Gantry Type G Series
Starvision G Series Gantry type machining center features large capacity including X travel from 6 to 36 meters and is possible to enlarge to 60 meters, Y travel from 2 to 5 meters and Z travel selection is 1, 1.2 and 1.5 meters. Large workpiece machining used to take a lot of time and Starvision is determined to improve the efficiency. For the transmission system, we use German gear reducer and rack and pinion linear motions which deliver 30m/min in rapid feed rate. With twin servo motors operate synchronously, we are able to eliminate the backlash and achieve an optimal precision. G series perfectly combines speed and precision to achieve the ideal efficiency and is well regarded for large workpiece machining, shipbuilding industry, vacuum equipment machining and railway industry.

※All specification are subjected to change without prior notice.
(1) Floor type table can be tailor-made according to customer's foundation for extra large or heavy workpiece machining demand.
(2) Machine floor space (L) varies with different X axis travel of the machine.
(3) Machine weight varies with different X axis travel of the machine. The weight listed is based on 6 meter models, and it increases by approximately 10 tons with every 2 meters lengthened in X axis.
