– STRONG POINTS:
The multiple diamond wire cutter is a multi-wire cutter designed to produce slabs and boards of variable thickness from large blocks of granite and natural stone. Traditionally in granite transformation factories, the sawing of blocks is being carried out to the same size with looms when the blocks are large, or with large diamond disc block cutters in stonework workshops when semi-blocks are cut.
The greatest aspect to highlight is that the multi-wire cutter, for an equivalent capacity, the effective energy consumption is lower compared to any of the methods used. This translates into significant energy savings both in implementation and in production costs. This difference in equivalent energy savings is mainly due to the difference in sawing technology, the multi-wire saw only uses up to 70 or 72 loops of diamond wire and water during this process, cutting continuously. These diamond wires are basically made up of a steel cable covered by diamond rings along the cable, The cutting effect on the stone block to obtain the slabs and boards is produced by the effect of the continuous dragging movement of the threads at a linear speed of about 30 m/sec. combined at the same time with the rotation of the rings, producing a very high cutting power, a differentiated effect with respect to large traditional looms where the cutting process can be defined as the effect of a jigsaw, made up of a frame that houses about 100-130 strips of steel in contact with the stone blocks at the same time moving c in combination with the rain of abrasive mixture of water, steel shot and lime, which produces the same number of incisions in the stone block as quantity of strapping
The multiple diamond wire cutter is the alternative to the primary sawing methods currently used, improving the productive capacity quantitatively, efficiently taking advantage of the energy resources necessary for the production of materials and significantly reducing the waste produced during the cutting phase.
Comparatively, the advantages of using this new technology applied to the multi-wire cutter are evident. The multi-wire cutter can cut any type of stone material compared to the looms that only cut granite or marble, but they are two different models and use different tools, the looms are only profitable when they cut sheets of 2-3 centimeters in length. thickness, but its greatest disadvantage is in energy consumption and the very high production of solid waste, since the water used is recovered in all cases, this waste, apart from assuming a higher purification cost, presents a problem of environmental pollution in case of the looms since it contains iron, and the lime that alters the acidity of the waters, In addition, at the moment it is not possible to separate or recover at this stage of the process. Compared to traditional block cutters, there is an important difference that lies in the cutting height, with a disc we can cut 1.50 meters compared to the diamond wire that can cut any commercial block, apart from the great productive difference that exists.
The water treatment and purification process for this new process is therefore cheaper and less complex.
It is also worth noting that the water needs, although similar to the traditional loom, diamond wire cutting practically eliminates the need to wash the load after sawing, this being much less demanding and both the needs and the water losses during the cutting process are lower.
Another aspect to highlight is that the multi-wire cutter, for an equivalent capacity, the effective energy consumption is lower compared to any of the methods used. This translates into significant energy savings both in implementation and in production costs.
Regarding the consumables, to say that in the multithread cutter there is only one; the diamond wire, of small volume, easy storage and simple supply. The costs derived from storage, stock scheduling and handling are also lower than the strap, shot and lime, necessary for the traditional loom.
In reference to the implementation costs, in the first place the simplicity and the consequent lower cost of the civil works stand out, while in the loom the necessary work constitutes an indispensable part of it, in the multi-wire cutter, this becomes a mere support for it. In addition, in the case of renewal or replacement of the machine, the loom forces the new implementation to be exactly the same model as the previous one, while in the case of the multi-wire cutter there is a high degree of possibility of being able to adapt the existing civil works. In any case, it is important to say that the space occupied by the multiwire cutter is less.
The simplicity of the multi-wire cutter is significantly greater, both in installation, use and handling, as well as in maintenance, both in the mechanical and electrical aspects. It is important to note that the NDF-6870 multi-wire cutter does not use the common solution for vertical movement consisting of a central motor with gearbox, transmissions and angular gearboxes. This is replaced by two independent and electronically synchronized servomotors without coupling between them. This solution, in effect, eliminates the drawbacks of the classic mechanical transmissions, the gaps and possible breakage due to wear and fatigue, and also allows us greater flexibility in the movements to be carried out. In this aspect, it should be noted that the system is capable of working at speeds as slow as one millimeter per minute,
As a practical effect, the NDF-6840/35 cutter is the fastest machine on the market capable of performing a vertical upward movement in the face of any contingency, avoiding undesirable diamond wire marks on the stone.
The surface of the final product sawn with the diamond wire, in addition to the fact that it practically does not need washing, much less the use of acids or harmful chemical products that are dangerous to handle, offers the important advantage that its surface condition can be assimilated to a certain honed In the event that the material must be polished later, a certain reduction in costs associated with the abrasives used in the polishing process and the consequent reduction in production times should be noted.
The high speed of the multi-wire cutter will also allow new users of this technology to schedule production with less notice and greater flexibility than the loom, even allowing a block to be partially cut and the rest to be reserved for a more appropriate time. .
The flexibility of production is also given by the need for clearly lower staff. Preparing the saw on a string saw for a cut consumes less than half the time and less than half the human resources of a traditional strap loom.
With this cutting unit it is intended to integrate the fully automated operation of the primary sawing of stone blocks, with minimal human intervention and therefore a significant reduction in product handling maneuvers, regularization and optimization of the work processes, the increase in production capacity thanks to the reduction of cycle times and the efficient use of downtime, the reduction of energy consumption and the production of waste during the cutting process, and finally the reduction of the associated risks for the personnel involved in the handling and machining of materials throughout each working day.

– WHY BUY OUR CUTTING MACHINE:
The use of diamond wire in primary sawing work has been used in the sector for not many years, and said wire is applied on known machines, normally made up of two pulleys on which a wire is installed. forming a closed loop with which the cuts are made on the stone blocks.
In recent years, machines that use several diamond wires have begun to be used, which are mounted on drums with multiple channels or made up of several pulleys, on which several wires are mounted in order to make several cuts at the same time on the stone blocks, thus obtaining significant productions.
The machines used up to now present different technical problems when it comes to correctly tightening and controlling the loops of wire, in addition to another more significant one, which lies in the possibility of easily varying the position of the pairs of wires with in order to obtain different thicknesses or vary them in the production of boards.
Taking these disadvantages into account, the N.6870 cutter stands out for its simplicity in the device for individual tensioning of the tensioning wheels, and at the same time the variation of processing thicknesses in the slabs and boards to be cut has been simplified in a simple and easy.

– BLOCK TROLLEYS
The machine has TWO (2) standard built-in block carriers.

MULTIWIRE JUPITER GS220 is an open frame multiwire machine for the production of granite and marble slabs that performs blocks fast cutting through a set of diamond wires. It is available in several versions which differ for the maximum number of wires and for the diamond wire diameter (7,3 mm – 6,3 mm – 5,3 mm).
It stands out for its flexibility, reliability, state-of-the-art technical solutions and for its high production capacity.

The single line cutting system is a machine designed to cut rectangular blocks or granite slabs into large slab thicknesses. The device consists of a supporting structure with two flywheels, 2500 mm in diameter, which move the diamond wire for cutting. The speed of the wheels, and therefore of the rope, is variable and controlled by an inverter. The downward movement of the rope takes place by means of two roller carriages that move along a square column. This type of system allows high stiffness and, at the same time, very good smoothness. The rope tension is hydraulically regulated at constant pressure. The device can be equipped with fixed or rotating trolleys. They are always driven by a geared motor, controlled by an inverter and an encoder for precise positioning of the trolley.

The WIRE SAW is manufactured in 3 different versions (stationary, gantry on rails and dual i.e. stationary + gantry). The machine has been conceived for block cutting and squaring off thick slabs of sandstone, marble and granite.
The strong steel frame has been designed to ensure very high rigidity levels and precision during all the cutting phases. It is composed of two steel columns linked together by a steady connecting beam and two aluminium large size flywheel (Ø2150mm) reducing the diamond wire fatigue and also helping the wire spinning around its own axis, preventing its ovalization. The two flywheels move up and down on two columns thanks to 8 linear guides, granting the absence of vibrations, and maximising stability and unmistakable precision during the cutting phases.
The driving flywheel is powered by an 18.5kW asynchronous motor and its groups are moved by a screw & nut system that is driven by a brushless motor which is controlled by a drive that adjusts the working downfeed according to the diamond wire bow.

The multi wire saw machine abandoned the traditional linear roller system and fully adopted the precision linear slide to ensure the stable operation of the column linear slide during the processing. The adoption of the international new digital control technology has ensured the smooth operation of the machine. And the independent development tensioning system, PLC digital control system and modular combination of each part makes the machine has the advantages of simple structure, convenient operation, less occupied area, high efficiency, clean and environment protection. The machine is mainly used for granite, marble and the artificial stone slabs’ processing.



It is the recommended alternative equipment for gang saw machine. And due to a variety of specifications are available which will provide the possibility for the stone enterprises to process the large stone slabs and broaden the scope of application of the multi-wire saw machine.



This machine consists of the following main components: driving system, tensioning system, lifting system, trolley moving system, speed and pressure regulator system, sprinkler system, lubricating system, etc.

STRUCTURE AND DESIGN
The Multiple Diamond Wire Cutter N.6870/72 is a multi-wire machine designed to produce slabs and plates of variable thickness from granite and natural stone blocks.
The structure of the machine is basically made up of two robust columns made up of mechanically-welded steel structures, connected to each other by an upper crossbar. The structure of the flywheel-carrying main frame is mounted on both columns, which moves vertically supported by linear guides with
recirculating linear roller skates and driven by a pair of laminated spindles with recirculating ball nuts, synchronized and driven by two motors. -reducers with servomotors for raising/lowering the wires, located in the upper part of both columns, the entire guide assembly is perfectly protected by PVC bellows.
The entire machine is characterized by the robustness and reliability of the elements that make it up, all of it being designed to withstand the harshest working conditions, and in this aspect it is precisely where we can contribute all the experience accumulated over the years that we have been designing and manufacturing machinery for this sector.
MOTOR DRUM AND TAMBORINOS
The driving drum is made up of a single pulley with multiple grooves and connected to the main motor by means of a pulley and toothed belt transmission. The wires are positioned manually depending on the desired thickness, supported on one side of the machine on the drive drum, and in turn are tensioned from the opposite end by autonomous pulleys.
The drums, like the drive drum, are vulcanized, which increases their useful life and allows continuous work on the machine without delaying tire change downtimes. A movement in both directions of the tambourines allows the channel to be changed quickly and efficiently in the event that
a channel is excessively worn or a thread has not worked effectively. This method contrasts significantly with the change of tires that exists in other types of equipment since it significantly reduces the maintenance of the machine and allows work to be resumed in a considerably shorter period of time.
TENSIONING SYSTEM
The STA is a combination of tensioning systems patented by NODOSAFER that allows the useful life of the threads to be increased, also increasing profitability and guaranteeing optimum surface finishes.
The tensioning is characterized by the individual control of the deflection of each one of the threads, allowing the machine to automatically detect the arc described at all times and tend to equalize the horizontality of all the threads, so that the times block cutting completion times decrease and the consumption of the machine is uniform and balanced. This system also increases the useful life of each thread since, as significant arcs are not formed, all the threads work in a similar way without supporting excessive tensions.
The diamond wires are also guided by two small multi-channel drums that help to significantly reduce the deflection produced by them.
The Cutter N.6870/72 allows to cut a maximum of 2000 mm wide at 21 mm thick, allowing to obtain 71 sheets.
SYSTEM OF PULLEYS, TENSION PULLEYS AND FREE PULLEYS
Innovative pulley system, with pivoting extraction system, which considerably reduces maintenance times. The pulley change is carried out quickly and efficiently without having to disassemble the entire assembly, thanks to their design since with a small maneuver the desired set of pulleys is disassembled in record time.
Once the threads are located, they are adjusted with the tensioning device that acts individually on each one
of the tensioning pulleys, independently ensuring that each one of the threads has the same tension
regardless of the minimum differences in length that exist between each one . one of the threads that are installed on the machine.
HAIR COMB
CONTROL PANEL AND ELECTRICAL PANEL
In the electrical and control installation section, it is worth highlighting the installation of state-of-the-art automatons with programs custom designed by our technicians, so that the programming of the machine is as simple as possible, thus avoiding losses of unnecessary time. The programming of the work cycle and the visualization of its sequence is carried out on an operator terminal with a screen, where all the parameters of the cutting cycle are displayed.
A very intuitive and visual display and a radio control complete the maneuverability of the machine as well as the comfort for the operator to carry out his work safely and precisely.
VERSATILITY
The design of the N6870/72 allows, for everything described above, that the operation of the machine by the customer is very simple and intuitive. Each of the required parameters is controlled from the screen and when changing the thickness to be cut, the simple programming of the display indicates the position of each thread on the pulleys and drums without the possibility of error.

MULTIWIRE JUPITER GS220 is an open frame multiwire machine for the production of marble slabs that performs blocks fast cutting through a set of diamond wires. It is available in several versions which differ for the maximum number of wires and for the diamond wire diameter (7,3 mm - 6,3 mm- 5,3 mm- 4,3mm).

The multiwire machine of BM, the KODIAK EVOLUTION, is suitable for cutting granite blocks into slabs of various thickness. It is made in different size models, in order to install from 20 up to 84 diamond wires. The machine is exclusively constructed on 4 columns, guaranteeing the best stability and cutting precision. The machine can install diamond wires of diameter 7,3 mm, 6,3 mm and 5,3 mm. The tensioning of the wires is by a BM’s patented system, which guarantee the homogeneous independent tensioning of each diamond wire. The “triangle” structure allows the diamond wire to work only on 3 touching points, reducing to the minimum the stress of the wire during the work. The bigger diameters of the rollers and wheels, reduce the inclination angle of the diamond wire, extending so the life of the wire

Stationary multiple diamond wire saw to cut up to 34 slabs at the same time. Complete with a PLC and CNC system.

Multiwire saw with a big multi-groove drum (2.35 mt diameter) on the motor side and twenty big independent tensioning flywheels (2 mt in diameter), each tensioned by the patented Multipull system to manage at best the cutting conditions and optimize the life of the diamond wires. The plant is complete with a multi-groove guide drum (0.6 mt diameter) on the tensioning side to ensure further cutting precision. The motor drum, the tensioning flywheels and the guide drum are covered with replaceable multi-groove bands. A robust structure, composed by two rectangular section vertical columns, having high resistance to bending and torsion, grants high rigidity and maximum precision. The typical thicknesses of the slabs can be adjusted quickly without moving the flywheels. A special automatic comb device prevents any slabs movements during the cutting operations, avoiding their breakage and facilitating the exit of the wires after each cut. The control panel includes a PLC that controls the block trolley displacement after each cut, allowing an automatic sequence of cutting cycles.

A unique and patented feature of the POLYONE series consists of a special wire winding geometry that allows two cuts in the block for each diamond wire. With the POLYONE 20 version it is therefore possible to obtain 20 cuts in the block with 10 wires to realize 1 cm thicknesses, 14 cuts of 2 cm with 7 wires, and 10 cuts of 3 cm with 5 wires.

The compactness of the machine and its geometry allow a minimum need of manpower for the management of the wires, an optimized use of the diamond wire for each material, the 50% reduction of the devices necessary for the management of the wires and a consequent reduction of the maintenance costs.

The thickness change is quick through the correct positioning of the wires in the grooves of the guide-drums.

The diameter of the tensioning flywheels and of the motor flywheels is 1 m, while four 40 cm diam. independent guide groups assure the support for the maximum precision in the 2 cutting phases for each diamond wire.

Our slogan is "one shot, one block":
the machine has been in fact designed allowing to process in one single drop the maximum commercial block loadable on a truck, suitable for very high production.

The new plant is able to combine the flexibility shown so far in terms of various thicknesses achievable in the same drop and different materials allowed.

The opened machine structure is in fact constituted of two columns as the other units of the same range, and this solution, together with presence of covers, allows to get a very simple access to the inner motor grooved drum and single tensioning flywheels, optimizing the time necessary for several operations like the installation and replacement of diamond wires and their correct positioning in the grooves of the drum according to thicknesses to be realized.

The multiwire SW is definitely innovative both in appearance and performance. It is a machine with a two-column structure made using top-class solutions and components in order to provide the highest reliability standards.
