TECHNICAL DESCRIPTIONS
BAND SAWING MACHINE i27x19nc-40 ( i 700 x 440 LMGS)
1.1 BAND WHEELS
Bandwheels are 27" Diameter to maintain proper clearance and minimize twist
Blade Tracking is automatic
Bandwheels are of open spoke design for chip removal

2.1 COLUMNS AND BOW
Bow is made in electro welded and stabilized steel.
Bow and main column are filled in with concrete polymer.
Bow is supported on two hydraulic cylinders and it is guided in twin prismatic columns.
The Saw Head guiding along the columns is made by high performance lineal guides in the main
column, and by support bearings in the secondary column, so that any friction between bow and
column is practically avoided, once blade is tensioned.
Blade’s inclined disposition allows aggressive cutting rate to the square surfaces of profiles and
bundles, so that the very varying cutting section is equilibrated.

2.2 AUTOMATIC BLADE TENSIONING
Automatic blade tensioning by means of a hydraulic
cylinder. This hydraulic cylinder tensions the blade until a
prefixed value, keeping always the correct blade
tensioning. It has a pressure switch which looks after the
correct tensioning and it relaxes the blade when machine
is waiting, guaranteeing in this way a lower blade wear. If
blade breaks, machine stops automatically.

2.3 BLADE GUIDING
Blade lateral guiding is made with a combination of bearings and hard metal plates allowing
any readjust of blade's position.
Blade's upper guiding is made by bearings, one at each guiding arm, avoiding any cutting
vibration and reducing the noise level during the cut.
The guiding arm is driven by a hydraulic cylinder till the position where the mobile clamp is, so it is not
necessary any manual adjustment of the mobile arm to the piece width.
During the cut process, the mobile arm is blocked by hydraulic pistons.

2.4 SAW DRIVING
High performance gearbox specially oversized to support
high work loads at low revolutions.
Electronic frequency inverter to control the blade speed
change.
Material axle treated and amply sized, assembled over a
double line of bearings.
Security blade stop system when blade stuck into the
material.

2.5 DOWNFEED AND PRESSURE
Downfeed and pressure are controlled by a varying flow valve, with compensation for different oil and
a pressure regulating valve.
By proper regulation of both valves is achieved a precise feed rate.

2.6 FASTENING CLAMPS
The horizontal clamping of material is made on both sides of the blade and the material remains fully
bound until the cut ends.
By changing from miter cut to straight cut or vice versa is not necessary to adjust the position of the
clamps, because when the machine rotates, the stationary clamp remains in the direction of the
material.
The fix clamp is grooved and tempered in order to avoid premature wear.

2.7 COOLING: AIR–OIL MIXED SPRAY
Environment friendly lubrication system.
System is composed by several pipes that allow the arrival
of the lubrication oil to the directional projection pipes that
act in the cutting area.
The oil dropping is intermittent with the possibility of
increasing or reducing the dropping frequency depending
on need.
Main technical features of the system are:
Exit flow 3-30 mm3/ impulse(variable).
Lubricant deposit: 2 litters
IT IS NECESSARY THAT CUSTOMER HAS A
COMPRESSED AIR SYSTEM. AIR MUST BE FILTERED
AND DECANTED. THIS SYSTEM WILL NOT BE
SUPPLIED BY INDOTECH.

2.8 BLADE CLEANING
Is performed using a rotating brush, driven by an
electric motor, allowing rapid readjustment as the
brush wears.

2.9 NC MITRE POSITIONING (+45º,-60º)
The miter positioning system is composed by the following elements:
 A large and accurate ball bearing, calculated to support and turn heavy loads, electro welded
between the support of the machine and its base, allowing the miter positioning of the whole
machine.
 Double chain electro welded in the perimeter of the turning crown.
 NC to control the miter positioning.
There is a display that shows the miter
position.
The operator enters in the digital display the
required different miter positions and these
values remain in memory.
Once the machine is positioned, the turning
system is blocked automatically.
