DMG Mori CTX 450 vs DMG Mori CTX 450 4A
DMG Mori vs DMG Mori · CNC Lathes
Summary
The DMG Mori CTX 450 and the DMG Mori CTX 450 4A share most of their published figures: 102 mm (4 in) bar capacity, 130 mm (5.1 in) of Y travel, workpieces up to 800 mm (31.5 in) long and a 5,500 rpm second spindle (ISM 65). The CTX 450 4A is the version built to cut with two turrets at once.
The CTX 450 has slightly more travel, 310 mm (12.2 in) in X against 280 mm (11 in) and 825 mm (32.5 in) in Z against 760 mm (29.9 in). The CTX 450 4A has the faster main spindle: its left spindle (ISM 80) reaches 4,500 rpm against 4,000 rpm on the CTX 450. An ISM 102 left spindle at 3,500 rpm and an ISM 80 right spindle at 4,500 rpm are extra-cost options on the CTX 450 4A.

Advantages
DMG Mori CTX 450
- 310 mm (12.2 in) of X travel against 280 mm (11 in)
- 825 mm (32.5 in) of Z travel against 760 mm (29.9 in)
- Suited to chuck parts and shafts, including automated shaft production
DMG Mori CTX 450 4A
- 4,500 rpm left spindle (ISM 80) against 4,000 rpm
- Two turrets cutting at once to shorten cycle times
- Larger spindles offered as options on both sides: ISM 102 left, ISM 80 right
Verdict
Same size class, different production style. Choose the DMG Mori CTX 450 for chuck parts, shafts and mixed turn-mill work, where its extra X and Z travel, 310 mm (12.2 in) and 825 mm (32.5 in), give more room. Choose the DMG Mori CTX 450 4A for bar parts finished on both sides in series, where two turrets cutting at once and a 4,500 rpm left spindle bring the cycle time down.
