Overview

The DMG Mori NVD 4000 DCG is a compact vertical machining center that brings DCG (Driven at Center of Gravity) technology to the 400mm-class VMC segment, delivering production-grade accuracy and surface finish in a small footprint. The DCG drive system eliminates vibration at the source by aligning drive forces with axis mass centers, enabling high feed rates without sacrificing surface quality.

Travel measures 600 x 400 x 400 mm (23.6 x 15.7 x 15.7 in), positioning the NVD 4000 DCG for precision machining of smaller parts. Maximum workpiece dimensions reach 700 mm (27.6 in) length, 450 mm (17.7 in) width, and 400 mm (15.7 in) height at 350 kg (772 lb). The compact work envelope is optimized for die and mold components, medical parts, and precision production work.

The standard spindle runs at 12,000 RPM with options for 20,000 and 30,000 RPM for high-speed finishing and aluminum production. Die and mold specifications are included as standard, along with AI-nano high-precision contour control for exceptional surface finish on complex 3D surfaces. The machine builds on the Mori Seiki NV platform heritage known for rigidity and accuracy.

Rapid traverse reaches 50 m/min (1,969 ipm), faster than most VMCs in this class thanks to the optimized DCG drive kinematics. The MAPPS Fanuc control is standard. The NVD 4000 DCG targets die and mold shops, medical device manufacturers, and precision production environments where accuracy and surface finish are primary requirements. New machines price between $130,000 and $185,000. Specs sourced from DMG Mori published data.

Strengths & Limitations

Strengths

DCG drive technology delivers ±0.002 mm accuracy and exceptional surface finish at high feed rates
50 m/min rapids are 20-40% faster than most VMCs in this class, cutting non-productive time significantly
Die and mold specifications and AI-nano contour control are included as standard features
30,000 RPM spindle option enables true high-speed finishing for mold cavities and medical implants
Compact footprint fits into tight shop layouts while delivering production-grade precision
DCG vibration reduction extends tool life and improves surface quality compared to conventional drives

Limitations

400 mm Y and Z travel limits part size and depth capacity for larger workpieces
11 kW spindle power is conservative for aggressive roughing in steel and stainless
350 kg table load restricts fixture weight compared to larger VMCs
20-tool standard magazine is lean for complex multi-operation parts

Best For

Die and mold shops producing small to medium cavity inserts and core pins requiring exceptional surface finish Medical device manufacturers machining precision implants and instruments from titanium and stainless Precision production shops where ±0.002 mm accuracy reduces secondary grinding or EDM operations Electronics enclosure manufacturers needing flatness and perpendicularity beyond conventional VMC capability High-speed finishing cells where the 30K RPM option and DCG accuracy combine for mirror-like surface quality

Frequently Asked Questions

01 What does a new NVD 4000 DCG cost?

New machines start around $130,000 with the 12,000 RPM spindle. The 20,000 or 30,000 RPM spindle, expanded tool magazine, and probing push toward $160,000-$185,000. Used units from 2012-2020 trade for $60,000-$100,000.

02 NVD 4000 DCG vs NVD 6000 DCG?

The NVD 6000 DCG offers the same DCG technology with larger travel (600x500x500 vs 600x400x400 mm), higher table load (500 vs 350 kg), and a larger work envelope. Choose the 4000 for smaller parts where its compact footprint is an advantage.

03 How does DCG compare to box ways?

Different approaches to vibration management. Box ways absorb vibration through friction and mass. DCG prevents vibration from being generated by aligning drive forces with axis mass centers. DCG maintains higher feed rates while achieving similar or better surface finish.

04 What is AI-nano contour control?

AI-nano is Fanuc's high-precision contour control technology that uses look-ahead algorithms to optimize servo response during complex 3D surface machining. It reduces contour errors at corners and curved transitions, improving surface finish on die and mold work.
