Mitsui Seiki (USA)’s Vertex Hybrid G series of five-axis VMCs (models 55-5X, 75-5X and 100-5X) offer high speed, lights-out milling and grinding of die and mold, optical, and tooling components. The machines are capable of 0.0003" (7.5 µm) precision in 3+2 or simultaneous five-axis machining, and their main spindles rotate as fasts as 25,000 rpm. Air spindles enabling speeds ranging from 40,000 to 90,000 rpm can be changed via ATC.

Fanuc 3D volumetric compensation features enable volumetric calibration according to ISO10320-2 standards and the use of in-process 3D (NIST) traceable measuring capabilities. A part spinning process produces tangential planetary work spindle alignment, emulating the U-axis motion of jig grinding equipment. The machines can employ trochoidal dynamic power or high speed cutting strategies for tools rotating as fast as 90,000 rpm.

Key features include automatic, in-process grinding wheel dressing and size measurement and wheel calibration. Acoustic emission sensors and software-guided application strategies monitor milling and grinding process finishes.

The VMCs feature cast iron beds and a solid “box-in-box” design that contribute to rigidity, stiffness and agility. Positioning accuracy is 0.001 mm (0.000040”) in the X, Y, and Z axes, ±6 arc seconds in the A axis, and ±4 arc seconds in the C axis.

Hand-scraped guideways contribute to precision. A thermal compensation system facilitates size consistency, and glass scales provide a minimum resolution of 0.001 mm.
