Heavy Duty Turn-Mill Centre For Components Up To Three Metres Long
A large turn-mill centre has been introduced by DMG for machining components up to three metres in length and 700 mm in diameter. Built by Gildemeister Drehmaschinen GmbH, the CTX gamma 3000 TC is equipped with a powerful ± 120 degree 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 9.4 kW / 4000 rpm / 30 Nm. The additional turret opens up the possibility of multi-axis machining at one spindle or parallel machining at 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 59 kW of power, 2,500 rpm and 4,000 Nm torque while an optional 52 kW counter spindle offers 4,000 rpm and 2,200 Nm torque. The HSK-64A or HSK-100 turning / milling spindle is also powerful at up to 32 kW / 145 Nm and is served by a 36-tool disc turret or a 120-position chain magazine. High productivity is further promoted by 40 / 40 / 30 m/min 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. High precision is ensured by 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 3 G for workshop-oriented programming of turn / mill processes as well as additional functions for efficient tool management.
