OKUMA MULTUS U4000 HORIZONTAL MACHINING CENTER

Technical Description

The Okuma Multus U4000 is a sophisticated 9-axis twin-spindle CNC lathe engineered for advanced multitasking operations combining turning and milling capabilities. Featuring dual main spindles operating at 4,200 RPM with 30 HP each and an optional sub-spindle, this machine accommodates workpieces up to 25.59 inches in diameter and 62.99 inches in length, with a maximum bar diameter capacity of 3 inches. The primary automatic tool changer accommodates 40 tools for turning operations, while the secondary turret provides 12 positions for additional tooling versatility. The machine excels in complex geometric machining through its 12,000 RPM H1 milling spindle with 30 HP and a 240-degree B-axis range, enabling simultaneous cutting with two tools and comprehensive contouring, deep drilling, and gear-cutting capabilities. The Y-axis provides 11.81 inches of travel for powerful off-center milling operations. Five-axis simultaneous motion delivers X, Y, and Z linear travels of 27.36, 11.81, and 62.99 inches respectively, with rapid traverse rates reaching 1,968 IPM. Equipped with Okuma's OSP-P300 CNC control featuring advanced collision avoidance and conversational programming, the machine delivers precision to 0.001 degrees. This configuration supports live tooling with full C-axis contouring on both spindles, streamlining production workflows while minimizing secondary operations and reducing machine-to-machine transfers.
