The A7 is designed with extended X-, Y- and Z-axis travels of 7,000 mm, 2,500 mm and 1,000 mm), respectively, to accommodate part sizes up to 7,000 mm by 2,000 mm by 700 mm, and 5,000 kg. The machine’s extended Z-axis travel provides increased side-face machining efficiency for improved productivity and capability. New linear motors in the X-axis produce thrust forces of 30,000N for acceleration rates up to 0.5G, further increasing productivity through reduced cycle times.
Featured in the A7 is Makino’s new patent-pending Volumetric Accuracy Compensation technology for improved tool-tip positioning accuracy. This technology provides in-process tool-tip corrections for sustained dynamic accuracy even in complex three-dimensional geometries in parts up to seven meters.
The A7 is equipped with a 33,000-rpm HSK-F80 spindle with high-power output of 107 HP (80 kW). At peak power output, the A7 spindle produces chip-removal rates up to 5,400 cc/min.
