Mitsui Seiki’s HU63-T five-axis CNC machining center is designed for power-generation applications, including critical rotating components such as blisks, impellers and turbine disks, as well as gas-turbine power-generation systems. Features include a work-diameter capacity ranging to 800 mm (31.5") on the vertically oriented table; work/fixture weight capacity of 300 kg (660 lbs); a variety of increased axis-stroke options; high-torque spindles (1,081 Nm – 800 foot-pounds continuous); a tuned structure for heavy cutting in hard metals; and a Fanuc 30iM control with enhanced features for five-axis simultaneous machining. The machining center’s XYZ working envelope measures 900 × 800 × 800 mm (35.4" × 31.5" × 31.5"). The rapid feed rate in X, Y and Z axes is 32,000 mm/min (1,260 ipm); positioning accuracy in X, Y and Z axes is 0.001 mm (0.00004"); and positioning repeatability is 0.001 mm (0.00004"). On the B axis, positioning accuracy is ±4 arcseconds and repeatability is ±1.5 arcseconds.
