CHAPTER 3 - Main Functions & Operation of the Machine
AW HEAD BACK FENCE

3.1.1. Cutting Head

Figure 8. Saw Main Components

As the name suggests, the cutting head is the focal area where most of the specimen cutting takes place. Thus, correct saw blade selection such as size, number of teeth & tooth pitch are all critical factors that determine the overall performance & quality of the final cuts. In addition, the use of correct saw blade provides minimum burr to the workpiece while maximizing the safety to the operator during each cutting procedure.

3.1.2. Saw Safety Guard
The primary purpose of the saw safety guard (Figure 9) is to protect the user from the spinning blade. It also functions as a safety device to protect the operator from any broken tooth, swarf or highvelocity particles that might be dislodged by the cutting process.

Figure 9. Saw Safety Guard

Bro b o G ro up brobo.com.au

3.1.3. Saw Actuator
The actuation unit (Figure 10) is a lead screw electric linear drive with special functions purpose-developed for cold cutting:
Auto cut-piece size detection & setting of saw stroke Constant force cutting Active Overload Feed Control

3.1.4. Pneumatic Vice Clamp
Operating at 600kPa, the vice clamps (Figure 11) firmly secure the workpiece in preparation for cutting. The pressure of each vice clamp could be modified using the pressure regulators located on the main electrical unit door. Each vice must be adjusted manually to accommodate various cross-sectional profiles.

Figure 10. Actuator

Figure 11. Pneumatic Vice Clamp
Bro b o G ro up brobo.com.au

3.1.5. PLC ENCLOSURE

Figure 12. PLC Control Box
Cutting Speed Selection The Brobo Group SA350/400 Semi-Automatic Saw comes with fully adjustable RPM & saw feeding speed. RPM is adjusted on the Spindle RPM radio button. Feeding speed is adjusted at the Feed Rate radio button (Figure 12). The actuation unit feeds at constant force hence the cutting speed will vary also according to the thickness of the cut section. The recommended cutting RPM for Mild Steel is 40 to 60 RPM, for galvanized & stainless steels the recommended cutting speed is 20 to 25 RPM.
Dual Start Button The primary purpose of the dual start buttons is to prevent the user from accidentally activating the machine. Assuming that the power is connected to the machine, both buttons must be depressed simultaneously before the cutting cycle will activate.
End Cut Detect Button The SA350/400 Saw completes a cut using an auto-detect system for determining when it has cut through the piece. This ensures that the saw completes the cut in the fastest possible time. This system works reliably on all RHS & round sections, however, for some profile sections, it will fail to detect the end of the cut & finish cutting too early. The operator can turn this on/off using the END CUT DETECT button. When switched off the saw makes the deepest possible cut

It is also possible to limit the cut depth while END CUT DETECT is on by unscrewing the depth adjustment screw while tightening the screw increases the cut depth. (Figure 13)

Emergency Stop Press the Emergency Stop Button during any operation to

immediately stop the saw.

The saw must be recalibrated after the emergency stop.

Figure 13. Adjustment Screw

(Please refer to section 3.2 Preparation for Operation)

When the Emergency Stop Button has been pressed the 'ON' light will turn off.

Wait 5-10 seconds then release the emergency stop button.

To release the emergency stop button from the depressed position simply twist it in the clockwise direction.

WARNING - BLADE JAMMING
If the saw blade jams during a cut, engage the EMERGENCY STOP immediately. Remove the part, check that the blade is not damage and if need be, replace the blade.

Bro b o G ro up brobo.com.au

3.2. Preparation for Operation
The following procedure is recommended for the correct cutting using the Brobo Group SA350/400 Semi-Automatic Saw
WARNING SAFETY GEAR Protective clothing, safety glasses and gloves should always be worn while loading parts, operating the machine, or undertaking any maintenance work on the saw.

PROCEDURE
1. Cleaning Using a non-flammable & toxic free solvent, clean the machine to remove any corrosion protective coating prior to use.
2. Power On Ensure that both the air & electric power systems are turned on, where applicable. The electrical power source must be available before any pneumatic functions will operate.

3. Calibration

Upon power-up, the saw needs to be calibrated.

Immediately upon power-up pushing the STOP/RESET button will calibrate

the saw. (Figure 14)

The saw will not respond to any other buttons until it is calibrated.

The saw calibrates by seeking both forward & back. The saw will first seek

back, then forward, & MUST home forward against its base

Ensure there are no bars placed across the cutting area.

Once the saw touches the base it will go to the home position, briefly run the blade & wait for the

next command.

Figure 14. Stop/Reset Button (Calibration)

WA RNING - BLA DE C HA NG E
Calibration of the saw must be done after every blade change. Not doing so may result in the blade cutting into the base of the saw or actuator jamming. Ensure that the saw is turned off during blade changes.

4. Angle Adjustment To adjust the angle of the cutting surface, if necessary, loosen the 2 bolts (Figure 15.) Fine-tune the angle required, then replace & retighten the 2 bolts.

5. Vice Clamp Setting
Place the cutting specimen you wish to cut into the vice clamps. With a pneumatic vice, manually adjust the clamps so that the jaws are clamped firmly to the workpiece or with a clearance of 3 - 7mm. (Figure 16) (For correct clamping of material, please refer to section 2.3 Advice for the Operator).

Figure 15. Adjustment

Position the vice clamps & component as close to the blade as possible without interfering with the travel of the blade or guard. Vice relocation is required whenever the head angle is altered.

Figure 16. Clamp Clearance 3-7mm
Bro b o G ro up brobo.com.au

6. Vice Clamp Pressure For pneumatic vices, set the vice clamping pressure from the pressure regulators located on the main control unit door. The vice clamps advance with an approximate 10mm pneumatic stroke to apply a clamping pressure of 6 bar (87 psi).
If for any reason this pressure is not available on a continuous basis, the regulator on the air service unit must be set slightly below the available line pressure, & the safety low-pressure indicator valve needs to be reset to correspond with the newly available pressure. The need to change the pressure is necessary to allow for lighter materials with hollow cross sections to be cut without deforming the walls thicknesses.
7. SET Button Once the workpiece & vices are in position press the SET button (Figure 17) Vice jaws automatically close & apply clamping pressure. The vices will clamp the piece & the saw will begin to seek the workpiece. Once the blade touches the workpiece it will rise slightly & then stop moving. At this point, the vice will release the piece. The saw is now ready to cut the workpiece.
Figure 17. Set Button

8. CUT Button

When ready to cut, press the two CUT buttons simultaneously, (Figure 18)

The vices will clamp the workpiece, the blade will being to

rotate & the saw will lower to cut the piece.

Once the cut is complete the vices will release the workpiece & the saw will

return to the position set before the cut, ready to cut the same piece again.

To continue cutting this piece, simply place more tube in vice & press two

CUT buttons simultaneously.

Figure 18. Dual Cut Button

9. STOP/RESET BUTTON
When ready to cut a different sized piece or to stop the saw during any operation, simply press the STOP/RESET button. (Figure 19)
The saw will stop the current task immediately & return to the home position.

Figure 19. Stop/Reset Button
WA RNING - BLA DE MO TO R O VERLO A D
Saw is equipped with overload monitoring system which detects main motor overload in case of blade jam or inadvertent misuse. In case of overload saw reverses feed, re-establishes correct running of motor & continues the cut. If the saw overload system is reversing feed regularly during a cut, it indicates the blade is worn. Replace the blade promptly at this occurrence changes.

3.3. Operation Recommendations
Select the correct saw blade with the correct tooth pitch & form to suit the material to be cut to provide minimum burr & maximum blade lifespan. o SA350 Blade Sizes 320-350 mm o SA400 Blade Sizes 350-400 mm
Use the smallest diameter blade & coarsest pitch that is practical within the required speed & material limitations.
Generally, use a tooth pitch to give 2 - 4 teeth engagement with the material during cutting. Ensure that sufficient coolant is flowing over the cutting teeth. Do not allow the machine's gearbox to run idle in the upright position for more than 3 minutes otherwise,
damage can occur to the drive system. The rate of feed affects the quality of the final cut & blade life. This varies also by the material & cross-
sectional dimensions. When cutting stainless steel or high carbon steel (Brinell hardness above 200), the slowest speed machine should be used together with a cobalt type high-speed steel blade. As a rule of thumb the softer the component, the faster the rate of speed. Thus, it is recommended that slower speeds be used for hard & tough materials & higher speeds for soft, ductile materials. Note that for non-ferrous materials such as brass, copper, aluminium etc. require much faster speeds than provided on this machine. If these are the majority of materials cut, a Brobo NF Series machine should be considered.

CHAPTER 5 - Adjustments to the Saw Unit
5.1. Changing the Blade
To replace a worn saw blade:
DA NG ER ELEC TRO C UTIO N
Make certain that the power to the saw is turned off before proceeding with changing the saw blade.
1) Disengage the linkage arm that is between the guard linkage system & pivot block (at the pivot block by compressing the spring & moving the bolt through the slot).
2) Slide the saw guard up as far as possible (as if it was opening during a cutting cycle) to gain access to the spindle nose.
3) Loosen the spindle screws (LH thread), using the 14mm hexagonal wrench provided, & remove the counter plate. To loosen the spindle screw, insert the wrench (short end) into the socket head cap screw & firmly knock the wrench with the palm of your hands until the screw is loosened. If this method fails to free the screw, place a piece of timber under the blade of the machine, & loosen (or tighten) the screw while holding the saw head of the machine down (blade against the timber).
4) Remove the worn saw blade away from the spindle hub. Using a soft brush, clean the face of the spindle, counter plate & mounting faces of the blade of any dirt or swarf that was trapped by the previous cutting cycles.
5) Place the old saw blade into the new blade packaging & disposed of it safely. Carefully mount the new blade onto the spindle hub, ensuring that the blade is rotating into & towards the back fence, & replace the counter plate utilizing the drive pins as guides as it passes through the pinholes on the blade.
6) Rotate blade back against the drive pins in a counter-clockwise & finger tighten the spindle screw. 7) Firmly retighten the spindle screws, ensuring that the saw blade spins uniformly & aligned parallel with the
safety guard. 8) Lower the outer guards & make certain the pin of the linkage arm is re-engaged with the track on the inner
guard & reconnect the guard linkage. 9) The new blade is ready for use. To check that the blade is performing correctly, carry out a sample cut on
a piece of off-cut. 10) If optional devices are supplied, mount the stock support & rollers on either side of the clamping table.
Normally stock should feed on the left to right, but it can be feed from the right to left if required.
Bro b o G ro up brobo.com.au

5.2. Adjusting the Cutting Angle

The back jaw wear-plates on the Brobo Group SA350/400 Semi-Automatic Saw are typically fitted in the following manner. For angular cutting, the wear plates should be repositioned to provide the maximum support on one side & clearance on the other (Figure 20).

Standard Cut

Angular Cut 450

Figure 20. Angular Cut Positions
i. To adjust the angle of the cutting surface, loosen the socket head screws shown in Figure 10, located on the back jaw face that clamps the table, using the hexagonal wretch provided.
ii. Fine-tune the angle required. The shot-pins have positive locations at 90 & 45 right & left. Adjust the angle on the back fence to suit.
iii. Re-tighten all the previously loosen socket head screws. The saw is now ready for use.
5.3. Cutting & Feeding Speeds
As previously highlights, the rate of feed largely affects the quality of the final cut. As such, the blade life is also dependent on the feed at which it is cutting the sample material - in particular, the type of material & also the crosssectional dimensions. Thus, to extend the life of the blade, maintain a firm & steady pressure whilst allowing the blade teeth to cut at an optimum rate. Do not force the blade through the material! This could cause numerous problems including breaking the blade teeth, jamming the blade with the cutting part or fracturing the blade spindle.
The cutting action also generates a large amount of heat within the cutting sample due to frictional contact. Should this heat affect the material you are cutting in any way, the heat should be dissipated using the coolant system.
5.4. Refilling the Lubricator
To refill the lubricator bowl, twist the bowl anti-clockwise & slide it down to detach it from the lubricator unit (There is no need to disconnect the air supply to the unit). The unit can now be refilled to the line positioned near the top of the bowl, which is approximately 10 millimeters from the top edge of the bowl. Do not fill the bowl above this line, as the lubricator unit will not function properly. Replace the lubricator bowl in a reverse manner by sliding the bowl upwards, ensuring that the feed tube is located inside the bowl, & twist it clockwise to lock it into position.
Bro b o G ro up brobo.com.au

5.5. Adjusting the Brobolube Unit
When assembled, the Brobolube unit is a precise instrument that supplies an accurate quantity of lubricant directly to the saw blade before it contacts the workpiece. There are 2 control variables available for the operator:
Air Flow (Volume) Delivery Regulated with the tap (needle valve), this can be adjusted from initial, completely closed to fully open states. It is highly recommended that the upper end of the flow range be utilized to allow adequate airflow to deposit & evenly distributed the lubricant onto the blade while maintaining a fine lubricant mix. If the needle valve is not open sufficiently, the air to lubricant ratio may vary & may result in a substandard distribution of lubricant to reach the blade teeth.
Lubricator Flow Rate This controls the fluid flow rate & is adjustable via the slotted needle valve situated on top of the lubricator. The consumption of Brobolube is factory set to 4 drops per minute. This has been examined to produce a sufficient mix of air & lubricant, & it is recommended to use this initial setting. On this setting, approximately 55 cubic centimeters (lubricator capacity) should last for 20 hours of continuous cutting. If for some reason the setting needs to be altered, the needle valve should be turned clockwise to reduce or anti-clockwise to increase the fluid flow respectively.
NOTE i. Although the lubricator is capable of delivering a much higher flow rate of lubricant, it is suggested that you
do not increase the flow rate excessively because: No significant increase in blade life or lubricating efficiency will be achieved (confirmed by test results). Excessive application of Brobolube will only result in a waste of fluid. The excessive application will produce swarf that will be wet (oily) & harder to clean up than dry swarf
produced from the correct supply of Brobolube. ii. The amount of Lubricant (when set correctly) delivered by the lubricator is not easily visible to the naked
eye. If in doubt that lubricant is being delivered, first check to see if lubricator itself is delivering droplets at its sight glass. If still unsure whether lubricant is being delivered, disconnect the supply tubing to the tap (needle valve) & hold the tube against some blotting paper for a few seconds while the lubricator is operating.
Bro b o G ro up brobo.com.au

5.5.1. Lubricating Oil Precautions - Health Hazard Information
The Brobolube lubricating fluid has no known adverse health effects. "Brobolube" is non-toxic, odourless, nonflammable below approximately 350ºC, & non-corrosive, although it may affect some types of rubber. There are no traces of sulfur, chlorine, phenol or nitrates found in Brobolube. When comes into contact with skin, the oil may be removed by wiping away the excess, then washing the contaminated area with detergent & water. If the oil is utilized at high temperatures, appropriate protective apparel should be worn as the oil could cause burns to skin or eyes. If splashed by hot oil, immediately run cold water over the burn area & apply first aid burn treatment. If the Brobolube delivery line breaks or becomes disconnected during operation, ensure that the air supply to the system is disconnected before repairing the problem. It is recommended that footwear with anti-slip soles be worn at all times. Any spills will result in potentially hazardous slippery surfaces & should be dealt with promptly to prevent physical injury resulting from falls. Do not use coarsely, combustible material like sawdust to soak up oil due to the potential risk of spontaneous combustion. Spilled oil should be transferred into non-porous containers of suitable strength. Any remaining oil should be cleaned up with sand or other non-combustible, absorbent material. Place the sand & oil mixture into containers & disposed of by an EPA approved landfill or alternatively, by a suitable non-polluting method. In addition, rags soaked in oil should not be burned. Do not pour oil down the drain, which would ultimately contaminate the water supply & pollute the environment.
For firefighting purposes, either use CO2, dry chemical or foam retardant to extinguish the flames.

CHAPTER 6 Maintenance & Selection of Consumables
6.1. Role of the Operator
The person operating & maintaining the Brobo Group SA350/400 Semi-Automatic Saw must familiarise themselves with these instructions for their own safety & that of the others, in addition to safeguarding the production of the machine. Responsibility must be taken by the user on the general maintenance & up keeping of the unit as specified in this chapter, with particular emphasis on:
Check to ensure that other operators of the machine always aware of and comply with the relevant safety instructions & standards as specified in Chapter 2 - Safety & Accident Prevention. Therefore, check that the safety devices are operational & work perfectly and that personal safety requirements are complied with.
Ensure that the working cycle is efficient & guarantees maximum productivity, inspect the: o Functions of the main components of the machine o The sharpness of the blade & coolant flow o Correct working parameters for the type of material being cut
Verify that the quality of the cut meets the requirements & the final product is free from any machining defects.
6.2. Maintenance Requirements
All maintenance must be carried out with the power switched off & the machine in emergency stop condition.
To guarantee optimum operation, all spare parts must be Brobo Group originals.
On completion of maintenance works, ensure that the replaced parts or any tools used have been removed from the machines before starting it up.
Any behavior not in accordance with the instructions for using the machine specified in this manual may create hazards and/or safety risks for the operator.
Therefore, read & follow all the instructions for use & maintenance of the machine, and those on the product itself.
6.3. General Maintenance of Functioning Components
The general maintenance operations that should be carried out regularly are as follows:
1) Keep the vice clamps, overall machine & path of the cutting blade free of any offcuts, accumulated swarf & coolant using compressed air or preferably thread-free cloth.
2) Observe the oil level on the gearbox. The first oil change should be performed after the initial 60 hours of operation & 500 hours of operation thereafter. Use Brobo Gearbox Oil (Part No. 9501090)
Refilling point is situated in the handle bar mounting threaded hole. The required quantity to refill is 800 ml for the S315/S350/400 gearboxes.
Brobo Group brobo.com.au

3) Change coolant as required, or whenever the coolant starts to get dirty or emits a stale odour. The coolant compensation tank should be checked regularly. Coolant level would expect to naturally decrease over time due to natural evaporation. Use premium quality coolants such as CoolTech 500 or SlideTech 68. Coolant is available from BROBO GROUP Pty. Ltd. in 2 litre & 20 litre packs (Part No. 9301570 & 9501080): Concentrate, Ratio 1:20
4) Lubricate the saw head pivot shaft & rotary table regularly (after every 40 hours of operation, or weekly) with an NLGI 2 extreme pressure grease, Shell Alvania No.1 grease or equivalent.
5) Clean the vice & lubricate any moving joints or sliding surfaces with good quality oil. 6) Clean the machine regularly & keep any unpainted surfaces lightly oiled to protect from rust & corrosion. 7) The air supply for the pneumatic air vices should be checked regularly such that it is free of any condensed
water molecules & the filter should be drained frequently. 8) Ensure that the machine performs cuts perpendicular to the work surface.
If not, contact Brobo Group engineering department. 9) Test that the blade is at right angles to the workpiece back fence.
If not, contact Brobo Group engineering department. 10) Check that the 0 notch on the fixed worktable is aligned with the graduation on the turntable. If not, adjust
as described in Section 5.2. 11) Examined that the precision of the 15, 30, 45 left & right stops are correct & accurate. If they are not
adjusted properly, proceed as described in Section 5.2. 12) Regularly empty out the swarf catcher, resting directly above the compensation tank, of any offcuts & swarf
that has collected during the numerous cutting cycles.

CHAPTER 7 - Troubleshoot

7.1. Troubleshooting For Blade & Cutting Problems

PROBLEM IDENTIFIED
Cuts produced are not at 90 and/or are not perpendicular

DIAGNOSIS
Head speed too low or too high

SOLUTIONS
Reduce or increase head speed respectively.

Blade with worn teeth

Replace with a new blade, with reference to Section 5.1 Changing the Blade.

The angularity of blade to workpiece back fence and vice clamps

Adjust the position of the blade so that it is at right angles to the workpiece back fence using the 0 notch as a reference; set the stops at 45 left & right using the method described in Section 5.2 Adjusting the Cutting Angle.

Blade not perpendicular to the work surface

Adjust the blade using the appropriate screws such that it is perpendicular to the work surface.

Frequent and/or excessive teeth breaking

Broken teeth Incorrect lubricant/coolant fluid
Material too hard Blade not worn incorrectly

Check the hardness of the material being cut corresponds to the capabilities of the blade.
Check the water & oil mixture; check that the holes and/or hose are not blocked; direct the nozzles correctly; check that the lubricant/coolant fluid conforms to those specified in Section 6.3 General Maintenance of Function Components.
Check the cutting speed, feed speed, blade type & parameters are correct for the particular application.
With a new blade, it is necessary to start cutting at half feeding speed. After a normalizing period (cutting surface about 300cm2 for hard materials & 1000cm2 for softer materials), both cutting & feed speeds can be brought up to normal values.
