Mitsui Seiki USA introducing 5-axis horizontal milling and turning machining center at IMTS

The HU63A-5XT 5-axis horizontal machining center from Mitsui Seiki USA is a high-precision millturn system that provides aerospace manufacturers with accurate milling and turning capabilities for complete part processing from roughing to finishing in a single setup.

The company says that this “virtually” ensures that even the most complex components are machined to spec the first time around.

The exceptionally accurate HU63A-5XT offers 900 mm X/Y/Z travels with simultaneous 5-axis machining capabilities and features a high-torque spindle delivering up to 1,081 Nm with +/-0.001 mm positioning accuracy.

Capable of machining hard-to-cut materials such as Titanium, the HU63A-5XT boasts cutting feed rates between 0.1 mm to 10,000 mm/minute in the X, Y and Z axes. Rapid traverse rates in the X axis can reach 12,000 mm/minute while the Y and Z axes travel up to 24,000 mm/minute. When combined with 2,160 degrees/minute for the A axis and 3,600 degrees/minute for the B axis, this millturn delivers unparalleled precision at considerable speeds.

This machining center, including two APCs and chip conveyor, measures 5,700 mm x 4,700 mm x 3,450 mm with pallet height ranging from 1,500 mm (APC side) to 1,480 mm (M/C side). Powered by the FANUC Series 501 iS-A controller, which is designed to work with high-speed complex multi-tasking machines such as this, the HU63A-5XT also performs drilling, boring, tapping and reaming operations offering shops a completely automated production operation in one machining powerhouse.

Additionally, this fully automated machining center is equipped with 630 mm square pallets with automatic pallet changer and automatic tool changer as standard.

“The HU63A-5XT represents Mitsui Seiki’s commitment to continuous innovation and delivering manufacturing solutions that keep our customers competitive in an increasingly demanding global market. By combining full 5-axis machining and turning capability in a single platform, manufacturers can complete complex components in one setup, reducing variation, improving throughput, and achieving the precision required for today’s most critical aerospace applications,” said Daniel Cleary, president and CEO, Mitsui Seiki USA.
