OKUMA MULTUS B-400II CNC LATHE

Technical Description

This is a high-performance 5-axis multitasking CNC lathe equipped with Okuma's OSP-P300S control system, designed for complex precision machining operations. The machine features a robust 15-inch chuck with 4.33-inch bar capacity and spindle bore, capable of handling substantial workpieces up to 60 inches in machining length. The main spindle delivers 40 HP with a speed range of 38 to 3,800 RPM, while independent live tooling provides 14 HP with speeds reaching 6,000 RPM for simultaneous milling and turning operations. The multitasking architecture accommodates a maximum 59.06-inch working distance between spindles, enabling complex part completion in single setups. Motion control includes full X, Y, Z-axis travel (27.17, 9.02, and 60.83 inches respectively), B-axis universal head rotation of 225°, and C-axis indexing with 0.001° precision for sophisticated geometry machining. Weighing 34,000 lbs, the machine demonstrates substantial structural rigidity necessary for precision work. The Okuma OSP-P300S control provides comprehensive, centralized data management through a user-friendly interface, incorporating Windows-based open architecture and an Intel Dual Core Processor for reliable program execution. This configuration enables operators to reduce setup times through shared database functionality while executing demanding 5-axis simultaneous machining tasks with smooth, accurate finishes on complex geometries.
