Mitsui Seiki HPX63 HMC latest evolution

Mitsui Seiki’s HPX63 II 4-axis horizontal machining centre, an improved version of the company’s proven HPX63 unit, features a 70% faster rapid feed rate of 54m/min that produces shorter cycle times, and a 14% reduction in shopfloor footprint (now 5,554mm x 3,530mm) to maximise manufacturing facility space.

Capable of machining workpieces as large as 1,050mm x 1,050mm (diameter x height), the HPX63 II machining centre is engineered to process medium-size precision parts. Pallet size is 630mm square and maximum table load is 1,200kg. Positioning accuracy and repeatability are ±0.001mm (one micron).

X-, Y-, and Z-axis strokes are 1,000mm, 800mm, and 900mm respectively. An 18.5/15kW (30min./continuous) spindle utilises ISO 7/24 50-taper tooling and provides rotation speeds from 15rpm – 6,000rpm as well as 600Nm maximum torque. The B-axis rotary table offers high torque and acceleration.

A 60-pocket automatic tool changer accommodates tools up to 500mm long and 125mm in diameter (265mm diameter without adjacent tools), weighing up to 25kg.

“The HPX63 II represents the latest evolution of our company’s series of 630mm-pallet horizontal machining centres,” said Tom Dolan, Mitsui Seiki vice-president of sales and marketing, “Its improved performance and convenience illustrate the continuing efforts of Mitsui Seiki to help our customers increase their efficiency and competitiveness.”
