Intelligent ROI is Makino technology package that works to reduce "non-cutting" time from part processing. For the a40 system, it involves a spindle that accelerates to 12,000 rpm in 0.5 seconds; 6,000-rpm rigid tapping speed; and 29% faster speed to full rapid traversal, which minimizes the cutting tools' feature-to-feature positioning time. The machine center also has Inertia Active Control technology, which optimizes the acceleration of multiple machine functions by evaluating and adapting fixture and tool weights. The a40 has a 400-mm pallet with a workpiece capacity of 630x900 mm (24.8x35.4 in./ DxH), meaning it is well proportion for a majority of diecast parts commonly machined in automotive and consumer products manufacturing. The machine's axis travels are 560, 640, and 640 mm (22.0, 25.2, and 25.2 in. / X, Y, and Z.) The maximum payload is 400 kg (880 lbs.)
