GENERAL WARNINGS
This machine was design and built using the state of the art techniques, and with respect of the machine tools European
Laws.
Notwithstanding what above, it is implicit that working underestimating or forgiving the dangers which this kind of machine can generate, the operator could cause a serious injury to him/herself.
Therefore, the operator should carefully read the entire instruction manual, and respect strictly what in it prescribed.
In particular, please pay attention to the following suggestions :
1. Keep always your working area clean.
2. Avoid to keep in your working area pieces of material, chips, cans, or other things which could reduce the possibility of movement for the operator or even generate risks of injury.
3. Be always cautious using the machine, because, even if it is protected in every dangerous spot, it can be a dangerous equipment, and thus it has to be use being particularly careful and aware.
4. Give immediately notice to your supervisor if the machine needs to be maintained or serviced, even if the problem is caused by inexperience. An incorrect use of the machine can be dangerous and can cause injuries.
5. Do not try to repair the problem if you are not sure of what caused it.
6. Never service or maintain the machine when it is running. Always turn it off.
7. Never leave the machine working without respecting the safety rules or removing the safety devices.
8. Remove electrical power when the machine is not working.
9. Always wear protective cloths, especially when replacing the blade.
10. Never do anything imprudent.
11. Never touch the unprotected part of the blade.
12. Never cut any piece shorter than the shortest possible length.
13. Never start cutting if the material is not firmly clamped by the vises.
14. Move the material only if the cutting bridge is completely up.

AIN COSTRUCTIVE CHARACTERISTICS
The machine uses :
• Cutting programmer CN015
• Trouble shutting control panel “Check Panel”
• Automatic feeding control device
• Blade speed controlled by an AC motor and a variable frequency drive.
• Working surface with non-wearable materials.
• Ball precision screws to control index movements.
• Vises with tempered inserts.
• Pressure reducer valves on vises.
• Self-positioning band guides.
• Carbide inserts mounted inside the band guides.
• Band brush powered by hydraulic motor.
• Chip conveyor powered by hydraulic motor.
• Cutting bridge mounted on chromate columns.
• Welded frame.
• Castings in gray iron C26
• Hydraulic band tension.
.
The saw is built to work in automatic also without an operator. A special design in the rear vise and working surface area allows the machine to cut slightly irregular bars.
2.2. B
LADE SPEED
The blade speed is controlled by an AC motor and a variable frequency drive, which allow to regulate the blade speed within
a range of 0- 100 m/1’. In this way the machine can cut both hard steels and aluminum. A digital reader constantly shows the
blade speed .
The blade speed can be adjusted :
• in automatic cycle during the editing ;
• in manual using a rotary potentiometer mounted on the control panel.
2.3. W
ORKING SURFACE
The material that has to be cut lays on a roller way that covers the entire stroke of the machine. The distance between the rollers is studied to avoid that short pieces can fall.
2.4. I
NDEXING
The material is fed by an index with hydraulic vises, which clamp the piece and move it under the blade. The index moves
on round chrome guides located underneath the roller table, and it is controlled by a tempered steel precision ball screw . The
index has two speeds : fast to move and slow to precisely position the piece. A rotary encoder (with a precision of a tenth of
a millimeter) controls the position of the index.

ISES
The saw vises are hydraulic. The clamping part of them have a tempered insert bolted. Besides, the hydraulic circuit that
controls the vises has a pressure reducer valve with a gauge to avoid to clamp with too much strength the material and deform it.
