The Mitsui Seiki HU100A-5X is a high-performance horizontal machining center designed for precision and heavy-duty machining. It features a large 39.4" x 39.4" table capable of supporting workpieces up to 6,600 lbs, enhancing its suitability for substantial parts. The machine operates on five axes with travels of 51.2" (X), 47.2" (Y), 39.4" (Z), and rotary axes A1 and B1 providing 210° and 360° rotation respectively, enabling complex part geometries and multi-axis machining. The horizontal spindle is #50 taper, delivering up to 12,000 rpm with a 40 hp rating (30-minute duty), ensuring powerful and precise cutting performance for a variety of materials. A 60-tool automatic tool changer (ATC) supports efficient machining cycles with zero tool change chip time, optimizing productivity. Pallet handling is integrated as standard with a two-pallet changer allowing continuous operation and reduced downtime. The rapid traverse rates reach 590 ipm on the linear axes, facilitating faster positioning and cycle times. Overall, the HU100A-5X combines a robust work envelope, high spindle power, and comprehensive 5-axis control, making it ideal for complex, heavy, and precision machining applications within automotive, aerospace, and industrial manufacturing sectors.
