Machine Comparison
DMG Mori NT 4250 DCG vs DMG Mori NT 4300 DCG
DMG Mori vs DMG Mori · Mill-Turn Machines
Summary
The DMG Mori NT 4250 DCG and the DMG Mori NT 4300 DCG are sister mill-turn machines with identical axis travels: 750 x 420 x 1,650 mm (29.5 x 16.5 x 65 in) in X, Y and Z. They differ in bar capacity and in the longest workpiece each takes.
The DMG Mori NT 4300 DCG takes larger bar, 90 mm (3.5 in) against 80 mm (3.1 in). The DMG Mori NT 4250 DCG takes a slightly longer workpiece, 1,542 mm (60.7 in) against 1,498 mm (59 in). The table for this pair covers travels, bar capacity and workpiece length only, so those two rows are the whole comparison.
Specifications Comparison
| Specification | DMG Mori NT 4250 DCG | DMG Mori NT 4300 DCG |
|---|---|---|
| X-Axis Travel | 750 mm (29.5 in) | 750 mm (29.5 in) |
| Y-Axis Travel | 420 mm (16.5 in) | 420 mm (16.5 in) |
| Z-Axis Travel | 1,650 mm (65 in) | 1,650 mm (65 in) |
| Bar Capacity | 80 mm (3.1 in) | 90 mm (3.5 in) ▲ |
| Max Workpiece Length | 1,542 mm (60.7 in) ▲ | 1,498 mm (59 in) |
Advantages
DMG Mori NT 4250 DCG
- 1,542 mm (60.7 in) maximum workpiece length against 1,498 mm (59 in)
- Full 750 x 420 x 1,650 mm travels for shops whose bar stock stays within 80 mm (3.1 in)
DMG Mori NT 4300 DCG
- 90 mm (3.5 in) bar capacity against 80 mm (3.1 in)
- Covers larger bar stock without giving up any X, Y or Z travel
Verdict
Choose on stock size. If bar-fed parts run above 80 mm (3.1 in), the DMG Mori NT 4300 DCG is the machine, with 90 mm (3.5 in) bar capacity. If the work is shafts near the length limit, the DMG Mori NT 4250 DCG takes 1,542 mm (60.7 in) against 1,498 mm (59 in). For everything else the published travels are identical, and the table gives no further reason to prefer one.
