Wire Plant

The falcon diamond wire plants are a valid alternative to the traditional big disk, mono blade saw and gang saw.
The potential users of the plant are all those who have, or intend in future, to organise medium or large-scale productions for squaring blocks and slab cutting.
The advantages with the Falcon wire saw are:

  • Less power employed per each meter of cut, 30% less that traditional gang saw or big diameter disks.
  • The granite material cut does not require any particular washes (gang saw need it).
  • More even cutting surface, permitting saving of time and money in the slab polishing operations (the maximum tolerance of the final thickness of the slabs is +/- 0,5 mm)
  • High cutting autonomy, sufficient to allow for replacement of the tool after long period of time (gang saw need to replace blades every two cut).
  • Possibility of cutting very small size blocks, headers of highly irregular shape and blocks 2,1 meter tall: not possible on the big disk.
  • Reduced cutting stress, and and greatly reduced labour requirement.
  • Changes of cut thickness require only a few in comparison to the shot saw,
  • Very fast machine installation and very fast training of the people (2 weeks max including installation);
  • Small foundation work 20 to 60 m3 depending on the saw type;
  • Less impact on the environment as wire cutting produces less noise and vibrations.

The sludge produced by machines in cutting granite are free of both lime and iron, meaning that there is less special waste to dispose of.

Diamond wire saw for dressing and slabbing blocks

The machine is composed of a stiff metallic structure with box section beam and tubolar columns each with two “V” guides. The machine can carry flywheels of diameter either 2000 or 2500 mm. The machine is characterised by the following exclusive features desi­gned to maximise wire life, cutting precision and operator safety.

The machine uses only two large flywheels (diameter 2000 or 2500 mm) thus reducing wire fatigue and allowing the wire to rotate on its own axis during cutting: this in turn prevents the diamonds beads from developing an oval shape due to uneven wear.
Diamond wire tensioning uses one of the two flywheels, which travels 800 mm on a slide thanks to an hydraulic piston. This prevents localized stress on the diamond wire and allows the wire to be shortened if accidentally broken.
Electronic drop speed control.
The switchboard is separated from the machine, and includes a number of safety devices which stop the plant at the end of each cut, and in case of lack of water, low oil pressure or wire breakage .
The TOPversion is flitted with a stepless variable speed tran-smission to adapt the wire speed to the type of stone to be cut.
