AIN COSTRUCTIVE CHARACTERISTICS
The machine uses :
• Cutting programmer SAWIII
• 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 al-
lows the machine to cut slightly irregular bars.

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.

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 roll-
ers 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.
