 Safety rules
 Make sure your work area is cleared of uninvited people and obstacles
every time before you start operating the machine.

 Never step or stand on the roller table. Your foot may slip or trip on the
rollers and you will fall.

 Never wear gloves or loose clothing when operating the machine. It may
lead to serious injury if they are caught in the running machine. Wrap or
cover long hair.

 Never touch the running saw blade with gloves or not. It is dangerous if
your hands, clothing or gloves are caught by the running blade.

 Make sure any use of fire is prohibited in the shop and install a fire
extinguisher or other fire control device near the machine when cutting
titanium, magnesium, or any other material that produces flammable chips.
Never leave the machine unattended when cutting flammable materials.

 Use a water-soluble cutting fluid on this machine. Oil-based cutting fluids

may emit smoke or catch fire, depending on how they are used.

 Never cut carbon or any other material that may produce and disperse
explosive dust. It is possible that sparks from motors and other machine
parts will ignite and explode the air-borne dust.
 Safety rules
 Never adjust the wire brush or remove chips while the saw blade is still
running. It is extremely dangerous if hands or clothing are caught by the
running blade.

 Stop the saw blade before you clean the machine. It is dangerous if hands or
clothing are caught by the running blade.

 Never start the saw blade unless the workpiece has been clamped firmly. If
the workpiece is not securely clamped, it will be forced out of the vise
during cutting.

 Take preventive measures when cutting thin or short pieces from the work
to keep them from falling. It is dangerous if the cut pieces fall.

 Use roller tables at the front and rear sides of the machine when cutting
long work. It is dangerous if the work piece falls off the machine.

 Turn off the shop circuit breaker switch before performing maintenance on
the machine. Post a sign indicating the machine is under maintenance.

electric installation from working properly.

Ground the machine with an independent grounding conductor.

Supply voltage: 90 - 110  of nominal supply voltage.

Source frequency: 99 - 101  of nominal frequency.

Refer to the specification chart under Section 2 for total electric power consumption of the
motors and make sure your shop circuit breaker is capable of this consumption amount. Also use a
power supply cable of proper size to suit the power supply voltage.

3-7
1. Turn off the shop circuit breaker.
2. Make sure the machine circuit breaker switch on the
electrical compartment door is turned to OFF.
3. Remove the screw securing the electrical
compartment and then open the door.
4. Pull the power supply cable and grounding conductor
through the power supply inlet into the electrical
compartment. (Shown right)
5. Connect the power supply cable to the circuit breaker
(N.F.B.) to the R, S and T terminals, and connect the
ground cable to the E terminal.
6. Close the compartment door and fasten the screw
back.
7. Turn on the shop circuit breaker and then turn the
machine circuit breaker switch to ON. The Power
Indicator on the control panel will come on.
8. Turn clockwise to unlock the Emergency Stop button
and press the hydraulic ON button to start the
hydraulic motor.
9. Make sure the sawing area is clear of any objects.
Start the blade and check the blade rotation. If the
electrical connections are made correctly, the blade
should run in a counterclockwise direction. If not,
shut the hydraulics off, turn off the machine as well
as the shop circuit breaker. Then swap the power the
power cable conductors connected to R and T
terminals.
10. Repeat step 6 to 9 to ensure the electrical
connections are in the right order.

Leveling

Place spirit level on the vise slide plates and the work
feed table.

Level the machine in both directions i.e. along and across

the machine. Adjust the level of the machine by turning
the leveling bolts.

Make sure all leveling bolts evenly support the

machine weight.

In some cases, leveling the machine with a slight

slope toward the front of the machine is recommended
as it would prevent coolant from running down cutting
material especially tubes or bundles. To do so, make the
rear end of the machine approximately 10 mm higher
than the level of the front end.

3-8
Anchoring

Normally there is no need to anchor the machine. If the machine is likely to vibrate, fix the machine
to the floor with anchor bolts.

Shock absorption steel plates are provided and can be placed under each leveling bolt to prevent
their sinking into the concrete floor.

Installing roller table (optional)

The roller table is used to support long material at

the rear and/or the front of the machine.

If you have ordered the optional roller table for

cutting long material, position it before or behind
the machine.

Level the roller table and the stand with the

Adjust bolts
machine by adjusting the leveling bolts.

Installing Fire Control Device

Install a fire extinguisher or any other fire control device in the shop in case a fire breaks out.

RELOCATING
We recommend you follow these procedures when relocating or shipping your machine to other
place:
1. Descend the saw frame to its lowest position then turn off the power.
2. Fix the saw frame using the shipping bracket that originally came with the machine.
3. If you are shipping the machine, pack the machine carefully with industrial plastic wraps to
protect it from dust.
4. Use a crane or forklift to raise it. If a crane is used to lift the machine, ensure that the lifting
cable is properly attached to the machine.
5. Do not forget to include the equipments originally furnished including the shock absorption
steel plates and the instruction manual.

BANDSAW CUTTING:
A PRACTICAL GUIDE

INTRODUCTION
SAW BLADE SELECTION
VISE LOADING
BladeBreak -In
SOLUTIONS TO SAWING PROBLEMS

7-1
INTRODUCTION

1. TPI: The number of teeth per inch as measured from gullet to gullet.
2. Tooth Rake Angle: The angle of the tooth face measured with respect to a line perpendicular to the cutting
direction of the saw.
3.Tooth Pitch: Tooth pitch refers to the number of teeth per inch (tpi). 1 inch equates to 25.4 mm.

A distinction is made between constant tooth pitches with a uniform tooth distance, 2 tpi for example, and
variable tooth pitches with different tooth distances within one toothing interval.

Variable tooth pitches, for instance 2-3 tpi, can be characterized by two measures: 2 tpi stands for the maximum
tooth distance and 3 tpi stands for the minimum tooth distance in the toothing interval.
Constant Variable

Min. Max

4. Set: The bending of teeth to right or left to allow clearance of the back of the blade through the cut.
5. Width: The nominal dimension of a saw blade as measured from the tip of the tooth to the back of the band.
6. Thickness: The dimension from side to side on the blade.
7. Gullet: The curved area at the base of the tooth. The tooth tip to the bottom of the gullet is the gullet depth.
SAW BLADE SELECTION

1. Band length
The dimensions of the band will depend on the band saw machine that has been installed.
Please refer to Section 2 – General Information
2. Band width
Band width: the wider the band saw blade, the more stability it will have.

3. Cutting edge material

The machinability of the material to be cut determines what cutting material you should choose.

7-2
4. Tooth pitch
The main factor here is the contact length of the blade in the workpiece.
If it is 4P, 25.4 ÷ 4 P = 6.35 mm, that is, one tooth is 6.35 mm.
If it is 3P, 25.4 ÷ 3 P = 8.46 mm If the number is small, it means that the tooth is large.
What is written as 3/4 is that it is a variable pitch of large (3) / small (4).
The saw blade must contact the cutting material at least two pitches. In the case of a thickness of 15 mm,
4P = OK, 3P = NG.

 The surface conditions will also affect the cutting rate. If there are places on the surface on
the material which are hard, a slower blade speed will be required or blade damage may
result.
 It will be slower to cut tubing than to cut solids, because the blade must enter the material
twice, and because coolant will not follow the blade as well.
 Tough or abrasive materials are much harder to cut than their machinability rating would
indicate.
 Tooth spacing is determined by the hardness of the material and its thickness in cross
section.
 Tooth set prevents the blade from binding in the cut. It may be either a "regular set" (also
called a "raker set" ) or a "wavy set".
 The regular or raker set is most common and consists of a pattern of one tooth to the left,
one tooth to the right, and one which is straight, or unset. This type of set is generally used
where the material to be cut is uniform in size and for contour cutting.
 Wavy set has groups of teeth set alternately to right and left, forming a wave-like pattern.
This reduces the stress on each individual tooth, making it suitable for cutting thin material
or a variety of materials where blade changing is impractical. Wavy set is often used where
tooth breakage is a problem. This is shown in Fig. 7.2 as follows:
Right

Straight Left
Regular (raker) Set Wavy Set
Fig. 7.2 The Saw Set
VISE LOADING

The position in which material is placed in the vise can have a significant impact on the cost per cut.
Often, loading smaller bundles can mean greater sawing efficiency.

When it comes to cutting odd-shaped material, such as angles, I-beams, channel,

and tubing, the main point is to arrange the materials in such a way
that the blade cuts through as uniform a width as possible throughout the entire
distance of cut.

7-3
The following diagrams suggest some costeffective ways of loading and fixturing. Be sure, regardless of the
arrangement selected, that the work can be firmly secured to avoid damage to the machine or injury to the
operator.

BladeBreak -In
Completing a proper break-in on a new band saw blade will dramatically increase its life.

1. Select the proper band speed for the material to be cut.

2. Reduce the feed force/rate to achieve a cutting rate 20% to 50% of normal (soft materials require a larger
feed rate reduction than harder materials).

3.Begin the first cut at the reduced rate. Make sure the teeth are forming a chip. Small adjustments to the band
speed may be made in the event of excessive noise/vibration. During the first cut, increase feed rate/force
slightly once the blade fully enters the workpiece.With each following cut, gradually increase feed rate/force until
normal cutting rate is reached.

OIL RECOMMENDATION FOR MAINTENANCE

INTRODUCTION
For the best performance and longer life of the band saw machine, a maintenance schedule is
necessary. Some of the daily maintenance usually takes just a little time but will give remarkable
results for the efficient and proper operation of cutting.

BASIC MAINTENANCE
It is always easy and takes just a little effort to do the basic maintenance. But it always turns out to
be a very essential process to assure the long life and efficient operation of the machine. Most of the
basic maintenance requires the operator to perform it regularly.

8-1
MAINTENANCE SCHEDULE
We suggest you do the maintenance on schedule.

Before beginning a day’s work

1. Please check the hydraulic oil level. If oil level volume is below 1/2, please add oil as
necessary.(Filling up to 2/3 level is better for system operation.)
2. Please check the cutting fluid level, adding fluid as necessary. If the fluid appears contaminated
or deteriorated, drain and replace it.
3. Please check the saw blade to ensure that it is properly positioned on both the drive and idle
wheels.
4. Please make sure that the saw blade is properly clamped by the left and right inserts.
5. Please check the wire brush for proper contact with the saw blade. Replace the wire brush if it is
worn out.

After ending a day’s work

Please remove saw chips and clean the machine with discharging the cutting fluid when work has
been completed.

Do not discharge cutting fluid while the saw blade is operating because it will cause severe
injury on operator’s hand.

Be sure the saw blade is fully stop, it will be performed after working inspection.

RE-ADJUSTING THE ROLLER TABLE

INTRODUCTION
All the machines manufactured by us pass a 48 hours continuously running test before shipping out
and we are responsible for the after sales service problems during the warranty period if the
machines are used normally. However, there still exist the some unpredictable problems which may
disable the machine from operating.

Generally speaking, the system troubles in this machine model can be classified into three types,
namely GENERAL TROUBLES, MOTOR TROUBLES and BLADE TROUBLES. Although you may have other
troubles which can not be recognized in advance, such as malfunctions due to the limited life-span of
mechanical, electric or hydraulic parts of the machine.

We have accumulated enough experiences and technical data to handle all of the regular system
troubles. Meanwhile, our engineering department had been continuously improving the machines to
prevent all possible troubles.

It is hoped that you will give us your maintenance experience and ideas so that both sides can
achieve the best performance.

RE-ADJUSTING THE ROLLER TABLE

If the feeding table suffers the huge stroke and the alignment is effected, follow the below procedure
to adjust.

TOOL, measuring
Measurement, Horizontal balance

Procedure
1. Screw or loosen the adjusting bolt to attain the horizontal balance (leveling) between the roller
table and the machine frame.
2. Ensure that the machine frame is not struck by the loaded material on the feeding table.
3. Check the leveling by the measuring tool.
4. After finished the adjusting, fix the roller table.

If the feeding table and the machine frame are not positioned under the horizontal balance,
the loaded material may be going up gradually and affect the cutting effect.
