OKUMA LU4000 EX HORIZONTAL MACHINING CENTER

Technical Description

The Okuma LU4000 EX is a high-performance horizontal machining center designed for precision CNC turning and milling tasks. It features a main spindle capable of handling a maximum turning diameter of 18.9 inches and a turning length up to 49.21 inches, with a maximum swing of 27.36 inches. The spindle supports bar diameters up to 3.15 inches and operates at up to 4,200 RPM with 43 HP for the primary spindle and a secondary spindle at 4,000 RPM with 30 HP, enabling robust and flexible machining operations. The machine is equipped with dual turrets: an upper turret with up to 12 turning and rotary tools and a lower turret supporting 10 turning and rotary tools, allowing simultaneous use of two cutting tools for improved efficiency. The machine operates on 4 axes with travel ranges of 11.81 inches on the X axis (rapid traverse and max feed rate up to 984 IPM) and 29.13 inches on the Z axis (rapid traverse 984 IPM), providing precise and rapid positioning. Its structural design includes a 45-degree box way bed for rigidity and stability during heavy cutting. The LU4000 EX is suitable for complex, high-precision manufacturing applications across industries such as automotive and aerospace. It supports advanced multitasking capabilities and optional milling functions, making it a versatile solution for both mass production and custom work. The control system features modern OSP software with powerful CPUs for enhanced operability and processing speed, supporting seamless integration in modern CNC manufacturing environments.
