Mitsui Seiki launches new Vertex 100 5-axis VMC

The Vertex 100 can machine workpieces 1,250mm in diameter and 850mm tall while occupying only 3m x 4.2m of shop floor space. X-Y-Z axis strokes are 1,000mm, 900mm, and 750mm respectively. Maximum swing diameter is 1,480mm.

From CAT 40 to HSK-A100 taper sizes the Vertex 100 is supplied with multiple spindle options (15,000rpm, 25,000rpm and 30,000rpm). A large 60-tool standard automatic tool changer handles maximum tool lengths of 300mm and maximum tool diameters of 125mm (CAT40/HSK A 63) or 160mm (CAT 50/ HSK A 100), offering maximum flexibility for job shop applications. Larger capacity tool changers are an additional option.

The machine’s tilt/rotary table, designed and built by Mitsui Seiki and supported by the rigid and robust cast iron base, provides high precision and rotation speed up to 100 rpm. The table’s C-axis motors are direct drive while the A-axis has tandem direct drive motors. The machine is capable of workpieces up to 1,250mm (49.25”) diameter.

The X- and Z-axes of the Vertex 100 are driven by single ball screws, with dual ball screws on the Y-axis. The linear axes are capable of fast, 1-G acceleration and deceleration. The machine’s Fanuc control features a state-of-the-art 375mm (14.75”) LCD HMI.

In addition to providing a large work envelope relative to the machine footprint, the Vertex 100 has numerous features that assure accuracy and consistency. The machine features a proprietary cast iron bed and a solid “box-in-box” design that provide superior rigidity, stiffness and agility. The innovative machine geometry results in positioning accuracy in the X, Y, and Z-axes of 0.001mm (0.000040”), ±6 arc seconds in A-axis, and ±4 arc seconds in the C-axis.

Hand-scraped guideways maximise precision. An advanced thermal compensation system assures size consistency, and glass scales provide minimum resolution of 0.001mm.

Robb Hudson, CEO, said: “The entire Vertex line of Mitsui Seiki machines is engineered for tight-tolerance work in mould and die, aerospace, energy, and other high precision component applications. The new Vertex 100 combines that precision with a compact configuration and larger workpiece capacity that enable users to greatly expand the range of parts they can productively process.”
