Breton EASYWIRE 

MACHINE STRUCTURE AND MECHANISMS

Heavy-duty, heat treated arc-welded steel structure ensuring the required stiffness of the system and cutting precision of the machine.
2 opposite carts sliding vertically on the columns of the support structure for the vertical motion of the cutting wire. The carts support the components for the wire motion and stretching, and are moved vertically by screw/nut screw mechanisms, which are con-trolled by asynchronous motor.
Driving pulley for wire rotation, with a diameter of 1.000 mm. The wire is actuated by an inverter controlled asynchronous motor that manages the wire peripheral speed according to the material to be sawn.
Wire stretching pulley with a diameter of 1.000 mm, which is kept constantly under tension by a pneumatic cylinder.
2 independent driven pulleys with a diameter of 1.000 mm.
2 pulleys with a diameter of 350 mm, whose function is to drive the wire next to the point where it gets into, and comes out from, the block to be sawn.
PULLEY COATING
All pulleys are provided with a wire driving groove, which is coated with special interchangeable wear-resistant elastomer profiles.

SAFETY MEASURES
Sensor connectd to the stretching cylinder that detects promptly any possible breakage of the wire and stops the machine.

DEFLECTION CONTROL
During the sawing operation, the wire deflection is managed by the machine control system, which adjusts the down-feed according to the position of the stretching piston.
RAILS FOR BLOCK-HOLDING TROLLEY
The machine is provided with 8 metres of rails for the sliding of the block-holding trolley in the machine working area.
LUBRICATION
Manually operated lubrication system supplying the lubricant.
MACHINE PROGRAMMING
Control unit for the programming, control of the cutting cycle and management of the working axes.
Software with efficient and user-friendly operator interface.
Colour touch-screen for interaction with the operator.

MACHINE STRUCTURE AND MECHANISMS

Heavy-duty, heat treated arc-welded steel structure ensuring the required stiffness of the system and cutting precision of the machine.
Two opposite carts containing the components for the wire motion, slide vertically along the machine columns by means of screw/nut screw mechanisms, thus moving the wire up and down.
The wire is rotated by a large diameter driving pulley, which is actuated by belts and in-verter controlled asynchronous motor, in order to optimize the wire peripheral speed according to the material to be sawn.
Another large diameter driven pulley is constantly kept under tension by a pneumatic cylinder, thus giving the wire the ideal tension.
The mechanism is completed by two upper, independent driven pulleys and two wire-driving pulleys installed next to the point where the wire gets into, and comes out from, the block to be sawn.

LUBRIFICATION
A manually operated lubrication system provides lubricant to critical points.

PAINTING

In order to ensure a high corrosion strength, both the structure and the components are first sand-blasted to prepare the surface before painting, then coated with a zinc-based epoxy primer and lastly with a second bi-components top coat.

PULLEY COATING

All pulleys are coated with special, interchangeable, wear-resistant elastomer profiles.

SAFETY MEASURES   

A special sensor, connected to the stretching cylinder, detects any possible breakage of the wire and stops the machine instantly.

AUTOMATIC ADJUSTMENT OF THE WIRE LOWERING   

When cutting, the wire lowering speed is automatically managed by the machine control system through sensors, which detect the position of the stretching piston.

POSITIONING ACCURACY OF THE BLOCK-HOLDING TROLLEY   

The block-holding trolley has four motorized wheels, which are installed on rugged bearings. Wheels are provided with a special profile acting as a guide along the rails that are fixed to the foundations so as to obtain a perfect parallelism. The system ensures an accurate positioning of the trolley and a precise parallelism of cuts, thus enabling to cut slabs (even thick slabs) with the precision typically required by this type of operation.

PROGRAMMING

The colour touch-screen and user-friendly software ensure a simple programming, con-trol of the cutting cycle and management of the working axes. A mobile button panel makes the activation of the main working axes easier for the operator.
