DMG Mori vs DMG Mori · Mill-Turn Machines
Summary
The DMG Mori CTX beta 450 TC and the DMG Mori CTX gamma 1250 TC are both turn-mill machines with a compactMASTER milling spindle. The CTX gamma 1250 TC is the larger machine: 420 mm (16.5 in) of Y travel against 250 mm (9.8 in), a 127 mm (5 in) bar capacity against 102 mm (4 in), and workpieces up to 1,250 mm (49.2 in) long against 1,100 mm (43.3 in).
Its standard ISM 102 spindle is rated 60.3 hp and 567.9 ft lb, against a maximum 36 kW and 720 Nm on the CTX beta 450 TC. The CTX beta 450 TC has the faster standard milling spindle, 15,000 rpm against 12,000 rpm. Its tool storage is 60 pockets as standard and up to 200; the CTX gamma 1250 TC lists a 36-fold disc magazine and at most 180 stations in the optional chain magazine.

Advantages
DMG Mori CTX beta 450 TC
- compactMASTER milling spindle at 15,000 rpm as standard against 12,000 rpm
- Equally rated left and right spindles for six-sided machining
- 60 pockets as standard and up to 200 pockets for long tool lists
DMG Mori CTX gamma 1250 TC
- 420 mm (16.5 in) of Y travel against 250 mm (9.8 in)
- 127 mm (5 in) bar capacity against 102 mm (4 in)
- 60.3 hp standard spindle against a maximum 36 kW
- 1,300 mm (51.2 in) of Z travel and workpieces up to 1,250 mm (49.2 in) against 1,100 mm (43.3 in)
Verdict
Choose by part diameter and how far off-center the milling goes. The DMG Mori CTX gamma 1250 TC is for flanges, housings and discs that need 420 mm (16.5 in) of Y travel, bar up to 127 mm (5 in) and the 60.3 hp standard spindle. The DMG Mori CTX beta 450 TC is for smaller complex parts machined on six sides, where its 15,000 rpm standard milling spindle and equally rated left and right spindles matter more than size.
