DMG Mori NT 4300 DCG vs DMG Mori NT 5400 DCG
DMG Mori vs DMG Mori · Mill-Turn Machines
Summary
The DMG Mori NT 4300 DCG and the DMG Mori NT 5400 DCG are mill-turn machines in two sizes. The DMG Mori NT 5400 DCG is the larger machine on every row of the table: longer travels, larger bar and longer workpieces.
It has 1,040 x 510 x 2,140 mm (40.9 x 20.1 x 84.3 in) of X/Y/Z travel against 750 x 420 x 1,650 mm (29.5 x 16.5 x 65 in), takes 103 mm (4.1 in) bar against 90 mm (3.5 in), and holds workpieces up to 1,921 mm (75.6 in) long against 1,498 mm (59 in). The DMG Mori NT 4300 DCG wins no row here; its case is fit, for chuck and bar work that stays within its envelope.

Advantages
DMG Mori NT 4300 DCG
- Sized for bar-fed turn-mill parts up to 90 mm (3.5 in) in diameter
- Covers shafts up to 1,498 mm (59 in) long without stepping up to the larger machine
DMG Mori NT 5400 DCG
- 1,040 mm (40.9 in) of X travel against 750 mm (29.5 in)
- 510 mm (20.1 in) of Y travel against 420 mm (16.5 in) for off-center boring and milling
- 2,140 mm (84.3 in) of Z travel and 1,921 mm (75.6 in) workpiece length against 1,650 mm (65 in) and 1,498 mm (59 in)
- 103 mm (4.1 in) bar capacity against 90 mm (3.5 in)
Verdict
Buy the size the parts need. The DMG Mori NT 5400 DCG is the choice for large-diameter chuck parts, stocky shafts and housings that need 1,040 mm (40.9 in) of X, 510 mm (20.1 in) of Y or workpieces up to 1,921 mm (75.6 in) long. The DMG Mori NT 4300 DCG is the choice when bar stays within 90 mm (3.5 in) and shafts within 1,498 mm (59 in), because the extra capacity of the larger machine would then go unused.
