2 TECHNICAL DESCRIPTION

BAND SAWING MACHINE SteelX i 12 x 12 NC

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 stucks 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 mitre 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 liters
IT IS NECESSARY THAT CUSTOMER HAS A COMPRESSED AIR SYSTEM. AIR MUST BE FILTERED AND DECANTED. THIS SYSTEM WILL NOT BE SUPPLIED BY MTC or 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) (Optional, at extra cost)

The mitre positioning system is composed by the following elements:
• A large and accurate ball bearing, calculated to support and turn heavy loads, electrowelded between the support of the machine and its base, allowing the mitre positioning of the whole machine.
• Double chain welded in the perimeter of the turning crown.
• NC to control the mitre positioning.
There is a display that shows the mitre position.

The operator enters in the digital display the required different mitre positions and these values remain in memory.

Once the machine is positioned, the turning system is blocked automatically.

2.10 HYDRAULIC INSTALLATION

It is placed in the base of the machine with an easy access, reducing the maintenance time.

2.11 CONTROL AND MANAGMENT

All controls, both hydraulic and electric, are ergonomically placed on a single panel on one side of the cutting installation. The saw also has an additional portable control panel.

The protections of engines and auxiliary circuit are based on Thermo magnetics (no fuses), which allows rid repair if any of these protections trip.
