Feature

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.
