Okuma MU-4000V VERTICAL MACHINING CENTER

Technical Description

The Okuma MU-4000V is a 5-axis CNC vertical machining center engineered for high-precision multitasking operations. Featuring a 15.75-inch square table and double-column construction, the machine delivers exceptional rigidity and thermal stability for demanding aerospace and die/mold applications. The standard spindle operates at 15,000 RPM with 30 HP (10-minute rating) and 22 kW continuous output, producing 199 N-m of torque, while optional high-speed spindles reach 20,000 or 25,000 RPM. The machine provides generous work envelope dimensions of 29.13 inches (X-axis), 18.11 inches (Y-axis), and 18.11 inches (Z-axis), with rapid traverse rates of 1,969 ipm across all three linear axes. The 5-axis capability includes simultaneous surfacing with rotary B-axis motion (±90° to -120°) and infinite C-axis rotation for complex geometries. A 32-position automatic tool changer with optional 48, 64-tool chain, or matrix configurations (up to 268 tools) delivers tool-to-tool efficiency. The machine accommodates workpieces up to 500 mm diameter with 400 mm height and maximum 300 kg weight capacity. Integrated with Okuma's OSP-P500 control system, the MU-4000V incorporates advanced features including Thermo-Friendly Concept for thermal compensation, Collision Avoidance System, and 5-Axis Auto Tuning System. Optional turning spindle capability at 1,200 RPM enables single-chuck multi-sided machining, maximizing productivity in complex part production.
