MORI SEIKI NH 4000 HORIZONTAL MACHINING CENTER

Technical Description

The Mori Seiki NH 4000 is a high-precision horizontal machining center designed for demanding manufacturing applications requiring exceptional stability, accuracy, and performance. Equipped with a 400mm square pallet working surface, this machine employs DCG (Driven at the Center of Gravity) technology to effectively control vibration, a critical factor in achieving high-speed and high-precision machining. The machine features a robust Box-in-Box construction that provides excellent rigidity and balance throughout its compact footprint. With 22.047 inches of travel on both X and Y axes and 24.803 inches on the Z axis, the NH 4000 delivers a large work envelope while maintaining a space-saving design that reduces required floor space by 11.1% compared to comparable machines. The spindle operates at a maximum of 14,000 RPM with 25 horsepower output, enabling high-speed cutting operations across diverse materials and applications. The CAT-40 taper spindle accommodates a 120-position automatic tool changer, facilitating rapid tool changes and minimizing production downtime during complex multi-operation workpieces. The machine achieves cutting feedrates up to 50 m/min with maximum acceleration of 0.6G on the X-axis, delivering outstanding productivity and surface quality. Advanced features include direct spindle cooling to minimize thermal distortion, superior chip disposal systems, and optional direct-drive motor technology for zero-backlash rotary indexing. These integrated capabilities combine to create a versatile platform suitable for precision milling, contouring, and complex component manufacturing across automotive, aerospace, and general industrial sectors.
