The 2006 Mori Seiki NH4000 horizontal machining center is a high-precision machine designed for advanced manufacturing applications. It offers substantial X, Y, and Z axis travels of 22 inches each, providing a versatile work envelope for diverse machining tasks. The spindle operates at speeds up to 12,000 RPM, supporting efficient high-speed cutting, and it uses a CAT 40 taper to accommodate a wide range of tooling. This model features an automatic tool changer (ATC) with a capacity of 120 tools, enabling flexible, uninterrupted machining operations and reducing manual setup time. Control is managed by the Fanuc MSX 501 IV CNC system, known for its reliability and precise control capabilities. The machine’s rigid construction, incorporating features such as the Box-in-Box structure and Driven at the Center of Gravity (DCG) technology, ensures excellent vibration control, thermal stability, and high accuracy during machining processes. Its robust design supports rapid feed rates and accelerations, optimizing productivity while maintaining surface finish and dimensional tolerances. Auxiliary features likely include coolant-through spindle for improved cutting performance and chip management systems to enhance operational efficiency. The NH4000 series is recognized for balancing a compact footprint with a large work envelope and high-rigidity construction, making it suitable for heavy-duty milling, drilling, and tapping in tool making, automotive, and aerospace industries. Overall, this machine combines versatile travel, substantial spindle capability, advanced CNC control, and extended tool capacity to meet demanding horizontal machining requirements effectively.
