The new NDF 6870/70 multiple diamond wire cutter is a multi-wire machine designed to produce panels and plates of variable thickness from large blocks of granite and natural stone. This new unit represents the most modern technology in terms of the primary sawing of stone blocks, becoming the alternative to all traditionally used sawing methods, since it improves the productive capacity quantitatively, efficiently taking advantage of the necessary energy resources. for the production of materials and significantly reducing the production costs of the cutting phase.
The multiple diamond wire cutter is a machine that stands out for its efficiency and high productivity, designed to obtain high yields, characterized by its great robustness, thanks to its particular design that forms a compact, balanced and compensated unit where all the movements are concentrated, and its proven reliability and that of the elements that compose it, all of it being designed to withstand the harshest working conditions.
The main structure of the machine is basically made up of two robust columns made up of mechano-welded steel structures, connected to each other by an upper crossbar. The structure of the main frame is mounted on both columns, which joins the two handwheel-carrying carriages, which move vertically supported by both columns on linear guides with recirculating linear roller skates and driven by a pair of laminated spindles with recirculating nuts. balls, synchronized and activated by two motor-reducers with independent servomotors for the ascent/descent of the wires with a smooth and precise displacement, located in the upper part of both columns, the entire guide assembly is perfectly protected by PVC bellows .

The Ø1800 driving drum is made up of a single pulley with multiple channels with 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 diamond wires are also guided by two multi-channel drums that help to significantly reduce the deflection produced by them. At the end opposite the drive drum, the diamond wires rest on the set of idler pulleys, designed with a particular pivoting extraction system, which significantly reduces maintenance times.
Once the threads are located, they are adjusted with the active 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 them. each of the threads that are installed in the machine. The tensioning system manages to increase the useful life of the threads and therefore the profitability of the machine.

– 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.

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.

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.
SECURITY
NODOSAFER machines are protected by a security closure around their entire perimeter, complying with CE security regulations.
BLOCK TROLLEY
The machine has a motorized block carrier carriage incorporated as standard.

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
