Notes on Sawing
It is widely recognized that a proficient operator is a
key to optimum bandsawing. He makes certain the
machine is properly maintained and adjusted for
dependable operation. He carefully sets up each
cutting job to prevent damage to the machine and
obtain the best performance from the equipment.
Experienced blade dealers can be very helpful in
selecting the grade and proper tooth blade for each
sawing job. All blades should be straight, have sharp
teeth with uniform set, and be “broken in” at a
reduced feed rate to obtain good cutting performance
and blade life.
Every cutting situation has special characteristics
requiring some experimentation to determine which
blade, speed and feed rate will achieve the most
satisfactory result. Cutting charts indicate a good
starting point, but must be modified by direct
experience if optimum performance is desired.
Here are some helpful pointers for adjusting speed
and feed for good cutting performance.
1. Make sure the saw is cutting a good chip from the
workpiece.
2. Watch for blue chips or excessive “smoke”
indicating heat in the cut which could damage the blade
or work harden the material being cut
3. Watch for excessive vibration or chatter marks on
the cut-off piece indicating possible damage to the saw
teeth by “hammering”.
4. Check the cut-off piece for flatness. A dull blade
or excessive feed will produce a “belly” in the cut.
5. Inspect the blade for worn, rounded or shiny cutting
edges. Avoid force cutting which will allow chips to
“weld” to saw teeth and eventually cause the teeth to be
stripped off the blade.
6. When experimenting, start with a slow speed and
feed rate. Gradually increase blade speed and then
feed pressure by small amounts until adverse effects
are noted. You can then set the speed and feed at a
reasonable level for continuous cutting. Remember
that blade speed and feed pressure must be balanced
to keep cutting a good chip.
Trouble Shooting
Premature Dulling of Blade Teeth
1. Feed rate too high or low. Check pages 36-37.
2. Blade speed too slow or too fast.
3. Faulty material; heavy scale, hard spots, etc.
4. Verify type of material.
5. If coolant flow is not covering saw teeth,
increase coolant flow rate.
6. If saw is vibrating in cut, reduce blade speed or
increase feed rate.
7. Chipped or broken tooth may be lodged in cut.
8. “Chip welding” caused by improper feed and
speed.
9. Incorrect coolant mixture.
10. Incorrect blade selection
11. Improper break-in of new blade. New blades
should be run initially with reduced feed pressure
for approximately 50 to100 square inches.
12. Saw blade teeth may be hitting blade guides.
Check for proper blade size.
Saw Blade Vibration
1. Incorrect blade speed for material.
2. Blade tension insufficient.
3. Back-up bearing may be worn.
4. Incorrect choice of saw tooth pitch.
5. Incorrect coolant mixture.
6. Incorrect feed setting. Increase feed.
7. Workpiece not firmly clamped in vice.
8. Worn or improperly adjusted saw guides. Check
and make necessary adjustments.
Blade Teeth Chipping or Ripping Out
1. Blade pitch too coarse. Use a fine pitch saw blade
on thin work sections.
2. Improper break-in of new blade. Do not start a
new blade in an old cut.
3. Work piece not held firmly enough. Clamp work
securely.
4. Introduce cooling if it is not being used.
5. Faulty material; scale or hard spots.
6. Blade gullets may be loaded. Use higher viscosity
lubricant or coolant.
7. Blade speed and feed may need adjustment.
9
Premature Blade Breakage
1. Poor weld in the blade.
2. Feed rate set too high. Reduce it.
3. Excessive blade speed. Adjust it.
4. Blade guides set too tight or misaligned.
5. Blade tension set too high.
6. Blade running against flange on wheels. Adjust
wheel pitch.
Blade Squeal
1. Feed rate too light for blade speed. Increase feed
rate and/or reduce blade speed.
Blade Slips Off Band Wheels
1. Blade not tensioned correctly.
2. Wheel pitch not set properly.
3. Guides set too tight.
Gullets of Blade Teeth Loading
1. Blade pitch too fine. Review blade selection.
2. Incorrect blade speed. Consult cutting chart.
3. If not using coolant, apply it.
Chips Welding to Blade Teeth
1. Cutting rate too high.
2. Chip brush may be out of adjustment.
3. Check coolant and application.
Blade Becoming Scored
1. Saw guides may be worn. Check and replace if
necessary.
2. Too much pressure on saw guides. Adjust.
3. Guides may be out of alignment.
Blade Making Belly-Shaped Cut
1. Blade tension too light. Increase it.
2. Saw guides too far from work piece.
3. Blade pitch too fine. Use larger pitch and
positive rake tooth form.
4. Excessive feed. Decrease it.
5. Dull blade
Inaccurate Cut-Off
1. Is conveyor or stock stand level with saw bed?
2. Insufficient blade tension.
3. Blade guides too far apart. Always set blade
guides as close to the piece as possible.
4. Blade may be dull. Check and replace if
necessary.
5. Feed pressure too high. Reduce it.
6. Blade guides loose, worn or out of alignment.
7. Too many teeth-per-inch. Blade not cutting
freely.
8. Chip brush not cleaning teeth properly.
9. Dirty coolant.
10. Check for loose fasteners.
Rough Cut / Poor Finish
1. Excessive feed rate. See recommendations.
2. Blade too coarse. Use finer blade pitch.
3. Inadequate cutting fluid. Replace.
Blade Stalls in Work
1. Insufficient blade tension.
2. Excessive feed pressure.
3. Blade tooth spacing too coarse.
4. Motor worn or defective.
5. Guides too tight against blade.
Blade Does Not Track Properly
1. Set wheel pitch so that blade runs to wheel
flange but not against it.
2. Is blade tension correct?
3. Is back of blade riding against backup
bearing? If not, adjust it.
Motor Overheating
1. Check for correct voltage supply. Check
voltage at motor. Check magnetic starter heaters.
2. Check for loose electrical connections.
3. Does motor amp reading correspond to rating
on motor specifications tag?
4. Is internal motor wiring correct?
5. Is drive belt over tightened?
Automatic Stop
When the blade has completed a cut through the
material, the saw frame drops onto a limit switch
actuator which shuts the motor off.
When changing a blade or doing any other
maintenance or repair, be sure the automatic stop
is engaged and disconnect the main power supply.
It is necessary to raise the saw frame to clear the
limit switch actuator before the saw can be started.
10
PLACING THE BLADE ON SAW
To insert a new blade, turn the Adjusting Knob
(item 17 in the parts diagram) on the blade guide
Counter Clockwise (CCW) until it stops. Insert
the new blade and turn the Adjusting Knob
Clockwise (CW) until it stops. The spring loaded
carbide guides will then be in proper contact with
the sides of the blade. The back of the blade
should just touch the carbide back up guide (15 in
the parts drawing). The side bearings should have
a gap of .038 for the .035 thickness blade.
Wheel Pitch Adjustment
If the saw blade runs too low, runs off the wheels,
or runs too high and rubs the wheel flange, a
wheel adjustment must be made.
Loosen the blade before making the following
adjust-ments.
Idler Wheel:
Blade running too low or off the wheel- adjust the
idler wheel block. Loosen the two cap screws in
the block, opposite the take up screw end, one-half
(Y2) turn. Tighten the opposite two cap screws
one-half (Y2) turn. Repeat if necessary.
Blade running too high and against the idler wheel
flange- The blade can become distorted, its top edge
rolled over and wheel flange will wear excessively.
To correct this, loosen the two cap screws closest
to the take up screw one-half (Y2) turn. Tighten
the opposite cap screws one-half (Y2) turn. Repeat
if necessary.
Drive Wheel:
Blade running too low or off the drive wheel-
Loosen the two cap screws opposite the outside
end of the wheel plate one-half (Y2) turn. Tighten
the two set screws on the same end one-half (Y2)
turn. Repeat if necessary.
Blade running too high, and against the drive
wheel flange- Loosen the cap screws closest to the
outside end of the wheel plate and loosen the two
set screws at the same time by the same amount.
Repeat if necessary.
Make certain all screws are tight after adjustments
have been made.
Variable Speed Drive
The Model 1118SA is equipped with variable
speed pulleys providing infinite speed selection
between 70 and 375 feet-per-minute. See Cutting
Speed Chart for settings.
To vary blade speed, rotate handwheel clockwise to
increase speed or counter-clockwise to decrease
speed. Do not adjust the speed unless the pulley
system is in operation (spinning). The handwheel
drag is set at the factory during assembly. This drag
prevents handwheel “creep” during operation but
still permits easy adjustment. Due to normal wear
and environment, the drag setting may change. To
readjust, tighten set screw in thrust nut.
Gear Box Repair
1. Remove gear box from saw.
2. Remove four machine screws holding gear box
together.
3. Separate gear box by carefully prying castings
apart at a location near pulley shaft. Caution: Do
not use excessive force.
4. Once the gear box is open, the internal parts
may be inspected for wear.
5. Liquid plastic gasket is used to seal the gear
case, Loctite No. 51580 or equivalent.
6. Grease, Mobilgrease XHP 220 or equivalent is
recommended. The grease must have excellent
clinging characteristics. (See Lubrication).
Fixed Vise Jaw
The two pins in the fixed vise jaw should be kept in
place in order to ensure square cuts. For cutting
angles, the pins must be removed and the turned to
the desired position and tightened with clamp bolts.
These pins enable operators to quickly relocate the
fixed vise jaw for approximate 90° cutting. For
final, accurate cutting, the fixed vise jaw should be
squared with the blade. (See Guide Alignment)
Sliding Vise Jaw
The sliding vise jaw is fitted with a lift plate and
ratchet dog for quick action. A hand wheel tightens
the vise on the workpiece. Excessive pressure is not
required to hold workpiece securely.
Hydraulic Feed Control
The feed rate is hydraulically controlled with a
needle valve located on the side of the saw bed.
Caution: Do not attempt to loosen or remove hoses
until the saw frame is supported in its “Down”
position.
Feed Pressure Adjustment
Maximum feed pressure is obtained with the frame
spring adjusted as close to the end of the saw frame
as possible. To decrease pressure, turn handle on
opposite end of frame counterclockwise. To increase
pressure turn handle in a clockwise direction. Use
lighter feed pressure when cutting thin-wall material
or irregular shapes.
11
Blade Brush
The brush should be cleaned frequently in
kerosene and reversed to extend effectiveness. For
efficient cutting and blade life, keep blade brush
adjusted so it has contact with the blade teeth at
all times. Replace it as needed.
Motor Overload
The motor starter has a voltage overload to de-
energize the circuit if an overload occurs. To
restart the motor, you need to push the reset
button.
To stop the saw at any time,
press the stop button or
press down on the limit switch actuator
Servicing the Blade Guides
Blade Guide Adjustment
To properly align the saw blade for a straight
and accurate cut, do the following:
1. Square the stationary vise jaw. Make sure it is
square to the front of the vise slot. Check by
placing a combination square against the front of
the vise slot in the saw bed. Slide the square
toward the stationary vise. Make any necessary
adjustment to the vise jaw to bring it into square.
Set the combination square so that one leg is
along the face of the stationary vise and check to
see that the blade is square to the vise jaw. If it is
not square, follow the instructions for horizontal
adjustment.
2. Vertical Adjustment. The back of the saw
blade should just touch the carbide back up guide
(item 15 in the parts drawing) when the saw is
running but not cutting. To adjust, loosen the two
cap screws 8 [A] and move the block up or down
as required. (Before making this adjustment, be
sure the back of the blade is properly contacting
the flange on both the drive and idle wheels).
3. Horizontal Adjustment. Loosen the two cap
screws 8 [B] securing the horizontal adjusting block
(items 11 & 12 of the parts drawing). Turn the top
adjusting bolt (item 13 of the parts drawing) to
move the blade either in, toward the saw bed, or
out, away from the saw bed. Normally, the blade
comes off the Drive Wheel with a minimum amount
of adjustment needed in the Horizontal Adjusting
Block. The Idle End adjusting block is more likely
to require adjustment.
4. Blade Tilt. To ensure the blade is perpendicular
to the bed of the saw, loosen the two cap screw 8
[C] holding the Guide Support (28 & 29 of the
parts drawing) and turn the bottom adjusting bolt
(13 of the parts drawing).
Set the combination square on the saw bed with the
end of the rule butted against the blade above the set
of the teeth. Use a 1-1/2 thousandths (.0015”) shim
and slide it along the top and bottom edge of the
rule where it meets the saw blade. If the shim slides
between the blade and the rule at either the top or
bottom, the blade guides must be adjusted.
5. Safety. Ensure that all bolts are properly
tightened and that all guards are in place before
using the saw.
