Description

The A7 provides accuracy and reduced cycle times for large, complex aluminum monolithic structural parts.

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.
