HU63A-5XT 5-Axis Machining Center Targets Aerospace Parts

Aerospace manufacturers producing engine cases and housings face tight repeatability requirements, where clamping errors across multiple setups can lead to mismatched components and scrap. Mitsui Seiki's HU63A-5XT is a 5-axis horizontal machining center that combines milling and turning capabilities, enabling complete part processing from roughing to finishing in a single setup.

The machine offers 35.4 in (900 mm) X/Y/Z travels with simultaneous 5-axis machining capability. A high-torque spindle delivers up to 797 ft-lb (1,081 Nm) of torque with positioning accuracy of ±0.00004 in (±0.001 mm).

It's capable of machining hard-to-cut materials such as titanium, with cutting feed rates ranging from 0.004 to 393.7 in/min (0.1 to 10,000 mm/min) across the X, Y, and Z axes. Rapid traverse rates reach 472.4 in/min (12,000 mm/min) in the X axis and 944.9 in/min (24,000 mm/min) in the Y and Z axes, while rotary rapid rates reach 2,160 deg/min for the A axis and 3,600 deg/min for the B axis.

The machining center comes standard with an automatic pallet changer using 24.8 in (630 mm) square pallets and an automatic tool changer, and it performs drilling, boring, tapping, and reaming operations. It's powered by a FANUC Series 501 iS-A controller designed for high-speed, multitasking operation.

Including two automatic pallet changers and a chip conveyor, the machine measures 224.4 x 185.0 x 135.8 in (5,700 x 4,700 x 3,450 mm), with pallet height ranging from 59.1 in (1,500 mm) on the APC side to 58.3 in (1,480 mm) on the machine side.
