Roturn 400 GT

The machines of the ROTURN GT series with linear tool changers are particularly suitable for series machining of smaller workpieces. The shortest tool changing times and reliable functionality guarantee increased productivity. The inclined bed design ensures good chip flow. The hydraulic 3-jaw chuck with through-hole enables fast loading and short non-productive times, and the Siemens 828 D Basic control meets all requirements for current control technology. A flat top conveyor and a high-performance coolant system round out the standard equipment.
