Diamond Wire Saw – Granfil Super Electronic
Diamond wire sawing machine for cutting granite equipped with a 50 HP electric motor and an inverter, which allows to vary the linear speed from 14 to 30m/sec.
The backward speed is controlled by the special electronic divide as a function of cutting stress, which values are pre-selected in order to keep a constant tensioning on wire and to stop the machine and flywheel rotation in case of malfunction or wire breakage.
Auxiliary motors controls a quick machine movement on rails for positioning the 360° rotation of main flywheel (diam. 960mm), lateral movement (stroke 500mm) and the device for the linear wire speed variation. A special device allows to increase greatly the torque during the start-up of diamond wire. The control panel, controlling all principal functions, can be positioned at a distance from the working area. The machine is supplied with 2 tracks of 3m length each.
The orientation and 360° rotation of the flywheel-holder head are mechanical and allows an easy and fast positioning of the machine as well as the execution of two parallel cuts at the maximum distance of 1900mm. The model GRAN FIL STANDARD has motorized the orientation and 360° rotation of the flywheel-holder head. In the GRAN FIL ELECTRONIC versions, an inverter permits the use of variable speeds.
