Our best estimate for a cnc lathes / turning center in this class — not a quote from DMG Mori. Configuration moves it a long way.
Overview
The DMG Mori CTX beta 1250 is a universal lathe for parts up to 1,185 mm (46.7 in) long, and the listed figures describe it with turn-mill equipment: a B-axis milling spindle, a tool magazine and a lower turret. It is not in DMG MORI's current lineup and is probably an older model. Treat the listed figures as a guide and confirm them on any machine you are offered.
The envelope is a 500 mm (19.7 in) swing with a machining diameter of 340 mm (13.4 in). Travels are 490 mm (19.3 in) in X, 1,200 mm (47.2 in) in Z and ±125 mm in Y, 250 mm (9.8 in) in total. That Y stroke is long for a lathe and goes with the milling spindle.
The main spindle is listed at 5,000 RPM, 33 kW (44.2 hp) and 580 Nm. A sub-spindle with 6,000 RPM and 25 kW (33.5 hp) is optional. The turn-mill spindle runs at 12,000 RPM, or 20,000 RPM as an optional high-speed version, with 22 kW (29.5 hp) and 120 Nm on an HSK-A63 interface, Capto C6 being the option. It swivels ±120° on a Direct Drive B-axis and draws from a magazine of 24 tools as standard, or 48 or 80. A lower turret with 12 or 16 driven stations (VDI40) is also listed, with a 10,000 RPM DirectDrive.
Rapids are 40 / 40 / 50 m/min in X, Y and Z, or 60 m/min in Z with the linear drive. Positioning accuracy is listed as under 6 µm with linear scales. The control is CELOS with Siemens 840D sl on a 21.5 in ERGOline panel. Weight is about 8,000 kg (17,637 lb) and floor space 10.2 m².
Among current models, the CTX 750 in its Type 1250 length has 1,300 mm (51.2 in) of Z travel with 435 mm (17.1 in) of X and 170 mm (6.7 in) of Y.

Strengths & Limitations
Strengths
- B-axis turn-mill spindle with 12,000 RPM, 22 kW (29.5 hp) and 120 Nm on an HSK-A63 interface
- ±125 mm of Y travel, 250 mm (9.8 in) in total
- Main spindle listed at 5,000 RPM with 33 kW (44.2 hp) and 580 Nm
- Tool magazine with 24 tools as standard, or 48 or 80
- Rapid traverse of 40 / 40 / 50 m/min in X, Y and Z
Limitations
- Machining diameter is 340 mm (13.4 in), well inside the 500 mm (19.7 in) swing
- The sub-spindle is optional, so a given machine may not have one
- The 20,000 RPM turn-mill spindle is an optional high-speed version; the base figure is 12,000 RPM
- The under 6 µm positioning accuracy is listed with linear scales, and 60 m/min in Z needs the linear drive
- The listed bar capacity and spindle bore do not agree, so measure the bore on the machine
