DMG Mori CTX 350 4A vs DMG Mori CTX 450
DMG Mori vs DMG Mori · CNC Lathes
Summary
The DMG Mori CTX 350 4A and the DMG Mori CTX 450 are both turning centers, built around different priorities. The CTX 350 4A is a two-turret machine for bar-fed production parts; the CTX 450 is the larger machine for chuck parts and shafts.
The CTX 450 is bigger on every size row: 310 mm (12.2 in) of X travel against 185 mm (7.3 in), 825 mm (32.5 in) of Z against 495 mm (19.5 in), 130 mm (5.1 in) of Y against 100 mm (3.9 in), a 102 mm (4 in) bar capacity against 65 mm (2.6 in), and workpieces up to 800 mm (31.5 in) long against 530 mm (20.9 in). The CTX 350 4A spins faster: 5,500 rpm on the left spindle against 4,000 rpm, and 6,000 rpm on the right spindle against 5,500 rpm on the CTX 450 counter spindle.

Advantages
DMG Mori CTX 350 4A
- 5,500 rpm left spindle against 4,000 rpm on the CTX 450 main spindle
- 6,000 rpm right spindle against a 5,500 rpm counter spindle
- Two turrets cutting at once for shorter cycle times on bar-fed parts
DMG Mori CTX 450
- 102 mm (4 in) bar capacity against 65 mm (2.6 in)
- Workpieces up to 800 mm (31.5 in) long against 530 mm (20.9 in)
- 310 mm (12.2 in) of X and 825 mm (32.5 in) of Z travel against 185 mm (7.3 in) and 495 mm (19.5 in)
- 130 mm (5.1 in) of Y travel against 100 mm (3.9 in)
Verdict
Choose by part size and batch size. The DMG Mori CTX 350 4A is for series production of small bar-fed parts from stock up to 65 mm (2.6 in), where two turrets cutting at once and spindles running to 5,500 rpm and 6,000 rpm shorten the cycle. The DMG Mori CTX 450 is for larger chuck parts, shafts up to 800 mm (31.5 in) long and bar up to 102 mm (4 in), with more Y travel for milled features.
