MITSUI SEIKI HU100A-5XLL HORIZONTAL MACHINING CENTER

Technical Description

The Mitsui Seiki HU100A-5XLL is a high-performance horizontal machining center designed for heavy-duty precision machining with a 5-axis configuration. The machine features a robust 39.4" x 39.4" worktable capable of supporting workpieces up to 6,600 lbs, enabling large and heavy component fabrication. It utilizes a horizontal spindle with a CAT #50 taper, delivering up to 12,000 rpm and 40 HP (30-minute rating), ensuring ample power for a variety of milling operations. The 5-axis capability includes linear travels of 98.42" (X), 68.89" (Y), and 55.11" (Z), alongside rotary axes A with 210° and B with full 360° rotation for complex geometries and multi-sided machining. Tool management is facilitated through a 60-tool automatic tool changer (ATC), with zero-second tool change chip time, maximizing productivity by minimizing downtime. The machine includes a standard pallet changer supporting two pallets for efficient workpiece setup and changeover. Rapid traverse rates reach 374 inches per minute across X, Y, and Z axes to reduce non-cutting time. The system does not include a support index or rotary table, focusing on rigid direct machining capabilities. This model is engineered to deliver accuracy, rigidity, and versatility in machining large, complex workpieces common in aerospace, automotive, and heavy manufacturing sectors.
