Breton Paragon

Multiwire machine for sawing stone blocks

Multi diamond wire machine to saw slabs in thicknesses of 20 mm, 30 mm, or more.
The structural robustness combined with the characteristic triangle system makes it possible to saw marble and granite blocks to make slabs of various thicknesses.

Reasons why

  • Various thickness slabs: 20, 30, 40, 50 mm or more
    1

    Various thickness slabs: 20, 30, 40, 50 mm or more

    Breton Paragon can saw slabs of different thicknesses, from the classic 20 and 30 mm sizes up to high thicknesses of 40 and 50 mm or more. This is possible due the availability of two gauge zones, one zone dedicated to all three thicknesses and a second zone dedicated exclusively to the 20 and 30 mm thicknesses.

  • Isosceles triangle geometry to extend the wires lifetime

    Isosceles triangle geometry to extend the wires lifetime

    The exclusive structure of Breton Paragon allows the use of wires with length restricted to 20 metres, thus guaranteeing lower levels of vibration of the wires during the cut with consequent improved sawing quality and longer duration of the rubber profiles.
    The tension wheels, one for each wire, running on bearings, are each controlled by a single hydraulic piston to guarantee uniform and constant tension on each wire.

  • Load-bearing structure optimised to cancel vibrations

    Load-bearing structure optimised to cancel vibrations

    The wheels and tensioners are mounted in a strong closed steel frame which runs along the load-bearing columns, firmly anchored to the ground and stabilized with steel tie rods to guarantee the total absence of warping that could prejudice cutting performance. Deformation of the columns during sawing operations was assessed with finite element mathematical calculations.

  • Simple and safe wires installation

    Simple and safe wires installation

    The range of movement of the tension wheels is generous, thus allowing the cutting wires to be installed quickly and easily, while all forms of complex pretensioning systems have been eliminated.
    The system of ladders and walkways allows the operator to install the wires with ease. The drive and idle wheels are easily accessible and protected by a practical sliding housing. The valves to disable tension wheels when not in use are located on the upper walkway in a convenient position for the operator.

  • High quality rubber profiles

    High quality rubber profiles

    The polyurethane profiles are made in Breton's automatic plant by means of a casting process (rather than extrusion); this means they feature multidirectional reticulation of the polyurethane molecules to produce enhanced resistance to wear. Each profile is dimensionally checked by automatic devices and a dimensional check is performed by the operator on a samples basis.
    The system makes it possible to cut with a 5.3 mm thick wire, thus reducing cutting kerf.

The new generation triangle solution

Robust and accurate multiwire machine

Paragon was designed to minimise vibration during the cutting phase and guarantee the maximum precision in wire positioning in order to minimise wastage of material.

The isosceles triangle construction geometry, combined with the one metre diameter rollers, make it possible to optimise efficiency of the wire in contact with the material or in the free sections, reducing while also guaranteeing very high traction. The system with 5 rotary units is composed of the tension wheels unit, 2 low guide wheels, the drive wheel and the idle wheels set.

The high performance of the machine has tangible results in terms of production, wire lifetime, and maintenance of cutting positions. Also, with the “adjustable guide wheels”, also with small blocks, you can always use the machine in the best conditions in terms of the tangential direction of sawing.

Technical views

Technological highlights

  • Linked to the main motor to transmit all the necessary power and, with its 1000 mm diameter, ideal to avoid stressing the wire.

    / 01
    Drive wheel

  • Independent motorised positioning of the guide wheels is available as an optional feature. The guide wheels can be positioned close to the block (60 cm). This increases the quality of the resulting cut and brings the sawing structure vertical movement speed to the maximum values.

    / 02
    Independent and motorised lower guide wheels

  • Each wire runs on an independent wheel that makes it possible to offset even minor length variations or stretching, which can otherwise cause different peripheral speeds with consequent damage of the rubber profiles or negative repercussions on the wire.

    / 03
    Idle wheels set

  • The blend of the rubber profiles for Breton multiwire machines was developed by the BIT to guarantee the maximum performance and appropriate lifetimes to reduce routine maintenance times. The profiles are made in-house on a proprietary plant so Breton maintains absolute technological control of the process.

    / 04
    Rubber profiles designed and produced in house
