Well-suited for die/mold applications, NVD4000 DCG VCMs incorporate

five ballscrews — two on the Y, two on the Z, and one on the X — that reportedly reduce vibration without sacrificing speed for accuracy. Input increments of 0.1 µ increase machine resolution, and all three axes have direct-scale feedback for accuracy in constant-running applications. There is dynamic thermal displacement control for the machine’s 40-taper spindles, which are powered by 25-hp motors delivering 12,000 rpm.
