Vertical Machining Center Offers More Accurate Contouring

The NV4000 vertical machining center is said to give users the ability to contour more accurately, accelerate among positions faster and experience less residual vibration. Using a design concept called Driven at the Center of Gravity (DCG), the net driving force acts through the center of the axis. The machining center contains five ballscrews,­ two on the Y-axis, two on the Z-axis and one on the X-axis, that enable a reduction in vibration without sacrificing speed for accuracy.
