USED OKUMA MA-500HII

The OKUMA MA-500HII is a high-performance horizontal machining center engineered for precision, productivity, and reliability in demanding manufacturing environments. Built with a rigid cast-iron structure and Okuma’s advanced thermal stability design, the MA-500HII delivers excellent vibration damping and consistent dimensional accuracy during long production runs and heavy cutting operations. Its horizontal spindle configuration and pallet system improve chip evacuation and machining stability, making it ideal for continuous production and high-volume manufacturing applications.

The machine is equipped with a powerful high-torque spindle capable of handling a wide range of materials, including aluminum, steel, cast iron, and high-performance alloys. Controlled by Okuma’s OSP-P CNC system, the MA-500HII offers intuitive programming, fast processing speeds, and advanced features such as thermal compensation, collision avoidance, and automation integration. A dual-pallet changer system, large-capacity tool magazine, and fast rapid traverse rates help reduce idle time and maximize machining efficiency, while optional probing and automation systems enable unattended operation and process optimization.

The OKUMA MA-500HII is widely used in automotive, aerospace, and general engineering industries for producing complex and high-precision components such as engine blocks, transmission parts, and structural components. Its combination of horizontal machining efficiency, robust construction, and advanced control technology makes it a reliable and cost-effective solution for manufacturers seeking high productivity, consistent accuracy, and reduced cycle times in modern CNC machining operations.
