tighten screw (10).
8. Turn the tension handwheel until proper tension
is achieved. Use of a blade tensioning gauge is
recommended.
9. Close idler and drive wheel covers.
10. Adjust position of guide support and tighten the
locking handle.
NOTE: Each new saw blade should be run-in by
reducing the feed rate to 2/3 for the first 300 cm².

(dulling other teeth)
Coolant not being used
Cutting speed too high
Broken tooth
Saw blade gullet filled with debris
Select blade with correct ratio
Adjust coolant flow/use correct
coolant for material being used
Reduce speed
Use saw blade with a different
tooth ratio, or reduce feed rate,
or use a different clamping
method (especially with flat
steel)
.
Troubleshooting (Continued)
