MITSUI SEIKI HS6A HORIZONTAL MACHINING CENTER

Technical Description

The Mitsui Seiki HS6A is a horizontal machining center designed for robust and precise metalworking applications. It features a large work table measuring 39.4 x 39.4 inches, capable of supporting workpieces up to 4,400 lbs. The horizontal spindle has a CAT #50 taper with a standard maximum speed of 4,500 RPM, optional upgrade to 8,000 RPM, and 25 HP power at a 30-minute rating, offering substantial machining capability for medium to heavy-duty operations. The machine supports 3 axes with travels of 51 inches (X), and 39.4 inches (Y and Z), all capable of rapid traverse speeds up to 591 inches per minute, enabling efficient movement and reduced cycle times. Tool handling is managed by a standard 32-tool Automatic Tool Changer (ATC) with a quick 11-second tool change time, and an optional expansion up to 270 tools enhances flexibility for complex jobs. The machine offers options for rotary table support and pallet changers, with 2 pallets standard and expandable to 10, facilitating higher throughput and reduced downtime. While the primary configuration features three axes, a 4-axis option is available to increase machining versatility. The Mitsui Seiki HS6A combines a sturdy structure, substantial table load capacity, moderate high-speed spindle capability, and expandable tooling and automation options, making it suitable for demanding manufacturing environments requiring a reliable and adaptable horizontal machining platform.
