MITSUI SEIKI HU100A-5XL HORIZONTAL MACHINING CENTER

Technical Description

The Mitsui Seiki HU100A-5XL is a robust 5-axis horizontal machining center engineered for heavy-duty precision machining. It features a large 39.4" x 39.4" table capable of supporting workpieces up to 6,600 lbs, optimized for large and heavy components. The horizontal spindle (#50 taper) delivers up to 12,000 RPM with a powerful 40 HP motor (30-minute rating), enabling high material removal rates with stability and rigidity. The machine incorporates a 60-tool automatic tool changer (ATC) for enhanced machining flexibility and productivity, along with a standard pallet changer system supporting two pallets to facilitate continuous production. Axis travels include an expansive X-axis travel of 78.74", Y-axis travel of 59.05", and Z-axis travel of 55.11", all with maximum feed rates of 394 IPM and rapid traverse speeds reaching 472 IPM, providing rapid and precise tool movements. The rotary axes offer full 210° (A axis) and 360° (B axis) rotation, enabling complex 5-sided machining and contouring. The design omits support rotary or index tables, emphasizing direct multi-axis control. This machining center is suited for precision, large-scale aerospace, automotive, and heavy equipment manufacturing, combining large workspace, powerful spindle capabilities, and advanced tool/pallet automation for high throughput and accuracy in complex part production.
