Mitsui Seiki secures machining centre order

The HU100A-5XLL weighs some 67 tonnes, has a 2.5m between centre capacity on the A- and B-axis trunnion which is able to support components weighing up to three tonnes and will be used to machine large titanium airframe components.

Said 2D CNC Machinery director David Holden: “This machine breaks totally new ground in 5-axis machining for producing very large and complex aerospace components that have extremely demanding levels of stock removal in tough to machine material. The machine will also have to maintain high levels of accuracy both for geometric positioning and relationship of different features, size tolerance and surface finish.”

The HU100A-5XLL machining centre is the largest ever built by Mitsui Seiki in Japan. It will accommodate two pallets 1.7m by 1m using front ‘boxer' exchange which takes just 60 seconds, and incorporates pallet turn to assist loading. Axis strokes are 2.5m in X by 1.75m in Y by 1.4m in Z with duplex ballscrew drives to both the X- and Y- axes. The resolution through precision linear glass scales in X, Y and Z is 0.001mm and in the tilting +20 to -110 degree A-axis and rotary B-axis, 0.001 degree.
