A large turn/mill centre has been introduced by DMG for machining components up to 3m in length and 700mm in diameter. Built by Gildemeister Drehmaschinen GmbH, the CTX gamma 3000 TC is equipped with a powerful ±120° B-axis for flexible turning operations and milling in up to five axes simultaneously.

The machine has the option of a 12 station turret as a second tool holder which can have live VDI40 tools in all stations rated at 9.4kW/4,000rpm/30Nm. The additional turret opens up the possibility of multi-axis machining on one spindle or parallel machining on both main and counter spindles. Target applications are longer shaft parts used in power plants, turbines, marine engines and wind power.

The main spindle drive has up to 59kW of power, 2,500rpm and 4,000Nm torque while an optional 52kW counter spindle offers 4,000rpm and 2,200Nm torque. The HSK-64A or HSK-100 turning/milling spindle is also powerful at up to 32kW/145Nm and is served by a 36 tool disc turret or a 120 position chain magazine. High productivity is further promoted by 40/40/30m/minute rapids in X/Y/Z. Two steady rests may be used to support longer workpieces.

The structural design of the CTX gamma 3000 TC is based on a robust travelling column mounted horizontally on the Z-axis. Linear guideways are widely spaced for stiffness and stability during machining and high precision is ensured via linear scales, thermo-symmetrical design and active cooling of machine elements including main, counter and B-axis spindles.

Control is provided by the Siemens 840D solutionline with ERGOline panel and 19 inch screen. It includes ShopTurn 3G for the workshop-oriented programming of turn/mill processes as well as additional functions for efficient tool management.
