Mitsubishi Electric ML3015eX-F

The Mitsubishi Electric ML3015eX-F is a flying-optics fiber laser cutting machine for 3,050x1,525 mm sheet, built in three versions by oscillator rated output: the ML3015eX-F40 at 4 kW, the ML3015eX-F60 at 6 kW and the ML3015eX-F80 at 8 kW. The sheet stays still on its pallet while the beam moves on three axes, with travels of 3,100 mm in X, 1,565 mm in Y and 150 mm in Z.

The three versions share those travels and differ mainly in the services they need. Power input, including oscillator and chiller, is 43 kVA on the 4 kW version, 50 kVA on the 6 kW version and 56 kVA on the 8 kW version. Doubling the laser output therefore raises electrical demand by only about 30%. The processing machine body moves even less: approx. 9,000 kg, approx. 9,100 kg and approx. 9,300 kg in the same order. The reference footprint is 12,790×5,150 mm for the two smaller versions and 12,990×5,150 mm for the ML3015eX-F80, around four times the sheet length in either case.

Weights have to be added up for the foundation. Beyond the processing machine body there is a pallet changer of approx. 2,100 kg and the LCU8AIF chiller, an air-cooled inverter type, at approx. 800 kg. Each pallet carries up to 950 kg at a work support height of 880 mm.

Rapid traverse is max. 140 m/min for the X and Y axes combined. Positioning accuracy is 0.05/500 mm in X and Y and 0.1/100 mm in Z, with ±0.01 mm repeatability in X and Y. Control is simultaneous on X, Y and Z, with Z-axis profiling control on top, the function that holds the head at a set height over a sheet that is not perfectly flat. The GX-F shares the 3,100 mm and 1,565 mm X and Y travels but has 120 mm of Z and a 170 m/min simultaneous rapid traverse.
