Mitsui Seiki’s HPX63 II 4-axis horizontal machining center, an improved version of the company’s proven HPX63 unit, features a 70-percent-faster rapid feed rate of 54 m/min that produces shorter cycle times, and a 14% reduction in shop floor footprint (now 5,554 x 3,530 mm) to maximize manufacturing facility space.
Capable of machining workpieces as large as 1,050 x 1,050 mm (diameter x height), the HPX63 II machining center is engineered to process medium-size precision parts. Pallet size is 630mm square and maximum table load is 1,200 kg. Positioning accuracy and repeatability are +/- 0.001 mm (one micron).
X, Y, and Z-axis strokes are 1,000, 800, and 900 mm respectively. An 18.5/15 kW (30 min./continuous) spindle utilizes ISO 7/24 50-taper tooling and provides rotation speeds from 15 to 6,000 rpm as well as 600 Nm maximum torque. The B-axis rotary table offers high torque and acceleration.
A 60-pocket automatic tool changer accommodates tools up to 500 mm long and 125 mm in diameter (265 mm diameter without adjacent tools), weighing up to 25 kg.
