MITSUI SEIKI HS8A HORIZONTAL MACHINING CENTER

Technical Description

The Mitsui Seiki HS8A Horizontal Machining Center is engineered for high-precision, heavy-duty production, featuring a robust 59.1" x 59.1" table capable of supporting workpieces up to 17,600 lbs. The machine is equipped with a horizontal #50 taper spindle, delivering 49 HP (30-minute rating) and a maximum speed of 3,150 RPM, ideal for demanding machining applications. Tooling is managed by a 60-tool Automatic Tool Changer (ATC), expandable to 360 tools, with a rapid tool change time of 10 seconds. An optional pallet changer supports up to 6 pallets, enhancing throughput for high-volume operations. The HS8A provides 3 standard axes (X, Y, Z) with an optional 4th axis (B), offering travel distances of 70.9" (X), 59.1" (Y), and 47.2" (Z), and a full 360° B-axis rotation for complex part machining. All axes deliver a maximum feed rate of 158 ipm and rapid traverse speeds of 276 ipm, ensuring efficient cycle times. The machine’s rigid construction and high-capacity work support make it suitable for large, heavy, and intricate components, while its advanced tooling and automation options provide flexibility for a wide range of production requirements.
