Featuring a net driving force that acts through the center of the axis, Mori Seiki’s NV4000 DCG vertical machining center is designed to increase performance while minimizing vibration. The machine has five ballscrews—two on the Y axis, two on the Z axis and one on the X axis. According to the company, this setup reduces vibration without sacrificing speed for accuracy. For extra rigidity, the product’s design allows machining forces to traverse across the arch-shaped column and through the bed to form a closed loop.
The machine features an ATC chip-to-chip tool-changing time of 2.8 seconds, a tool-to-tool time of 1 second and a work envelope of 23.6" × 15.7" × 15.7". It comes with a 40-taper spindle with 12,000 rpm and 25 hp. An optional 20,000 rpm spindle is also available. A center-trough design evacuates chips, even when cutting dry.
