USED OKUMA MB-4000H

The OKUMA MB-4000H is a high-performance horizontal machining center designed for precision, reliability, and productivity in demanding manufacturing environments. Built with a rigid cast-iron structure and Okuma’s advanced thermal stability design, the MB-4000H delivers excellent vibration damping and consistent dimensional accuracy during long machining cycles and heavy cutting operations. Its horizontal spindle configuration improves chip evacuation and machining stability, making it ideal for continuous production and high-volume manufacturing applications.

The MB-4000H is equipped with a powerful high-speed and high-torque spindle capable of machining a wide range of materials, including aluminum, steel, cast iron, and high-performance alloys. Controlled by Okuma’s OSP-P CNC system, the machine offers intuitive programming, fast processing, 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 speeds help minimize idle time and maximize machining efficiency, while optional probing systems and automation solutions support unattended operation and process optimization.

The OKUMA MB-4000H is widely used in automotive, aerospace, and general engineering industries for producing complex, high-precision components such as engine parts, transmission components, and structural assemblies. 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.
