Various functions of the saw are carried out via the use of 6 bar compressed air. During these operations, situations would arise where machine parts & materials are clamped together & would potentially pose a serious safety issue to an inexperienced operator. Operators should be thoroughly instructed about these hazards. Only a qualified electrician should carry out regular maintenance of this system.

General Requirements

Lighting

Insufficient lighting during the operation of the saw unit would constitute a safety hazard for the people concerned. For this reason, the user of the machine must provide adequate lighting in the working area to eliminate areas of shadow, whilst also preventing dazzling illumination sources (Reference standard ISO 8995 – 2002 ‘Lighting of Indoor Workplaces’).

Connection

Check that the power supply cables, compressed air supply (if applicable) & coolant system complies with, & are operating within the acceptable range of the saw capabilities.
Faulty, damaged or worn components must be replaced immediately.

Earthing Systems

The installation of the earthing system must comply with the requirements stated in the:
- IEC Standards Part 195: Earthing & Protection Against Electric Shocks 1998.

Advice for the Operator

Ensure that the specimen being cut is secured firmly in the vice clamps & the machine has been correctly set. Figure A show some examples of how to correctly clamp different specimen profiles. Before commencing the cut, be sure the vice(s) is securely clamped & the machine set-up is correct.
Do not use cutting blades of different sizes to those recommended to the machine’s specifications. Always follow safe practices & inspection procedures when installing blades (Please refer to section 5.1 Changing the Blade).
When cutting very small specimens, ensure that the workpiece is not dragged behind the back fence support, where it could get lodged behind the blade.
If the blade jams during a cut, activate the emergency stop function immediately. Do not continue forcing the blade through. This could damage the blade, the specimen or be a cause for potential injury to the operator.
Always turn off the machine before carrying out any repair work. Consult the Brobo Group Engineering Department in the country in which the machine was initially purchased.

Main Functions & Operation of the Machine

Main Features

Saw Safety Guard

The primary purpose of the saw safety guard 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 high-velocity particles that might be dislodged by the cutting process. During the use of the machine do not remove the guard & make sure that they are in correct working order.

Pneumatic Vice Clamp

Pneumatic vice Clamps use air-actuated cylinders to operate the clamping action. They are ideal for quick clamping in repetitive production operations, and yet are portable & economical to use on short run jobs with temporary fixturing. Clamp Switch to activate the clamper to secure the movement of the workpiece.

Up Cut Saw

The saw blade travels up and through the product. When the cut is completed, the saw blade returns to its down position.

Preparation for Operation

The following procedure is recommended for the correct cutting using the Brobo Group TNF400/500/600 Upcut 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

Cleaning
- Using a non-flammable & toxic free solvent, clean the machine to remove any corrosion protective coating prior to use.
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.
E-Stop Button
- Ensure that E-Stop Button is in the out, extended position. E-stops are not used to stop equipment for production problems that do not affect safety.
Clamp Switch
- The product is placed on to rotary table horizontally. Press the clamp switch to secure the product.
Safety Guard
- Close the safety guard
2 Cut Buttons
- Push and hold 2 cut button to start. This is one of the saw safety features to make sure that the saw can only be operated by 2 hands. Release the cut buttons to finish the cut. Press the clamp switch for the clamp to release the product.

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.

WARNING: BLADE MOTOR OVERLOAD

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.

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.
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.
The rate of feed affects the quality of the final cut & blade life. This varies also by the material & crosssectional dimensions.
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 Ferrous Metal Cutting Saw.

Drawings, Layouts, Assembly & Spare Parts

Changing The Blade

All air and electrical connections should be disconnected.
Protective covers must be removed.
The nuts on the motor spindle where the saw is installed are must be removed from the saw place by opening in the opposite direction to each others.
After the saw is replaced with the new one, the same procedure is reversed.
After the saw is replaced the covers are replaced too.

FILTER-REGULATOR

The first condition for a pneumatic system to function properly is to supply enough and quality pressured air.

Pressure regulator
Air pressure manometer
Condensate unit
Nipple for condensate discharging
Regulating screw for oil feeding
Oil unit

Filter cleans the compressed air of impurities, rust, pipe deposits and condensation.

SETTING INSTRUCTIONS

Pressure Adjustment: Regulator head shown with 1 is pulled up. If it is turned on in the clockwise direction lubricators’ outlet air pressure will increase. If turned in counter clockwise direction, the pressure will decrease.
Condensate discharging: The emptying screw shown with number 4 is opened and the condensate liquid will discharge.
Oil filling: Oil unit shown with number 6 is pulled off by turning it on clockwise direction. Then pneumatic oil is added to the container.
Oil speed adjustment: If the adjustment screw shown by number 5 is turned in the clockwise direction, the oil speed will decrease if screw is turned in the opposite direction, it starts giving oil faster to the system. Oil output should be as one drop / minute at air feeding.

COOLING SYSTEM

Coolant Spray speed regulator
Coolant tank
Pneumatic cylinder
Hydraulic speed control cylinder
- Cutting fluids are various fluids that are used in machining to cool and lubricate the cutting tool.

HYDRAULIC SPEED CONTROL CYLINDER

The hydraulic speed control check normally couples with a pneumatic cylinder to provide uniform speed control.

Speed control regulator
Reserve tank
Cylinder
- Speed control is adjustable by (1) regulator.

MAINTENANCE

The speed control check is a closed system and there are no external factors that can adversely affect its function. Care however, has to be exercised not to allow the hydraulic fluid level to drop below the minimum indicated on the auxiliary tank. Should this occur, cavitation, or worse, an air pocket would result causing erratic control. Additional fluid should be put in exclusively through a unidirectional valve by means of an appropriate syringe (such as code number1400.99.01). Excess fluid will be expelled through a vent into an appropriate container. It is necessary to completely disassemble the regulator and be sure to bleed the system to eliminate air pockets. We suggest that you create a vacuum before beginning to refill. This can be done with a small unidirectional valve turned up and repeatedly loaded with a syringe. The rod must be manually actuated successively releasing air through the valve using a small and pointed instrument.

Maintenance & Selection of Consumables

Role of the Operator

The person operating & maintaining the Brobo Group TNF400/500/600 Upcut 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 requirement is complied with.
Ensure that the working cycle is efficient & guarantees maximum productivity, inspect the:
- Functions of the main components of the machine
- The sharpness of the blade & coolant flow
- 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.

Maintenance Requirements

All maintenance must be carried out with the power switched off & the machine in emergency stop condition.
To guarantee for 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.

General Maintenance of Functioning Components

The general maintenance operations that should be carried out regularly are as follows:

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.
Change oil lubricant as required, or whenever the coolant starts to get dirty or emits a stale odour. The oil lubricant compensation tank should be checked regularly.
Recommended Oil Lubricant Brobo Fluid, Part No:-
- 9601480 Brobo Fluid – Aluminium Cutting Oil (2 Litres)
- 9601481 Brobo Fluid – Aluminium Cutting Oil (20 Litres)
Lubricate the 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.
Clean the vice & lubricate any moving joints or sliding surfaces with good quality oil.
Clean the machine regularly & keep any unpainted surfaces lightly oiled to protect from rust & corrosion.
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.
Ensure that the machine performs cuts perpendicular to the work surface. If not, contact Brobo Group engineering department.

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. 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.

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 sulphur, 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 and 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 .
