DMG Mori CTX gamma 3000 TC vs DMG Mori NT 4250 DCG
DMG Mori vs DMG Mori · Mill-Turn Machines
Summary
The DMG Mori CTX gamma 3000 TC and the DMG Mori NT 4250 DCG are both mill-turn machines with 420 mm (16.5 in) of Y travel for off-center milling on turned parts. The headline difference is length: the DMG Mori CTX gamma 3000 TC takes workpieces up to 3,000 mm (118.1 in), nearly twice the 1,542 mm (60.7 in) of the DMG Mori NT 4250 DCG.
Z travel follows the same pattern, 3,050 mm (120.1 in) against 1,650 mm (65 in). The DMG Mori CTX gamma 3000 TC also passes larger bar, 127 mm (5 in) against 80 mm (3.1 in), and has a little more X travel, 800 mm (31.5 in) against 750 mm (29.5 in). The DMG Mori NT 4250 DCG leads on none of the published rows and matches the longer machine only on Y travel.
Specifications Comparison
| Specification | DMG Mori CTX gamma 3000 TC | DMG Mori NT 4250 DCG |
|---|---|---|
| X-Axis Travel | 800 mm (31.5 in) ▲ | 750 mm (29.5 in) |
| Y-Axis Travel | 420 mm (16.5 in) | 420 mm (16.5 in) |
| Z-Axis Travel | 3,050 mm (120.1 in) ▲ | 1,650 mm (65 in) |
| Bar Capacity | 127 mm (5 in) ▲ | 80 mm (3.1 in) |
| Max Workpiece Length | 3,000 mm (118.1 in) ▲ | 1,542 mm (60.7 in) |
Advantages
DMG Mori CTX gamma 3000 TC
- Workpieces up to 3,000 mm (118.1 in) long against 1,542 mm (60.7 in)
- 3,050 mm (120.1 in) of Z travel against 1,650 mm (65 in)
- 127 mm (5 in) bar capacity against 80 mm (3.1 in)
- 800 mm (31.5 in) of X travel against 750 mm (29.5 in)
DMG Mori NT 4250 DCG
- Sized for shafts up to 1,542 mm (60.7 in) and bar up to 80 mm (3.1 in), where the longer machine's capacity would go unused
- Suited to turned parts with prismatic features milled off-center and to contours cut with simultaneous 5-axis moves
Verdict
Part length decides this. Long shafts, spindles and rolls beyond 1,542 mm (60.7 in), or bar above 80 mm (3.1 in), need the DMG Mori CTX gamma 3000 TC with its 3,000 mm (118.1 in) workpiece length and 127 mm (5 in) bar capacity. For shorter turned parts with prismatic milled features, the DMG Mori NT 4250 DCG offers the same 420 mm (16.5 in) of Y travel, and the longer machine's capacity would go unused.
