DMG Mori CTX beta 1250 TC 4A vs DMG Mori CTX beta 450 TC
DMG Mori vs DMG Mori · Mill-Turn Machines
Summary
The DMG Mori CTX beta 1250 TC 4A and the DMG Mori CTX beta 450 TC are both turn-mill machines with a compactMASTER milling spindle and a 102 mm (4 in) bar capacity. The CTX beta 1250 TC 4A adds a second tool carrier, a turret with 12 or 16 driven stations, so two tools can cut at once. The CTX beta 450 TC works from a magazine of 60 pockets as standard, up to 200 pockets.
The CTX beta 450 TC has more cross travel, 750 mm (29.5 in) in X against 490 mm (19.3 in) and 250 mm (9.8 in) in Y against 200 mm (7.9 in), and a faster standard milling spindle, 15,000 rpm against 12,000 rpm. The CTX beta 1250 TC 4A takes slightly longer workpieces, up to 1,185 mm (46.7 in) against 1,100 mm (43.3 in).

Advantages
DMG Mori CTX beta 1250 TC 4A
- Second tool carrier with 12 or 16 driven stations, so the turret and the milling spindle cut at the same time
- 1,200 mm (47.2 in) of Z travel against 1,100 mm (43.3 in)
- Workpieces up to 1,185 mm (46.7 in) long against 1,100 mm (43.3 in)
DMG Mori CTX beta 450 TC
- 750 mm (29.5 in) of X travel against 490 mm (19.3 in)
- 250 mm (9.8 in) of Y travel against 200 mm (7.9 in)
- compactMASTER spindle at 15,000 rpm as standard against 12,000 rpm
- Magazine of 60 pockets as standard, up to 200 pockets, for long tool lists
Verdict
Choose by batch size and part complexity. The DMG Mori CTX beta 1250 TC 4A is for series production of shafts and bar-fed parts, where its second tool carrier lets two tools cut at once and shortens the cycle. The DMG Mori CTX beta 450 TC is for complex parts that need more milling reach, 750 mm (29.5 in) of X and 250 mm (9.8 in) of Y, a 15,000 rpm standard milling spindle and long tool lists of up to 200 pockets.
