The hallmark of the MA-12500H-W is its ability to provide a good balance of speed and cutting power for machining difficult-to-machine materials, cast iron and aluminum alloys. This makes it well-suited for large-part aerospace machining. The W axis allows for a longer tool stroke to machine complex, difficult-to-reach part features. It has a maximum tool length of 1,100 mm. At IMTS 2016, the MA-12500H-W will be shown with the new W-axis option and in skeleton form. It will feature a cutting simulation of a steel construction frame.
