OKUMA MA-8000H HORIZONTAL MACHINING CENTER

Technical Description

The Okuma MA-8000H is a high-performance horizontal machining center featuring a 4-axis configuration and a horizontal spindle orientation optimized for versatility and precision. It offers a substantial tool magazine capacity of up to 400 tools, enabling extensive job flexibility and reduced tool change frequency. The machine boasts maximum travels of approximately 55.12 inches (X-axis), 47.24 inches (Y-axis), and 53.15 inches (Z-axis), with rapid traverse rates reaching 1,969 inches per minute across all three axes, ensuring fast and efficient movement. The worktable measures 31.50 by 31.50 inches, supporting large and heavy workpieces up to 72,600 lbs. Equipped with various spindle options, the MA-8000H accommodates spindle speeds from 50 to 12,000 min⁻¹ with power outputs ranging from 30 kW up to 45 kW, matching a broad spectrum of machining demands from heavy-duty steel cutting to high-speed aluminum machining. Okuma’s proprietary Thermo-Friendly Concept minimizes thermal deformation via a double sleeve spindle cooling system, maintaining accuracy under changing temperatures and heavy workloads. Additional features include cast-in ball screw mounts for stable, predictable positioning, advanced chip evacuation systems, and a sludgeless coolant tank design to reduce maintenance and improve coolant efficiency. Designed for automation compatibility, it integrates seamlessly with APC systems, FMS, and robotic solutions to enhance productivity. With a maximum workpiece diameter of 57 inches and a rotary pallet size of 31.5 inches square, the MA-8000H is engineered for large-scale, high-precision manufacturing environments demanding reliability, accuracy, and throughput efficiency.
