DMG Mori CTX Gamma 3000 TC 4A

The DMG Mori CTX Gamma 3000 TC 4A is the premium large-format turn-mill center combining the CTX gamma 3000 TC platform's 3,050 mm turning length and 630 mm swing with a factory-integrated 4-axis opposed twin-turret configuration and 5-axis milling head — a machine designed for shops that machine the most complex long, large-diameter shaft and cylindrical parts in aerospace, energy, defense, and heavy industry. The 4A designation refers to the four-axis opposed turret configuration that enables simultaneous upper and lower turret cutting for dramatically reduced cycle times on complex parts.

At its core, the CTX Gamma 3000 TC 4A builds on the standard CTX gamma 3000 TC architecture: a mineral-cast GILDEMEISTER Casting bed, main spindle of 52 kW (70 hp) at 3,500 RPM with 1,550 Nm of torque through a 15-inch chuck, and bar capacity of 127 mm (5.0 in). The compactMASTER turn-mill spindle adds 36 kW (48 hp) and 220 Nm through HSK-A63 at up to 12,000 RPM, with optional 20,000 RPM for high-speed finishing. B-axis swivel spans 240 degrees via direct-drive motor for simultaneous 5-axis milling operations anywhere along the full 3,050 mm turning length.

The 4A addition integrates a lower VDI turret (12 stations, VDI 60 or optional VDI 40) positioned diametrically opposite the upper compactMASTER milling head. This enables simultaneous cutting on both the upper and lower quadrants of large workpieces — a critical productivity multiplier for complex shafts where multiple diameters, grooves, threads, and features must be machined in sequence. The upper milling head handles 5-axis contouring and milled features while the lower turret simultaneously turns, grooves, or threads on another feature, cutting the effective cycle time for complex parts by 30-50% compared to single-turret configurations.

Y-axis travel of 420 mm (16.5 in) — plus/minus 210 mm from centerline — provides wide off-center reach for milled features on large-diameter work. Z-axis travel of 3,100 mm (122 in) covers the full 3,050 mm turning length. Maximum turning diameter is 700 mm (27.6 in). Axis travels deliver the full range of turning and milling positions needed for complex done-in-one large shaft machining.

Tool magazine starts at 36 stations and expands to 80, 120, or 180 via chain magazine. Optional sub-spindle provides backworking capability for shorter parts. The machine weighs approximately 35,000 kg (77,162 lb) in 4A configuration, slightly heavier than the single-turret 3000 TC due to the lower turret infrastructure. Control is CELOS with Siemens 840D solutionline.

For aerospace manufacturers producing landing gear components, turbine shafts, and complex structural cylinders, for energy producers machining long pump shafts, compressor shafts, and power generation rotors, the CTX Gamma 3000 TC 4A represents the most complete done-in-one solution at the top of the large-format turn-mill category.
