Machine Comparison
DMG Mori CTX 450 4A vs DMG Mori CTX 550
DMG Mori vs DMG Mori · CNC Lathes
Summary
The DMG Mori CTX 450 4A and the DMG Mori CTX 550 are both turning centers with a 102 mm (4 in) bar capacity, 130 mm (5.1 in) of Y travel and a 5,500 rpm second spindle (ISM 65). They differ in length and in layout: the CTX 450 4A is a two-turret production machine, the CTX 550 a longer machine for shafts.
The CTX 550 takes workpieces up to 1,225 mm (48.2 in) long against 800 mm (31.5 in), and has 310 mm (12.2 in) of X travel against 280 mm (11 in). The CTX 450 4A has the faster main spindle, 4,500 rpm with the ISM 80 against 3,250 rpm; its ISM 102 left spindle, an extra-cost option, runs to 3,500 rpm.

Advantages
DMG Mori CTX 450 4A
- 4,500 rpm left spindle (ISM 80) against 3,250 rpm on the CTX 550 main spindle
- Two turrets cutting at once to shorten cycle times
- Suited to bar parts finished on both sides in one cycle
DMG Mori CTX 550
- Workpieces up to 1,225 mm (48.2 in) long against 800 mm (31.5 in)
- 310 mm (12.2 in) of X travel against 280 mm (11 in)
- Suited to long shafts and heavy turning at low spindle speed
Verdict
Choose by part length and production style. The DMG Mori CTX 450 4A is for bar and chuck parts up to 800 mm (31.5 in) long made in series, where two turrets cutting at once and a 4,500 rpm left spindle shorten the cycle. The DMG Mori CTX 550 is for shafts up to 1,225 mm (48.2 in) long and heavy turning at lower speed on its 3,250 rpm main spindle. Bar capacity, Y travel and second-spindle speed do not separate them.
