An April, 2013 event Makino hosted at its U.S. headquarters in Mason, Ohio highlighted solutions for effective production of aerospace structural components. The event featured a number of machining demonstrations of both aluminum and titanium components.
 
One example of what it calls “right size” machines for small structural components is the a61nx-5E. This is a 24,000-rpm five-axis horizontal machine built on a 500-mm HMC platform. At the event, it was machining an aluminum landing edge segment, demonstrating one-shot wall finishing, high speed floor finishing and material removal rates as high as 300 cubic IPM. The machine features an atypical pallet changing system for its twin, direct-drive rotary tables that brings effective ergonomics to five- axis machining. This video shows a pallet change whereby a vertically fixtured pallet is removed from the workzone, rotated 180-degrees and presented horizontally to an operator. At the same time, the opposite pallet on the opposite rotary table is loaded into the machine.

    Lockheed Martin’s precision machining of composite skin sections for the F-35 provides part of the reason why this plane saves money for U.S. taxpayers. That machining makes the plane compelling in ways that have led other countries to take up some of the cost. Here is a look at a high-value, highly engineered machining process for the Joint Strike Fighter aircraft.
