DMG Mori CTX 350 vs DMG Mori CTX 350 4A
DMG Mori vs DMG Mori · CNC Lathes
Summary
The DMG Mori CTX 350 and the DMG Mori CTX 350 4A share a platform: both take 65 mm (2.6 in) bar, both have 100 mm (3.9 in) of Y travel, and both run the main spindle to 5,500 rpm and the second spindle to 6,000 rpm. Workpiece length is nearly the same, 540 mm (21.3 in) against 530 mm (20.9 in).
The differences are in the travels and the layout. The CTX 350 has more X travel, 250 mm (9.8 in) against 185 mm (7.3 in), and more Z, 550 mm (21.7 in) against 495 mm (19.5 in). On the CTX 350 the 6,000 rpm counter spindle is an extra-cost option; the CTX 350 4A lists a right spindle at that speed and is built to cut with two turrets at once.
Specifications Comparison
| Specification | DMG Mori CTX 350 | DMG Mori CTX 350 4A |
|---|---|---|
| X-Axis Travel | 250 mm (9.8 in) ▲ | 185 mm (7.3 in) |
| Y-Axis Travel | 100 mm (3.9 in) | 100 mm (3.9 in) |
| Z-Axis Travel | 550 mm (21.7 in) ▲ | 495 mm (19.5 in) |
| Bar Capacity | 65 mm (2.6 in) | 65 mm (2.6 in) |
| Max Spindle Speed | 5,500 rpm (main spindle ISM65) | 5,500 rpm (left spindle, ISM 65) |
| Sub-Spindle Speed | 6,000 rpm (optional counter spindle ISM 50) | 6,000 rpm (right spindle, ISM 50 Plus) |
| Max Workpiece Length | 540 mm (21.3 in) | 530 mm (20.9 in) |
Advantages
DMG Mori CTX 350
- 250 mm (9.8 in) of X travel against 185 mm (7.3 in)
- 550 mm (21.7 in) of Z travel against 495 mm (19.5 in)
- Suited to chuck parts as well as bar work, with the counter spindle left as an option
DMG Mori CTX 350 4A
- Two turrets cutting at once to reduce cycle time
- 6,000 rpm right spindle listed as part of the machine, where the CTX 350 counter spindle is optional
- Suited to 6-sided complete machining of bar-fed production parts
Verdict
Same bar size and spindle speeds, different jobs. Choose the DMG Mori CTX 350 for mixed chuck and bar work, where its 250 mm (9.8 in) of X and 550 mm (21.7 in) of Z travel give more room and a counter spindle can be added if needed. Choose the DMG Mori CTX 350 4A for bar-fed series production, where two turrets working at once and complete machining on both spindles cut the cycle time per part.
