HPX63 II 4-Axis Horizontal Machining Center

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

Capable of machining workpieces as large as 1,050mm in diameter x 1,050 mm hight, 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 1,000mm, 800mm and 900mm, respectively. An 18.5/15 kW (30 min./continuous) spindle utilizes ISO 7/24 50-taper tooling and provides rotation speeds from 15 rpm 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 toolchanger accommodates tools up to 500mm long and 125mm in diameter (265mm diameter without adjacent tools), weighing up to 25 kg.

“The HPX63 II represents the latest evolution of our company’s series of 630mm-pallet horizontal machining centers,” 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.”

  • automatic toolchanger

    automatic toolchanger

    Mechanism typically included in a machining center that, on the appropriate command, removes one cutting tool from the spindle nose and replaces it with another. The changer restores the used tool to the magazine and selects and withdraws the next desired tool from the storage magazine. The changer is controlled by a set of prerecorded/predetermined instructions associated with the part(s) to be produced.

  • centers


    Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.

  • feed


    Rate of change of position of the tool as a whole, relative to the workpiece while cutting.

  • machining center

    machining center

    CNC machine tool capable of drilling, reaming, tapping, milling and boring. Normally comes with an automatic toolchanger. See automatic toolchanger.

  • toolchanger


    Carriage or drum attached to a machining center that holds tools until needed; when a tool is needed, the toolchanger inserts the tool into the machine spindle. See automatic toolchanger.
