Breton Bestwire 2 axes - Besides squaring blocks and cutting slabs, this machine performs shaping operations with two interpolated axes

BESTWIRE 2 AXES SHAPING MACHINE
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 inverter 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 pairs of wire-driving pulleys installed next to the point where the wire gets into, and comes out from, the block to be sawn. 

Lubrication

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 sys-tem through sensors, which detect the position of the stretching piston.

Positioning accuracy of the block-holding trolley

The block-holding trolley (on request) 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 screen and user-friendly software ensure a simple programming, control 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.

Device to move the slabs 

with vertical motorized positioning, provided with pneumatic cylinder that moves the slabs after they have been cut, thus maintaining the wire deflection set on the prefixed value.

Ortobreton 4EG - Multiblade cutting system for granite block with independent strip extractor

Ortobreton 4EG - portal block saw

Maximum rigidity to increase performances and minimise running costs 

Portal machine 

The circular blades are positioned on the machining area by shifting the block platform. 

Superframe structure

Two columns on each side of the spindle support beam provide greater rigidity.

The improved geometry minimises vibrations 

The portal block saw is the ideal solution for limiting the vibrations. Each circular blade works in ideal conditions and cutting accuracy is excellent.  

4EG block saws enhance the portal layout by means of two columns on either side of the machine. 

The portal structure enables the horizontal blade to be easily incorporated into the solid structure of the machine. The horizontal blade detaches the strips whilst the vertical ones operate.

SUPERFRAME structure     
The 4EG block saws are a real point of reference as to rigidity and stability of the cutting system.

The superframe structure provides the solidity required by a blade pack wider than one meter.

Each end of the spindle beam is rigidly fixed to two columns.

The structure acts against twisting of the spindle beam even when thrusts have a transversal component.

Vertical movement of the beam is provided by a reduction gear that transmits movement to the four angular transmissions connected to the four screws so as to ensure precise positioning.

Cutting is thus very precise, even in critical conditions, e.g. when only one side of the blade pack is working.

Unit for integrated horizontal cutting     
In the Ortobreton 4EG SFO block saws, the horizontal cutting unit is connected to the main structure of the machine but is independent from the vertical blades: this allows the unit to remove the strips while vertical blades cut the next series.                             

In this way the machine is always running, thereby ensuring greater productivity.

The horizontal blade unit slides on the two front columns and has very precise movements.  

The horizontal blade works in synchronism with the automatic vacuum unloader that moves to the right position so as to pick up and support the strip before it has been completely detached. 

The overhead structure of the unloader minimises the space occupied on the ground and enables very rapid cycles that are much less than the time required to detach the strip.

A machine designed to minimise running costs 

The running costs of a block saw are mainly due to the cost of diamond tools. The annual expense for tools may be as great as the amount invested in the machine. 

Wear of the diamond tools depends, besides on the rigidity of the machine structure, also on how the spindle carriage travels. In the 4EG model, an asynchronous motor controlled by an inverter that actuates a pair of parallel racks meshed to two pinions, moves the spindle-holding carriage. 

A dynamically balanced, large-sized spindle shaft performs the blade rotation.  In the 4EG 1100 SFO, the diameter is 210 mm and the moment of inertia is almost four times that of a shaft with diameter of 150 mm. This great moment of inertia means that the spindle shaft flexion is minimal even under heavy-duty conditions with 60 blades applied.

The unit for moving the platform into the machining area 

A rugged steel guard protects the screw in an oil bath that conveys the platform to the machining area. 

A labyrinth seal prevents water from coming into contact with the screw, which is moved by an inverter-driven motor. 

The platform reaches its working position with great precision by running on a flat and a prismatic rail. 

Management system with personal computer in Windows environment

The work of the block saw must be programmed very carefully. To increase the operator’s concentration, the machine is managed by a personal computer where a user-friendly software facilitates all operations. 

The data on block dimensions can be easily acquired by positioning the machine’s work axes using the palmtop keypad.

The personal computer can be connected to the Breton remote assistance service, which can rapidly acquire the information on machine status in order to carry out a rapid diagnosis and if necessary proceed directly with a software operation. 

Numberless statistics regarding operating time and tool duration can be processed. The programme also warns the operator when it is necessary to carry out a scheduled maintenance job.

Breton high-duty resin-treating plant

Since 1991 SIRMERSAN Marble Industry Inc. (Cinnah Cad. 46/3, Cankaya, Ankara, Turkey) has been producing and exporting top quality marble blocks, slabs and tiles and has now become one of the largest producers of travertine with 3 quarries and 2 production sites.
In 2002, SIRMERSAN began marketing a prestigious beige marble quarried in Yesilova with the brand "White Pearl".SIRMERSAN factory is located in Denizli, the Turkish heart of marble quarrying.

A Breton automatic cutting line for marble and/or travertine slabs will start operating in September 2013. A scanner reading the slab surface and software for cut optimization (suitable even for slabs with irregular surface and inner defects) will be installed at the forepart of the line.
The line will produce tiles, strips and panels with the desired dimensions with top efficiency and precision.

A new Breton slab resin-treating plant will start producing in February 2014: it is indeed the plant with the highest production capacity ever installed in the world, capable of processing one net-reinforced slab which is resin-treated on both sides every 55 seconds.

This mega plant is fully automatic and includes six 40-level kilns, a vacuum chamber and two stations for resin mixing and spraying.

The following are its distinguishing features:
1. slabs are directly loaded from the gangsaw trolley and it is possible to handle them in the "diamond-match" pattern
2. double drying and catalysis kilns in order to ensure a cycle time of 55 seconds/slab (net-reinforced on one face and resin-treated on both faces).
3. the resin-treating and netting operations are performed automatically
4. user-friendly operational software on colour touch-screen
5. plant with a reduced encumbrance: approx. 700 m2.
Well, that’s all for today.
