FOREWORD

Put Safety First!

This Safety Section contains important information to help you work safely with your machine and describes the dangers inherent to bandsaws. Some of these dangers are obvious, while others are less evident.

It really is important to PUT SAFETY FIRST. Make it a habit to consider the hazards associated with any action BEFORE

you do it. If you feel any uncertainty, stop and nd a safer approach to the action. If you’re still uncertain, ask for advice

from your supervisor.

The SAFETY FIRST approach is particularly necessary when you do something new, or di󰀨erent, and most people

instinctively recognize this, although impatience may still cause them to take unnecessary risks.

Danger also lurks in the routine task that we have done over and over. Here, familiarity, boredom, or tiredness may lull us into unthinking, automatic repetition. Be alert for this, and when you feel it happening, stop and assess your situation. Review the safety hazards associated with what you are doing. That should get your brain working again.

Certainly production is important, but if you think you’re too busy to put safety rst, think how much production you’ll lose if

you get hurt.

You owe it to yourself, your family, and your co-workers to PUT SAFETY FIRST.

Training

Everyone working on or with the machine must be properly trained with regard to the correct use of the machine, the correct use of safety equipment, the foreseeable dangers that may arise during operation of the machine, and the safety precautions to be taken.

In addition, the personnel must be instructed to check all safety devices at regular intervals.

0.3

Page 7

Dene responsibilities

Clearly dene exactly who is responsible for operating, setting-up, servicing and repairing the machine.

Dene the responsibilities of the machine operator and authorize him to refuse any instructions by third parties if they run contrary to the machine’s safety.

Persons being trained on the machine may only work on or with the machine under the constant supervision of an experienced operator. Observe the minimum age limits required by law.

Condition of Machine and Workplace

Ensure that the machine and its safety equipment are kept in good working order.

Ensure that the work area is well lit, and protected from the elements, such as rain, snow, abrasive dust, and extremes of temperature.

Ensure that the machine is installed with su󰀩cient clearance around it for the safe loading and unloading

of work pieces.

RESPONSIBILITIES OF THE OPERATOR AND MAINTENANCE PERSONNEL

Safety equipment

All machines are delivered with safety equipment that must not be removed or bypassed during operation.

The correct functioning of safety equipment on the machine must be checked:

• At the start of every shift.

• After maintenance and repair work

• When starting for the rst time, and after prolonged shutdowns

Emergency Stop Button (E-Stops)

Always be aware of the location of the Emergency Stop Button(s). Do not allow material or objects to block your access to an Emergency Stop.

Damage

If any changes capable of impairing safety are observed in the machine or its operation, such as damage, malfunctions, or irregularities, then appropriate steps must be taken immediately, the machine switched

o󰀨, locked-out, and the fault reported to the responsible person.

Safe operation

The machine may only be operated when in good working order and when all protective equipment is in place and operational.

Keep a safe distance from all moving parts – especially the blade and vises.

Stock should not be loaded onto the saw if the blade is running.

Long and heavy stock should always be properly supported in front of and behind the saw.

Faults

The machine must be switched o󰀨 and locked-out before starting to remedy any faults.

Safety hazard labels

Safety hazard labels and other instructional labels on the machine must be observed. They must be clearly visible and legible at all times. If they become damaged they must be replaced.

0.4

Page 8

Clothing, jewellery, protective equipment

Personnel operating or working on the machine must not wear un-restrained long hair, loose-tting

clothes and dangling jewellery.

When operating or working on the machine, always wear suitable, o󰀩cially tested personal protective

equipment such as safety glasses and safety boots and any other equipment required by workplace regulations.

Gloves

Experience has shown that careless use of gloves around machinery is a major factor in serious hand injuries.

Gloves should not be worn when operating or adjusting the machine, except:

Wear protective gloves when handling bandsaw blades at blade changes.

Gloves may be worn when handling work pieces, only if the machine is in Manual Mode and the bandsaw blade is not running.

If the machine is running in Auto Mode, and only if the cut parts are greater than 24 inches long, it may be possible to safely wear gloves for handling the cut parts, but the wearer of the gloves must never put his hands near the blade for any reason. If the cut

parts are less than 24 inches long, it is required to arrange their automatic ow into a parts bucket or other suitable arrangement to avoid the necessity to pick them o󰀨 the

machine by hand.

Hearing protection

Ear protection must be worn whenever necessary.

The level and duration of noise emission requiring hearing protection depends upon the national regulations in the country in which the machine is being used.

The actual level of noise emission by band sawing machines depends upon work piece size, shape and material, blade type, blade speed and feed rate.

The only practical course of action is to measure the actual noise emission levels for the type of work that is typically done. With reference to national standards, decide upon the necessary hearing protection required.

In the absence of such measurements, it is advisable for anyone exposed to long periods of moderate to loud noise to wear hearing protection. It is important to understand that hearing loss is gradual and easily goes un-noticed until it is serious and irreversible.

Workplace

A clear working area without any obstructions is essential for safe operation of the machine. The

oor must be level and clean, without any build-up of chips, o󰀨-cuts, coolant, or hydraulic oil.

The workplace must be well lit, and protected from the elements, such as rain, snow, abrasive dust, and extremes of temperature

Nothing may ever be placed on, or leaned against the machine, with the obvious exception of the work piece on the table and conveyor of the machine.

Master Disconnect

Lock-out the machine before undertaking any maintenance or repair work on it. ‘Lock-out’ refers switching o󰀨 the master electrical disconnect switch, and locking it out so that it cannot be switched on again

without authorization.

0.5

Page 9

On Hyd-Mech machines the Master Disconnect Switch will be of one of four types:

• Rotary switch mounted in electrical control cabinet door and inter-locked with door.

• Rotary switch mounted on the side of the operator interface console.

• Lever switch mounted in separate box on the machine.

• Supply disconnect switch supplied by user at installation and usually wall-mounted within sight of

the machine, depending upon local regulations.

In almost all jurisdictions, it is required that owners of industrial equipment establish and post lock-out procedures. Know and use the lock-out procedures of your company or organization.

Residual Risks

The machine is still not completely de-energized if an electrical cabinet door type switch is locked-out.

The line side of the disconnect switch itself remains energized.

Variable speed blade drives store dangerous voltage in their capacitors, and this requires time to dissipate. After locking out power, wait 3 minutes before beginning to work on machine electrical circuits.

If compressed air is supplied to the machine to power a mist lubrication system or other devices, it should be disconnected, and any stored air pressure released before working on the machine.

The weight of individual machine components represents stored potential energy that can be released if they fall when disconnected. Secure these components with adequate hoisting gear before disassembly.

SAFETY HAZARD LABELS

The safety hazard labels attached to your machine represent important safety information to help you avoid personal injury or death. All supervisors, operators, and maintenance personnel must locate and understand the safety information associated with each hazard label prior to operating or servicing the machine. The safety hazard labels shown below are located at various positions on the machine to indicate possible safety hazards. The location and re-order part number of all the safety labels associated with this particular model of bandsaw are indicated at the end of this section of the manual. It is important to replace any safety hazard label that becomes damaged or illegible.

HAZARDOUS VOLTAGE INSIDE

Contact with high voltage may cause death or serious injury. Never perform

maintenance on, or near, electrical components until the machine’s electrical

power source has been disconnected. Lock-out power in accordance with

your company’s lock-out procedures before any such maintenance. The “Stop” or “Emergency Stop” push button does not disconnect the machine’s

power supply. Hazardous voltage is still present in the machines electrical circuits.

The machine’s Electrical Disconnect Switch does disconnect voltage from the machine’s circuits; however hazardous voltage is still present inside the main electrical cabinet, on the infeed

(line) side of the main fuses. Therefore keep hands and tools away from the infeed side of the control panel main fuses. If these fuses need to be replaced, use a fuse puller. Allow three minutes after locking-out power before opening any electrical enclosures. Your machine may be equipped with a variable frequency drive that stores high voltage within its capacitors. Three minutes will allow

su󰀩cient time for this voltage to safely discharge.

Never spray coolant directly at electrical components or cabinets.

Page 10

MOVING BANDSAW BLADE WILL CUT

Do NOT operate with guard removed.

Do NOT place hands or ngers near moving bandsaw blade.

For blade changing, always follow the proper Blade Changing Procedure, as given in Section 3 of this manual.

PINCH POINT

Machine parts may move without warning, either because the machine is operating automatically, or because another person initiates the motion. Keep hands clear of all labelled pinch points, whenever the machine is running. Machine vises can exert great force and cause severe injury. Keep hands clear of vises and work piece when vises are opened or closed. Be aware that vise closing or opening may result in potentially dangerous work piece movement. Be aware also that the opening motion of a vise may create potential pinch points.

MOVING PARTS CAN CRUSH AND CUT

Keep hands clear of chip auger. Lock-out power in accordance with your

company’s lock-out procedures before attempting to clear a jam in the

chip auger. Be aware that the chip auger may start unexpectedly, either because the machine is operating automatically, or because another person initiates the motion. If the chip auger is stalled because of a jam, it may start without warning when the jam is cleared, unless the machine power is locked out.

FOUNDATION, LEVELING AND ANCHORING

Machine location should be carefully selected. A at concrete oor area should be chosen. It should have enough free

space surrounding the machine to enable free access for safe operation and maintenance.

The machine should be leveled in both directions, i.e. along and across its infeed conveyor especially when machine is to be inserted into a larger conveyor system. The photo below shows the conveyor from the infeed side.

Four leveling screws are provided, one in each corner of the machine base. Steel plates are to be placed under each

screw to prevent their sinking into the concrete oor.

NOTES: In some cases leveling the saw infeed and auxiliary conveyors with a slight slope towards the blade are recommended. This will prevent coolant from running down the raw stock. (This is especially true when cutting tubing or bun-

dles).

H-40 INSTALLATION PROCEDURE

1) Machine location should be carefully selected. A at concrete oor area should be chosen and have enough free

space surrounding the machine to enable free access for safe operation and maintenance.

2) Cut strapping and remove conveyor drive & chip bucket from saw rollers.

3) Remove coolant tank & position at the left side of the saw (facing from front).

4) Remove leveling pads from inside coolant tank & place under saw base leveling bolts.

5) Check machine level from side to side & back to front. A slight incline (1/8”-1/4” rear of saw higher) will assist

coolant ow back into return tray. Ideally if the machine is sitting at on the oor & the level is good do not

touch leveling bolts. If leveling bolt adjustment is necessary use shims supplied and place under 6 corners of

base frame. Remove leveling bolts and re-check level. If level is unchanged anchor machine to the oor using

adjusting bolt holes.

6) Install infeed conveyor drive with bolts supplied. Install the conveyor drive chain.

1.4

Page 15

For machine shipping purposes the following items have been removed from the saw.

• Infeed conveyor gearbox and motor

• Bearing housing support

• Chain guard

Once the machine has been installed, levelled and anchored the above three items are to be installed as follows:

1. Install the gearbox and motor (1) using the four bolts and use the gearbox as a tensioner by moving it up and down before completely tightening the four bolts.

2. Install the chain guard over the sprockets.

3. Install the bearing housing support (2).

4. Install the chain guard (3).

1.5

Page 16

HYDRAULIC OIL AND CUTTING FLUID

The H-40 bandsaw is supplied with Texaco 46 hydraulic oil. If it in necessary to change the oil to di󰀨erent brand see the

HYDRAULIC SECTION for equivalent grade oil.

No cutting uid is supplied with machine. There are two types of coolant available:

-Oil based; dilute 1:10 ratio. (one part concentrated coolant to 10 parts water)

-Synthetic; dilute as recommended by the manufacturer.

WIRING CONNECTIONS

After the machine is leveled and anchored the necessary power hook-up needs to be performed. In order to provide

a safe operation as well as to prevent potential damage to the machine, only qualied personnel should make the

connections.

BEFORE START-UP THE FOLLOWING TWO POINTS SHOULD BE CHECKED:

-Signs of damage that may have occurred during shipping to the electrical cables and the hydraulic hoses.

-The hydraulic oil level is between the upper and lower lines on the level gauge on the front of the control panel base.

As supplied, the machine is set to run on three phase voltage as indicated on the serial plate and voltage label. Power connection to the machine is made to machine disconnect and ground connections inside the electrical panel as shown below.

During the initial hook-up it is very important to check that the phase order is correct. This is indicated by the hydraulic pressure gauge registering a pressure rise and the blade running in a counter clockwise direction. If the hydraulics do not

ATTENTION:

1) Running the hydraulics “backwards” can damage the hydraulic pump.

2) After checking the hydraulic pressure and BEFORE INSTALLING the drive chain between

the infeed conveyors, check that the conveyors are running in the correct direction. If they are not, change any two phases at the MOTOR JUNCTION BOX for each motor as required.

Power connections should be made by qualied personnel only

SECTION 2 - OPERATING INSTRUCTIONS

This section has been prepared to give the operator the ability to set up the saw for most cutting situations. Before cutting any material, the operator should be familiar with all operations and controls as well as the basic cutting theory described below. The saw is equipped with variable blade speed and hydraulic feed control, as well as an extensive door chart to guide the operator to the correct setting of these controls.

BLADE BASICS

Technology is rapidly changing all aspects of production machining. Metal cuto󰀨 is no exception. The advances made in the bandsaw blade industry have denitely brought down the cost per cut, despite the three fold higher price of high

technology blades. Variable pitch, bi-metal blades (like the 4/6 or 3/4 bi-metal blade supplied with the machine) last much longer, cut faster, and more accurately than conventional carbon steel blades. In order to take advantage of the superiority of bi-metal blades, it is critical to properly “break-in” a new blade. This is accomplished by taking two or three cuts through

solid four or ve inch diameter mild steel at an extremely slow feed rate. (It is also advisable to utilize a slow blade speed)

These two or three slow cuts su󰀩ciently lap (polish) the teeth on the new blade so that it does not snag the material being cut. Proper break-in will alleviate blade vibration; improve surface nish, accuracy, and blade life.

After “break-in”, the following six points must be closely monitored to ensure long blade life:

1. Proper blade tension should be maintained. (See Section 3, Maintenance and Troubleshooting)

2. Generous coolant application is essential with most materials. A high quality and well mixed coolant will extend blade life, and also increase cutting rate and quality. On those materials where coolant is undesirable for cutting,

a slight coolant ow or periodic oiling of the blade is necessary to prevent the blade from being scored by the

carbide guides.

3. The stock being cut must be securely clamped in the vises.

4. The proper feed force should be chosen. (see Saw Cutting Parameters: Step 2)

5. The proper blade speed must be selected. (see Saw Cutting parameters: Step 4)

6. The proper feed rate must be applied. (see Saw Cutting Parameters: Step 5)

VARIABLE SPEED CONTROL

Blade speed can be adjusted innitely between 75 and 270 SFM (Surface Feet/Minute) (23 to 82 m/min) Adjustment should be made only when the blade is running. Clockwise rotation of the knob increases blade speed while counter clockwise rotation decreases blade speed.

THE CONTROL PANEL

START-UP

The control console has been designed to simplify the operation of the saw, to give the operator the ability to stop any function at any time, and to be able to control all the functions remotely. We cannot overstress the importance of familiarizing yourself with the controls prior to star ting the machine.

NOTE:

1. ALL SWITCHES MUST BE IN THE CENTER NEUTRAL POSITION TO START THE MACHINE!

2. WHEN STARTING THE MACHINE FOR THE FIRST TIME MAKE SURE THAT BLADE IS MOVING IN A

COUNTERCLOCKWISE DIRECTION, AND THAT THE HYDRAULIC PRESSURE IS:

-1200 PSI FOR H-40/40 AND H-40/60

-1300 PSI FOR H-40/80

MANUAL OPERATION

Manual Operations can be performed by using the control buttons on the HMI. All functions are self-explanatory. Specic

control button functions are described on the following pages.

2.1

Page 19

EMERGENCY STOP

Stops blade and hydraulic motors. Head motion will stop and vise clamping pressure will begin to fall o󰀨. Long pieces of work should always be supported so they will not become loose over time and fall while the machine is shut down. This is a latched button and must be pulled out to start the machine.

BLADE STOP

When depressed the blade will stop. Blade motor will stop automatically when head reaches head down limit switch.

HEAD CONTROL

This switch has three positions: UP, HOLD, and DOWN. UP causes head to rise until it mechanically cannot raise any higher or the switch is moved to HOLD. In HOLD head movement stops. In the DOWN position the head will descend until it reaches the lower limit switch. The speed or rate of descent is controlled by the FEED RATE VALVE.

CONVEYOR FORWARD

When depressed, the selected conveyor’s rollers rotate in a direction which would move material

forward from behind the saw head toward the front of the machine. Releasing the push button deactivates conveyor motor(s) and movement will stop.

FRONT VISE

This switch has three positions, OPEN, NEUTRAL and CLOSE. With the switch held in the OPEN position the vise will open all the way or until the switch is released. With the switch in the NEUTRAL position, the vise will stay where it is and will not move freely although it will not resist

a large force indenitely without creeping. In CLOSE, the vise will close all the way, or until it

encounters enough resistance to stop it.

HYDRAULIC START

To start the hydraulic system, the switches for the head and vises must be in the “NEUTRAL” position. The “HYDRAULIC START” button must be depressed and held in momentarily until the PLC display becomes active.

BLADE START

Starts the blade when depressed. Only active with hydraulics running and saw head up, o󰀨 of

lower limit switch.

GUIDE ARM

Three position, spring centered switch. When held to the IN position, the moveable guide arm will

move in toward the xed guide arm. OUT retracts the moveable arm away from the xed guide

arm. When released, the switch returns to the center position allowing no guide arm movement.

ENSURE CLEARANCE BETWEEN GUIDE ARM AND VISES AT ALL TIMES.

CONVEYOR REVERSE

When depressed, the selected conveyor’s rollers rotate in a direction which would move material toward the back of the machine. Releasing the push button deactivates conveyor’s motors and

movement will stop.

REAR VISE

a large force indenitely without creeping. In CLOSE, the vise will close all the way, or until it

encounters enough resistance to stop it.

BLADE SPEED

Allows for increase or decrease of blade speed while blade motor is running.

COOLANT

This switch has three positions, AUTO, OFF, and ON. In the ON position, the coolant system

will operate when there is power to the machine; this allows using the wash gun to clean the

machine. In the OFF position, the coolant system is inactive. In the AUTO position the coolant system will only run when the blade is on. The coolant system can also be run only when both

the blade is on and the head is descending by selecting this option in the PLC parameters.

CONVEYOR SPEED

Allows for increase or decrease in speed of selected conveyor(s) when FORWARD or REVERSE push buttons are depressed.

2.3

SAFETY LOCK

This lock is provided for the safety of the operator during the blade changing procedure. When the lock is in the “ON” position, the door interlocks are disabled and the only functions that are active are the HEAD and BLADE TENSION controls. All other controls are inactive. After the blade has been changed the lock must be switched to “OFF” in order to operate the machine.

LASER

This option switch has two positions, OFF & ON.

CONVEYOR SELECT

Three maintained positions: INFEED, BOTH, and OUTFEED. Selects the conveyor(s) to move when the CONVEYOR FORWARD or REVERSE PUSH BUTTONS are used.

BLADE TENSION

Located in the idler wheel box, is a three position maintained switch: Normal running position is +/RUN. This position will keep constant tension on the blade. In the center HOLD position the idler wheel is held in position with not tension applied to the blade. The “-“ position retracts the idler wheel, releasing blade tension and allowing for blade removal.

DISPLAY

The following information is displayed on the E1012 HMI:

1. Head Height. (Inches)

2. Feed Rate. (Inches/minute)

3. Blade Speed. (surface feet/minute)

CUTTING PARAMETERS CHART

A full size CUTTING PARAMETERS CHART is mounted on the front of the saw. The chart contains ve steps for the

operator to follow in order to achieve optimum performance of the saw. These steps are detailed on the following pages.

Saw Cutting Parameters Chart

CHART EXAMPLE #1

We will use the parameters chart to set up the saw for cutting 8” (200mm) Diameter #1045 Carbon Steel.

STEP 1: DETERMINE EFFECTIVE MATERIAL WIDTH - W (inches) or (mm)

E󰀨ective material width, W (in.) for most common shapes of materials, is the widest solid part of the material to be in

contact with blade during cutting. For simple shapes, as illustrated on the chart, this can be directly measured. For

bundles of tubes and structurals, measuring the e󰀨ective width is di󰀩cult. E󰀨ective width is 60% to 75% of the actual

material width.

Material Width Chart

NOTES:

1. E󰀨ective material width, as determined here in STEP 1, can be thought of as the average width of material “seen”

by each tooth, and it is used in STEPS 3 and 4.

In Example #1, for an 8” (200 mm) diameter solid, E󰀨ective Material Width is 8” (200mm).

2.7

Page 25

STEP 2: SET FEED FORCE LIMIT (DOES NOT APPLY TO H40 MACHINES AS FEED FORCE IS FACTORY PRESET)

The Feed Force Limit is the maximum amount of force with which the head is allowed to push the blade into the work-piece.

CUTTING SOLIDS

For cutting solids, the wider the section, the less FF should be set, to avoid blade overloading. See the graph below.

% OF FF

SETTING (INDICATED ON LABEL)

MAT’L WIDTH AS %

OF SAW CAPACITY

EXAMPLE: When cutting a solid which is 1/2 of machine capacity using the graph, locate 50% on the horizontal line and

travel upwards to the plotted line and then travel directly across to the vertical FF Setting line. The point that you have

arrived at shows a setting of 40% for a piece 50% of capacity.

CUTTING STRUCTURALS: A reduced Feed Force Setting is used when cutting structurals.

2.8

Page 26

STEP 3: DETERMINE OPTIMUM BLADE PITCH - TEETH PER INCH (T.P.I.)

Selecting a blade with proper tooth pitch is important in order to achieve optimal cutting rates and good blade life.

For cutting narrow or thin wall structural materials a ne blade with many teeth per inch (T.P.I.) is recommended. For wide

materials a blade with a coarse pitch should be used. The sketch can be referenced for the blade pitch changes for

di󰀨ering e󰀨ective material widths.

Optimum Blade Pitch (T.P.I) for Material Width (Inches)

It is impractical to change the blade to the proper pitch every time a di󰀨erent width of material is cut and it is not necessary, but remember that the optimum blade will cut most e󰀩ciently. Too ne a blade must be fed slower on wide

material because the small gullets between the teeth will get packed with chips before they get across and out of the cut. Too coarse a blade must be fed slower because it has fewer teeth cutting and there is a limit to the depth of a cut taken by each tooth. Allowance for the use of a non-optimum blade is made in STEP 5.

Example #1: E󰀨ective material width of 8” (200 mm):

Optimum blade has 2/3 teeth per inch.

2.9

Page 27

STEP 4: DETERMINE OPTIMUM BLADE SPEED, V (ft/min) (m/min)

The relationship between optimum blade speed and e󰀨ective material width for various materials is represented on the

graph shown.

The graph shows that as e󰀨ective material width gets wider or as material gets harder, lower blade speeds are recommended. If material is narrow or soft, higher blades speeds should be selected.

Example #1

1. 8” (200mm) diameter #1045 Medium Carbon Steel solid bar is to be cut.

2. On the graph above nd the Medium Carbon Steel Curve which represents the optimum blade speeds for 1045

Carbon Steel.

3. On the horizontal axis (e󰀨ective material width axis) nd number 8 which represents e󰀨ective material width of an

8” (200mm) diameter solid.

4. Find the point where a vertical line from 8” (200mm) intersects the Medium Carbon Steel Curve.

5. From this intersection point run horizontally left to the vertical axis (optimum blade speed axis) and nd the point

marked “200”.

6. For 8” (200mm) diameter, 1045 Carbon Steel solid bar 200 ft/min (60m/min) is the optimum blade speed.

NOTE:

1. Higher than optimum blade speed will cause rapid blade dulling. Lower than optimum blade speeds reduce

cutting rates proportionately and do not result in signicantly longer blade life except where there is a vibration

problem. If the blade vibrates appreciably at optimum speed as most often occurs with structurals and bundles, a lower blade speed may reduce vibration and prevent premature blade failure.

2. Material Hardness - The graph above illustrates blade speed curves for materials of hardness 20 RC (225 Bhn) or lower. If the material is hardened then the multipliers need to be used. These multipliers are given in the NOTE at the bottom right of the graph. As the hardness increases the optimum blade speed decreases.

2.10

Page 28

The following table gives examples of the optimum blade speeds for di󰀨erent materials.

# MATERIALS OPTIMUM BLADE SPEED

1 5” (125mm) Diameter Solid Carbon Steel 225 70

2 12” (300mm) I-Beam 290 90

3 4” x 4” (100mm x 100mm) Rect. Tube 1/4” (6mm) Wall 350 110

6 3” x 3” (75mm x 75mm) Inconel 60 20

Materials and Blade Speed

STEP 5: DETERMINE FEED RATE SETTING, FR (in/min) (mm/min).

FEED RATE is the vertical speed at which the blade descends through the work-piece.

The FEED RATE Knob controls FEED RATE of the blade descent. The FEED RATE should be adjusted only in one direction (from “O” to required value). If you go too far, go back to “O” and come back up. To set FEED RATE for particular cutting situations use the graph below, which represents the relationship between FEED RATE, blade speed and blade pitch.

Example #1: It is known from Step 3 that optimum blade pitch is 2/3, and from Step 4 that blade speed is 200 ft/min (60mm/min). From the Graph on the left, the FEED RATE is determined in the following way:

1. On the horizontal axis (blade speed axis), nd

200 ft/min (60mm/min).

2. Find the point where a ver tical line from 200 ft/min (60mm/min) would intersect the 2/3 blade pitch curve

3. From this intersection point run horizontally left to the ver tical (FEED RATE) axis, to ar rive at 1.8 in/min (45mm/min) FEED RATE. Thus 1.8 in/min (45mm/min) is the FEED RATE for cutting 8” (200mm) diameter 1045 Carbon Steel when the optimum 2/3 pitch blade is used.

Feed Rate Calculation

2.11

Page 29

FEED RATE, continued

If the saw is tted with a blade coarser than optimum (e.g.: 1.4/2.5 TPI) we can still use the graph, but we go to the 1.4/2.5 curve. As a result we nd that the FEED RATE is decreased to 1.3 in/min (133mm/min) for this blade. If however, the machine is tted with a ner than optimum blade (e.g. 3/4 TPI) we use the graph for the optimum blade as before, and

then use a multiplier given by the table below.

Optimum Vs Actual Blade Pitch

ADDITIONAL CUTTING SETUP EXAMPLES

EXAMPLE # 2

Material: Round Steel Tube SAE 4320 - Hardened to 35 RC (325 Bhn ) Dimensions - 6” O.D. x 4” I.D. (150mm O.D. x 100mm I.D.)

Step 1 E󰀨ective Material Width: 4 1/2” (.75 X 6) 114mm (19 x 6)

Step 2 Feed Force limit setting for 6” Diameter material (Refer to Feed Force Limit, Setting in Step 2)

Step 3 Optimum blade pitch (TPI): 3/4 T. P. I.

Actual blade pitch on the saw: 4/6 T. P. I.

Step 4 Optimum blade speed for 4 1/2” e󰀨ective 225 ft/min (70m/min) material width

Blade speed reduced by hardness factor: 225 ft/min X .60 = 135ft/min (70m/min x .60 = 42m/min)

Step 5 Feed Rate for 3/4 TPI blade: 1.8 in/min (45mm/min)

Feed Rate for 4/6 TPI blade: 1.8 in/min X .70 = 1.3in/min

(reduced by ner than optimum blade pitch factor) (45mm/min x .70= 31.5mm/min)

GUIDE ARM POSITIONING

The adjustable guide arm should always be adjusted with respect to the material width. It will optimize cutting conditions and increase blade life with the guide arm adjusted as close to the material as permitted.

In order to adjust the guide arm, the remote guide arm adjustment switch, located on the control console is used to hydraulically position the guide arm. Turn the switch clockwise to move the guide arm toward the stock. Turn the switch counter clockwise to move the guide arm away from the stock.

ENSURE CLEARANCE BETWEEN GUIDE ARM AND VISES AT ALL TIMES.

COOLANT CONTROLS

GUIDE ARM

A generous ow of coolant should be applied in order to increase production and blade life. The machine is provided with

adjustable coolant on the left side of the operator panel as shown below.

A properly adjusted ow of coolant should cover the blade (from the adjustable guide arm) which in turn will carry it into

the cutting area. Additional coolant can be supplied with the coolant bars shown below which are controlled by the knob labeled ‘FLEX HOSE”.

NOTE: When cutting materials that do not need coolant (cast iron), some coolant ow is required to provide blade

lubrication and prevent scoring of the blade by the carbides.

SECTION 3 – MAINTENANCE

SAFETY DURING MAINTENANCE AND TROUBLESHOOTING

“Lock-out”, or “Lock-out Tag-out” are terms that refer to procedures taken to prevent the unexpected start-up, or other release of energy, by a machine, whenever anyone is required to remove or bypass safety guards or devices, or whenever anyone is required to place part of his body in a hazard area. In almost all jurisdictions, it is required that owners of industrial equipment establish and post lock-out procedures. Know and use the lock-out procedures of your company or organization. In the absence, of such posted procedures, use the following procedure.

LOCK OUT PROCEDURE

Whenever work is to be performed on a machine, which requires removal or bypassing of safety guards or devices, or the

placement of part of anyone’s body in a hazard area, the following steps shall be taken:

1. Operator shuts down the machine.

2. The supervisor in charge of the machine must be informed of the intention to Lock-out the machine.

3. The FEEDER power which supplies power to the machine and which is connected to the machine via the Power Junction Box (see picture below) must be turned OFF and locked in the OFF (0) position by means of a padlock. The key for this padlock must be kept by the person performing the work on the machine. If more than one person is performing work on the machine, then a multiple lock hasp shall be used, and each person shall apply his or her own lock to the hasp.

4. The Machine Power Disconnect Switch must be turned OFF, and locked in the OFF (0) position by means of a padlock. The key for this padlock must be kept by the person performing the work on the machine. If more than one person is performing work on the machine, then a multiple lock hasp shall be used, and each person shall apply his or her own lock to the hasp.

5. Prior to starting any work on the locked-out machine, the supervisor shall attempt to start the machine to ensure that the lock-out device provides adequate protection. Operating controls must be reset to the “OFF” position after this test.

6. Work on the locked-out machine may now proceed.

MACHINE DISCONNECT SWITCH USED FOR SAFETY LOCKOUT PURPOSES

Machine Power Disconnect located on the door of the high voltage electrical panel, mounted on the drive side machine post.

1. Ensure switch is in the OFF position.

2. Install padlock and lock it.

3.1

Page 34

RESTORING MACHINE TO USE

After completion of all repairs or maintenance to the locked-out machine, it shall be restored to use as follows:

The person(s) who performed the work shall verify that all areas around the machine are safe, before the machine is re-energized. No-one shall be permitted in un-safe areas around the machine. All guards and covers shall be properly installed. Each lock-out padlock shall be removed by the person who applied it. After the lock-out padlocks are removed, and before the machine is started, the supervisor and all other employees who

use the machine, shall be informed that the lock-out has been removed. After notication is made, the machine may be

re-started.

BLADE CHANGE MODE PROCEDURE

Wear safety glasses, gloves, and a long sleeve shirt for protection when handling band saw blades during blade change. NOTE THAT GLOVES SHOULD NEVER BE WORN NEAR A RUNNING BANDSAW BLADE. When handling new blades,

or ones that will be re-used, it is important to keep the teeth out of contact with concrete oors.

This machine is equipped with hydraulic blade tension and a ‘Blade Change Mode’ key switch, located on the operator

control panel.

This key has two positions:

OFF – All normal operations of the band saw are operative.

ON – Hydraulic motor can be started. Blade tension is operative.

3.2

Page 35

BLADE REMOVAL

1. With the blade change mode key switch in ‘OFF’, the blade stopped and the hydraulics ON, raise the saw head

until the drive door will clear the electrical control panel.

2. Move the guide arm out to provide room between the two guide arms to easily grasp the blade with

two hands, BUT DO NOT TOUCH THE BLADE UNTIL THE BLADE CHANGE MODE SWITCH IS TURNED TO

THE ‘ON’ POSITION.

3. Turn the blade change key switch to the ‘ON’ position. The hydraulics will continue to run, but only the blade

tension switch is functional. The blade wheel doors can be opened without the hydraulics shutting down.

4. Open both blade wheel doors.

5. Release the blade tension by turning the switch briey to ‘ – ‘. By jogging the switch between ‘HOLD’ and ‘ – ‘, it is possible to regulate the degree of tension on the blade.

6. Pull the top strand of the blade up, out of its slot above the cutting area and forward out of the slots on the inside walls of the blade wheel housings.

7. Pull the lower strand of the blade down out of the blade guides.

8. Store and dispose of the used blade.

BLADE INSTALLATION

NOTES ABOUT NEW BLADES

• A new blade will come folded into a compact coil. Follow the blade manufacturer’s instructions for safely

unfolding the blade.

• The blade must be installed with the teeth facing towards the rear of the saw where it passes around the wheels, and with the teeth in the cutting area pointing away the drive wheel. This may require that the blade be turned inside out before installation.

1. With the blade change mode key switch remaining in the ‘ON’ position, turn the blade tension switch to the ‘ – ‘

position for several seconds until the idler wheel has fully retracted.

2. Insert the lower strand of the new blade into the blade guides.

3. Lift the upper strand of the blade up into its slot above the cutting area, and place it around the blade wheels.

4. Turn the blade tension switch briey to ‘ +/RUN’ and then leave it in ‘HOLD’ to retain the blade lightly on the

wheels.

5. Adjust the blade position on the wheels so that the blade is not crooked on them and the teeth overhang the back edge of the wheels.

6. Turn the blade tension switch to ‘ +/RUN’.

7. Close both blade wheel doors.

8. Turn the blade change mode key switch to the ‘OFF’ position. The hydraulics will shut down.

9. Switch the hydraulics on, then start the blade and run for 20 seconds.

10. Stop the blade.

11. Turn the blade change key switch to the ‘ON’ position.

12. Open the blade wheel doors and inspect the blade tracking, plus the position of the blade brush. Refer to the manual for tracking adjustments.

13. Close the blade wheel doors and turn the blade change mode key to the ‘OFF’ position.

14. Blade change procedure is now complete.

3.3

Page 36

BLADE BRUSH ADJUSTMENT

The blade brush is properly set when the machine leaves the factory, however, it wears out during operation and needs to be adjusted periodically. The blade brush assembly is shown in the photo. In order to adjust it, the nut on the adjusting bolt needs to be loosened and the brush mounting bracket turned until the wires from the brush touch the bottom of the blade gullets as shown and then tighten the adjusting nut.

If the brush gets worn to approximately 70% of its original diameter, it should be replaced. A brush may be purchased

through a Hyd-Mech Group Limited dealer in your area.

HYDRAULIC MAINTENANCE

There are only FIVE items of routine maintenance associated with the hydraulic system:

1. OIL FILTER – Ten-micron ltration of the hydraulic oil is provided by a spin-on type lter mounted on the tank return line. The element should be changed after the rst 50 Hours of operation and then every 500 working hours. Suitable

replacement elements are:

CANFLO RSE-30-10 GRESEN K-22001 PARKER 921999 ZINGA AE-10

2. OIL LEVEL - The oil level should be maintained in the upper half of the level gauge. Normally the rate of oil

consumption will be very low and it should be unnecessary to add oil more often than at lter changes. Add oil only to the

top line on the gauge. Hydraulic tank capacity is approximately 17 US gallons. The machine is shipped from the factory with Texaco Rando HD 46 hydraulic oil. Generally any brand of recognized mineral hydraulic oil with the same properties should be compatible with Texaco Rando HD 46 oil, but to avoid any risk we

suggest staying with Texaco Rando HD 46. If it is desirable to change brands, it is necessary to drain the tank and to ll to 1/3 with the new oil. Operate through several full strokes of each cylinder, drain the tank again, and nally ll the tank with

the new brand.

Recommended replacement oils: Chevron AW Hydraulic Oil 46 ESSO NUTO H46 Mobil Mobil DTE 25 Shell Tellus 46 Petro Canada Harmony AW 46

3. OIL TEMPERATURE – Oil temperature is indicated by a thermometer contained in the level gauge. Oil temperature during steady operation should stabilize at about 50-55°F (10-12° C) above room temperature. Thus in a 70° F (20° C) shop one might expect an oil temperature of about 120° F (50°C) Oil temperature should never exceed 160°F (70°C).

4. OIL PRESSURE – Oil pressure is factory set to 1500 PSI (10339 kPa) for H-40 and should not require further attention except precautionary observation at start-up and every few days thereafter.

CLEANLINESS

The H-40 series design should endure heavy operating conditions and provide the customer with awless machine

performance. To extend good performance some care is required, especially cleanliness. The following areas should be kept clean of dirt, grease and chips:

CONTROL CONSOLE DOOR CHARTS WHEEL BOXES BLADE GUIDES

NOTE: All parts should be cleaned before any repair or service is performed on them.

BLADE DEVIATION MONITORING SYSTEM (K10)

BLADE DEVIATION MONITORING SYSTEM (K10)

General description of the blade deviation monitoring system.

This system monitors lateral blade deviation during cutting. If blade deflection increases beyond the pre-set warning limit, then the monitoring device sends a warning signal by means of flashing beacon mounted on the top of machine head. If no steps are taken to correct this condition, the machine will continue to cut until the pre-set shut-down limit is reached. At this point the machine will behave in one of two ways, selectable by parameter setting:

1. Stop cutting, raise the head and shut down

2. Finish the cut with present degree of deviation and then shut down.

Operation of the system

The proximity transducers are enclosed in a housing mounted on the idler and drive side guide arms. The sensors convert the blade lateral deflection to an analog signal, which is sent to the PLC and after a series of calculations is displayed on the operator interface in a form of bar graphs. One bar graph for the transducer mounted on the idler guide arm and the second bar graph for the transducer mounted on the drive side guide arm.

The bar graphs appears in both Manual Mode and Automatic Mode Screens. It is only active when the blade is running and head is descending. The length of the bar graph is proportional to the blade deflection. The bar graphs extend from the screen centre towards the right if blade is deviating toward the front of the saw (cutting into the part), and extends from the screen centre towards the left if blade is deviating toward the rear of the saw (cutting into the stock).

If a warning limit is reached and maintained longer than the preset response time, then the beacon light mounted on the top of the head will start flashing.

If a shutdown limit is reached and maintained longer than the preset response time, then the machine will behave in one of two ways: stop cutting, raise the head and shut down or finish the cut with present degree of deviation and then shut down.

The MONITOR LIMIT SETTING screen will be displayed Figure 2.

There are two scales, the upper one showing the preset right and left shutdown limits, and the lower scale showing the preset right and left warning limits. All four limits (right and left warning and right and left shutdown) are set independently.

To adjust limits move cursor to number on right hand side of the screen and key in new value from – 100 to 0 for cut out limit and from 0 to 100 for cut in limit.

Cut out maximum limit – (out - cutting towards outfeed, range 0 ~100). This parameter will adjust shutdown limit if blade is cutting towards the part. Increasing this value decreases sensitivity, which will result in a larger deviation from nominal straight, before shutdown sequence is initialized.

Cut in maximum limit – (in - cutting towards infeed, range -100 ~ 0) This parameter will adjust shutdown limit if blade is cutting towards the stock. Decreasing this value decreases sensitivity, which will result in a larger deviation from nominal straight, before shutdown sequence is initialized.

Cut out warning limit – (out - cutting towards outfeed, range 0 ~100) This parameter will adjust warning limit if blade is cutting towards the part. Increasing this value decreases sensitivity, which will result in a warning further from nominal straight.

Cut in warning limit – (in - cutting towards infeed, range -100 ~ 0) This parameter will adjust warning limit if blade is cutting towards the stock. Decreasing this value decreases sensitivity, which will result in a warning further from nominal straight.

The prompt ‘SET’ appears when the adjustment is within the acceptable range of – 100 +100. [See sensor adjustment procedure section]

This parameter will activate or deactivate response of the blade deviation monitoring system.

(range 0.1 sec – 10 sec) The refresh time is time between bar graph updates. If it is set to low value

then the display will flicker do to vibration of the blade, weld passing by the sensor or other irregularities in the blade.

Figure 4 Parameter description chart.

Relationship between Blade Deflection Display and Actual Cut Deviation

The digital display indicates the blade lateral deflection at the point where it passes the blade deflection sensor, which is 1” past the idler side guide arm. The display range of0 +/-100 is proportional to the amount of blade deviation. This depends on the type of material, shape of the work-piece and amount of blade tension. The maximum deviation of the cut surface will occur at or near the center of the cut, and will be several times larger than that measured at the sensor.

The actual amount is difficult to predict, experience with different work-pieces will provide the best guide.
