Mitsui Seiki has evolved its popular "Vertex 750-5X" line of machines with new features and capabilities, and a broader range of options and configurations within the series. The new model series, comprising six distinct models, is now called Vertex 75X II. Linear axes (X, Y, Z) strokes are 750mm (29.5") x 800mm (31.4") x 700mm (27.5").
One of the key new features is an enhanced ultra high accuracy package. This option enhances Mitsui Seiki's existing, well-established construction techniques for accuracy and precision. As such, the Vertex line of machines are very well suited for tight-tolerance mold and die work, aerospace, energy, and other high precision component applications. Users can gain significant production improvements eliminating the traditional machine ‘warm up' time for very demanding precision jobs. Machine geometry is still unparalleled, and Positioning Accuracy in X, Y, and Z axes is 0.001mm (0.000040"). A-axis: ±6 arc seconds; C-axis: ±4 arc seconds.
In response to customer feedback and market demands, Mitsui Seiki now offers a new 30,000 rpm spindle with the Vertex 75X II, in addition to the 15,000,18,000 and 25,000 rpm choices. Customers can now take full advantage of the machine's acceleration and deceleration characteristics and high speed machining functions. An HSK-80 taper spindle connection (for those requiring more heavy-duty machining) is available as an option to compliment the existing HSK-63 and 40-taper tool interfaces.
The Vertex 75X II line includes several configurations in the range, based on table sizes and types from 225mm (9") to 500mm (19.7") diameter.
