OKUMA MA-12500H HORIZONTAL MACHINING CENTER

Technical Description

The Okuma MA-12500H is a high-performance horizontal machining center designed for heavy-duty and large workpieces. It features a 49.21" x 49.21" rotary pallet table supporting up to 11,100 lbs, with a support rotary table standard and no support index table. The machine operates with a 50 taper horizontal spindle capable of 6,000 rpm at 60 HP (30-minute rating), with optional configurations including a 4,500 rpm heavy-duty spindle or a high-speed HSK-A100 option. It incorporates a 177-tool automatic tool changer (ATC) and a standard 2-pallet changer for efficient automation. The machine travels 86.61" in X, 64.96" in both Y and Z axes, with a rapid traverse rate of 1,653 ipm, and offers a full 360° B-axis rotary table, supporting complex 4-axis CNC operations. The MA-12500H is built on an integral rib-reinforced bed with Okuma’s Thermo-Friendly Concept, ensuring excellent thermal stability and machining accuracy. High torque and power spindles enable precise and efficient machining of aluminum, cast iron, titanium, Inconel, and other difficult materials. The large tool magazine and fast tool change capabilities optimize productivity for demanding aerospace, automotive, and mold manufacturing applications. The machine is equipped with advanced CNC control, collision avoidance software, high-pressure coolant (including thru-spindle), and an integrated chip conveyor for sustained high-throughput performance.
