LGR4-1SI INVERTER machine was built for marble, granite and stones cutting of marble, granite and stones; it has gone a solid structure and high quality elements, suitable for big and especially difficult cutting.
The machine is equipped with inverter in order to change the speed of the diamond wire from 0 to 40 mt/sec and with a towing device to change the tension load on the wire. The inverter allows to regulate the speed of the diamond wire during every cutting phase and to obtain a gradual starting and stop. It is ideal for hard and abrasive materials and for very big and especially difficult cutting.
The machine is equipped with a forced ventilation system with filtering air in order to reduce the exercise temperatures of the inverter.
Thanks to a total rotation (360°) of the flywheel unit and to different lateral and vertical shifting, it is possible to execute different kinds of cutting:
2 360° rotation movements
- 2 horizontal movements (total amplitude: 1,80 mt towards right and towards left)
2 vertical movements (total slide from earth: 50 cm)
The transfer and rotation movements are realized by an hydraulic power unit, while the shifting movement is due to chromate tubes and bronze bushes slipping. Rotation movements proceeds by a steel/bronze gear ring hydraulic engine and a steel worm. Machine slipping is realized by a geared motor, cogged drive wheels and a slot tracks, that allow to execute cuttings till 25% maximal slope, guarantying an high stability of the machine during the operations.
The machine may be supplied with different engines 50/60/75 Hp.
Lochtmans’ diamond wire cutting machines are equipped with accident prevention system in order to avoid risks for workers who operate or work near the machine, because the breaking of diamond wire can create projection of circuit elements (matchboards, spacers, springs or parts of cable) and the consequent whip action of the cable. LGR4-1S machine is equipped with a very practical and functional protection system.
Thanks to the protection racket and to a simple movement, it can be possible to set the fillet protection device in any positions of the flywheel engine(360°), without removing the protection system.
The protection device is extensible and it can reach all the open path of diamond wire, also when the machine is in motion. While the machine is moving the screen belt lets off covering the area where the diamond wire goes open, being an effective element of protection. Hydraulic tension and rewind of the band.
