MITSUI SEIKI HS6A-5X HORIZONTAL MACHINING CENTER

Technical Description

The Mitsui Seiki HS6A-5X is a high-performance 5-axis horizontal machining center designed for heavy-duty precision machining. It features a large 39.3" x 39.3" table capable of supporting up to 4,400 lbs, with a standard support index table and an optional rotary table for enhanced workpiece positioning flexibility. The machine’s horizontal spindle employs a #50 taper with a peak speed of 4,500 RPM, upgradable to 10,000 RPM, delivering 20 HP with a 30-minute rating, suitable for a broad range of materials and cutting applications. This center boasts a 32-position automatic tool changer (ATC), with an option to expand to a 270-tool capacity, and a tool change time of 12 seconds, facilitating high productivity and minimal downtime. Optionally, the system can be equipped with a pallet changer supporting 2 pallets standard, expandable to 10, optimizing workflow for batch or continuous production. The machine provides substantial travel ranges: X-axis at 51.18", Y-axis at 47.24", and Z-axis at 39.7". It includes five axes with rotational capabilities of 120° on the A-axis and full 360° on the B-axis, enabling complex part geometries and multi-angle machining in a single setup. Rapid traverse and max feed rates are optimized for efficiency though specific values are not listed. Overall, the HS6A-5X delivers a robust solution for machining large, heavy, and complex parts with flexible tooling and workholding configurations suitable for aerospace, automotive, and heavy industrial components.
