Overview

The DMG Mori NT 5400 DCG is a large-capacity turn-mill center in the NT DCG series, designed for heavy-duty 5-axis complete machining of large workpieces. The DCG (Driven at the Center of Gravity) box-in-box construction drives through the center of gravity of each axis slide, eliminating pitching moment during acceleration for superior dynamic accuracy on big, heavy parts where surface finish and geometric precision matter.

The main spindle delivers 45 kW (60 hp) at 3,000 RPM with 1,000 Nm of torque through an 18-inch chuck. The optional sub-spindle provides 37 kW (50 hp) at 3,500 RPM. Bar capacity is 127 mm (5 in). The turn-mill spindle runs at 12,000 RPM with 22 kW (30 hp) through an HSK-A63 interface, with 20,000 RPM optional.

The B-axis swivels through 240 degrees (plus/minus 120 degrees) via Direct Drive Motor. Axis travels are substantial: 780 mm (30.7 in) in X, 350 mm (13.8 in) in Y (plus/minus 175 mm), and 1,710 mm (67.3 in) in Z. Maximum turning diameter is 900 mm (35.4 in) with a turning length of 1,500 mm (59.1 in). Rapids hit 36 m/min on all main axes.

The standard tool magazine holds 40 stations, expandable to 80 or 120. An optional lower turret adds parallel processing. Control is Fanuc 31iB5 with MAPPS. The machine weighs approximately 24,000 kg (52,910 lb) and requires about 5,600 x 3,400 mm of floor space. Pricing starts around $750,000 with production configs running $900,000-$1,200,000.

Strengths & Limitations

Strengths

900 mm turning diameter handles large-diameter components that even the NT 4300 DCG cannot accommodate, including large flanges and housings
DCG box-in-box construction maintains superior dynamic accuracy despite the machine size, critical for surface finish on big parts
45 kW / 1,000 Nm main spindle delivers serious heavy-duty cutting power for deep roughing in large-diameter superalloys and hardened steels
22 kW turn-mill spindle is a step up from the NT 4300 18.5 kW, providing more milling capability for heavy cuts on large parts
350 mm Y-axis travel (plus/minus 175 mm) provides excellent off-center reach for complex milled features on large workpieces
127 mm (5 in) bar capacity covers the largest standard bar stock sizes for production work
Tool magazine expandable to 120 stations supports long unattended runs on complex large components

Limitations

Starting at $750K, this is a major capital investment that requires consistent utilization of large-part capabilities to justify
At 24,000 kg, foundation and rigging are serious undertakings adding $25,000-$40,000 to installed cost
3,000 RPM main spindle speed is the lowest in the NT series, limiting high-speed turning on smaller diameters
5,600 x 3,400 mm floor space requires dedicated machine bay with overhead crane access for loading large workpieces
Fanuc-only control; shops standardized on Siemens need to consider the CTX gamma series instead

Best For

Aerospace manufacturers producing large landing gear forgings, turbine discs, and structural housings up to 900 mm diameter Energy sector shops machining large turbine rotors, generator housings, and heavy valve bodies requiring 5-axis turn-mill capability Defense contractors running heavy artillery components, missile housings, and large cylindrical parts with complex milled features Oil and gas manufacturers producing large BOP components, Christmas tree valves, and downhole tools with complete machining needs Heavy industrial equipment shops machining large rolls, spindles, and bearing housings requiring DCG-level accuracy

Frequently Asked Questions

01 What does a DMG Mori NT 5400 DCG cost?

A new NT 5400 DCG starts around $750,000. Adding the 20,000 RPM milling spindle, sub-spindle, lower turret, expanded 120-tool magazine, and automation pushes to $900,000-$1,200,000.

02 What is the difference between the NT 5400 DCG and the NT 4300 DCG?

The NT 5400 DCG has larger turning diameter (900 mm vs 700 mm), longer turning length (1,500 mm vs 1,350 mm), more powerful spindles (45 kW / 1,000 Nm vs 37 kW / 700 Nm), larger chuck (18 in vs 15 in), wider Y-axis (350 mm vs 300 mm), and bigger bar capacity (127 mm vs 102 mm).

03 How does the NT 5400 DCG compare to the CTX gamma 2000 TC?

The NT 5400 DCG has larger turning diameter (900 mm vs 700 mm) and DCG construction. The CTX gamma 2000 TC has a mineral-cast bed, longer turning length (2,000 mm vs 1,500 mm), and runs Siemens. Choose based on whether you need larger diameter (NT) or longer length (CTX gamma).

04 What foundation does the NT 5400 DCG require?

At 24,000 kg, it requires a reinforced concrete foundation with 300-500 mm depth and vibration isolation. Budget $25,000-$40,000 for foundation work depending on existing floor conditions.
