OKUMA MA-400HA HORIZONTAL MACHINING CENTER

Technical Description

The Okuma MA-400HA is a 4-axis CNC horizontal machining center designed for high-precision milling operations. It features a work envelope with X, Y, and Z travels of 22 inches, 24 inches, and 24.6 inches respectively, accommodating a pallet size of 15.75 x 15.75 inches. Powered by a 20-horsepower spindle motor, it achieves speeds up to 15,000 RPM, driven through a CAT 40 taper. The machine is equipped with a 60-tool automatic tool changer, facilitating high-efficiency tool switching during complex machining tasks. It supports full 4th axis pallet indexing and has rapid traverse rates up to approximately 2362 inches per minute on all axes. The robust construction yields a total machine weight around 20,000 to 25,300 pounds and overall dimensions close to 177 inches in length, 95 inches in width, and 108 inches in height. Control is provided by the Okuma OSP-P200M CNC system, which includes advanced features like tool life management, spindle load monitoring, and coolant-through-spindle capability with high-pressure coolant delivery. Additional standard equipment often includes a chip conveyor, hydraulic pallet clamping, Renishaw probing, and magnetic filtration systems to enhance operational efficiency and precision. This machining center is ideal for industries requiring stable, accurate horizontal milling with automated tool handling and pallet indexing capabilities.
