The a61nx-5E five-axis horizontal machining center is built specifically for high-efficiency aluminum machining of small to mid-size, complex five-axis components and monolithic aerospace parts. Its design is based off of the widely successful nx-series machines. The a61nx-5E boosts productivity through the addition of twin direct-drive rotary axes for “one-and-done” efficiency. The a61nx-5E features an innovative automatic pallet changer design that directly loads the pallet into the 5th axis rotary table, while providing flat surface for ergonomic workpiece loading. Spindle options for the a61nx-5E range from the standard 14,000 RPM high-power spindle, to a remarkable 24,000 RPM, 80kW (duty rated) spindle for aluminum machining in aerospace. This under-race-lubricated, core-cooled spindle is capable of metal removal rates of up to 300 cubic inches per minute in the machining of aluminum. The a61nx-5E brings the metal removal and productivity of Makino’s MAG machines to a smaller platform, allowing aerospace manufactures to “right size” their parts production.
