MITSUI SEIKI HU40-T HORIZONTAL MACHINING CENTER

Technical Description

The MITSUI SEIKI HU40-T is a 5-axis horizontal machining center designed for precision high-production applications in aerospace, automotive, and medical industries. This machine features a robust table-on-table design with integrated B-axis and C-axis rotary tables, enabling simultaneous multi-axis machining for complex geometries with fewer setups. The work envelope spans 24.05 inches (611 mm) in the X-axis, 22.124 inches (562 mm) in the Y-axis, and 27.95 inches (710 mm) in the Z-axis, accommodating medium to large-scale components. Powered by a 30 horsepower spindle motor with maximum speeds reaching 15,000 RPM, the machine delivers the cutting force necessary for efficient material removal across aluminum, brass, stainless steel, and titanium. The machine is equipped with a Fanuc 15M CNC control system, a 240-position automatic tool changer, and a 60-station automatic pallet indexing system for unattended production capabilities. Notable features include pallet and 5th axis table indexing precision of 0.001 degrees, a #40 spindle taper, and high-speed rotary axes offering unprecedented indexing speeds. The sliding headstock with direct spindle drive technology minimizes maintenance while ensuring spindle accuracy, supported by a double-outline, 3-node rigidity system ideal for 3D machining operations. A standard coolant system manages chips and debris during high-speed operations, while an automatic spindle protection device safeguards against over-speed conditions.
