Overview
The DMG MORI NVD 4000 DCG is a vertical machining center specified for die and mold work, with 600 × 400 × 400 mm (23.6 × 15.7 × 15.7 in) of travel, a 12,000 rpm spindle and 20,000 rpm or 30,000 rpm spindles as options. The largest workpiece is 700 mm (27.6 in) long, 450 mm (17.7 in) wide and 400 mm (15.7 in) high, up to 350 kg (771.6 lb).
Spindle speed is the main choice to make. 12,000 rpm covers general milling of mold bases and inserts. The 20,000 rpm and 30,000 rpm spindles are options, and they are what small ball-nose cutters need to reach a workable surface speed in hardened steel. DMG MORI's Highlights give no power, torque or taper for any of the three, so compare the spindle curves before settling on one, since a faster spindle usually has less torque at the low end.
Finishing programs for molds run for hours, and the machine is equipped for that. DMG MORI lists direct scale feedback on the X-, Y- and Z-axis, a separate-type coolant chiller and a separate-type oil cooler, and says the design concentrates on CNC control, positioning and measures against heat displacement. Scales measure the slide position itself, so ball screw growth during a long cycle does not end up on the part. AI-nano-high-precision contour control is a standard feature of the die and mold specification.
All of this sits on DCG drives, with which DMG MORI associates longer tool life, improved surface quality and roundness, and acceleration. The NV 4000 DCG shares the 600 × 400 × 400 mm travels and the 350 kg (771.6 lb) limit and accepts a 750 mm (29.5 in) long workpiece. The NVD 6000 DCG is the step up in size, with 900 × 600 × 450 mm (35.4 × 23.6 × 17.7 in) of travel.

Strengths & Limitations
Strengths
- Spindle speed of 12,000 rpm, with 20,000 rpm and 30,000 rpm spindles available as options
- Direct scale feedback for the X-, Y- and Z-axis
- Separate-type coolant chiller and separate-type oil cooler
- AI-nano-high-precision contour control is a standard feature of the die and mold specification
- DCG drives, which DMG MORI associates with longer tool life and improved surface quality and roundness
Limitations
- The 20,000 rpm and 30,000 rpm spindles are options
- No spindle power, torque or taper is stated for any of the three speeds
- Workpieces are limited to 350 kg (771.6 lb), which restricts the size of mold base that can be loaded
- Z travel of 400 mm (15.7 in) has to cover tool length as well as cavity depth

Frequently Asked Questions
01
DMG MORI lists a maximum spindle speed of 12,000 rpm, with 20,000 rpm and 30,000 rpm as options. No power, torque or taper is given for any of them in the Highlights. Choose by the smallest cutter you run regularly: the smaller the tool, the more speed it needs to cut properly.
02
Its standard die and mold specification includes AI-nano-high-precision contour control. Around that, DMG MORI lists direct scale feedback for the X-, Y- and Z-axis, a separate-type coolant chiller and a separate-type oil cooler, all aimed at heat displacement during long programs, plus the optional 20,000 rpm and 30,000 rpm spindles for small finishing tools.
03
Up to 700 mm (27.6 in) long, 450 mm (17.7 in) wide and 400 mm (15.7 in) high, with a maximum weight of 350 kg (771.6 lb). Travels are 600 mm (23.6 in) in X and 400 mm (15.7 in) in Y and Z. Cavity depth and tool length together have to fit inside the Z travel.
04
Hardly at all. The NV 4000 DCG has the same 600 × 400 × 400 mm (23.6 × 15.7 × 15.7 in) of travel and the same 350 kg (771.6 lb) workpiece limit, and accepts a workpiece 750 mm (29.5 in) long. The NVD 4000 DCG takes 700 mm (27.6 in). The choice between them rests on equipment, not envelope.
05
The NVD 6000 DCG, with 900 mm (35.4 in) of X, 600 mm (23.6 in) of Y and 450 mm (17.7 in) of Z travel. Against the 600 × 400 × 400 mm of the NVD 4000 DCG, that is a much larger table area and a small gain in Z.
