Mitsubishi Electric GX-F

The Mitsubishi Electric GX-F is a fiber laser cutting machine for sheet up to 120.1 in (3,050 mm) × 60.0 in (1,525 mm), sold with a 4 kW or 6 kW ytterbium doped fiber source on the platform Mitsubishi Electric names ML 3015 GX-F. Axis travels are 122.0 in (3,100 mm) in X, 61.61 in (1,565 mm) in Y and 4.72 in (120 mm) in Z, so the head reaches a little past every edge of a full sheet.

Speed is where the table is most specific. Simultaneous rapid traverse is 6,700 in/min (170 m/min) and the maximum cutting feedrate is 3,937 in/min (100 m/min). On thin sheet with many short features a laser spends much of its time repositioning between cuts, and the rapid rate governs that part of the cycle. Whether a job ever reaches the cutting feed limit depends on material, thickness and power, none of which the table breaks down. No maximum thickness is published on the product page for either source, so capacity in a given material has to come from a cutting chart.

Positioning accuracy is 0.0019 in per 20 in (0.05 mm per 500 mm) and repeatability is ±0.00039 in (0.0099 mm). The source wavelength is 1.07 µm.

For installation, the table carries workpieces up to 2,094 lb (950 kg) at a pass height of 35 in (890 mm). The machine weighs 15,432 lb (7,000 kg) and its footprint is 415.0 in (10,541 mm) × 135.0 in (3,429 mm), roughly three and a half times the sheet length, so the layout drawing matters more than the sheet size when planning the bay. Next to the ML3015eX-F, the GX-F has the same 3,100 mm and 1,565 mm X and Y travels, 120 mm of Z against 150 mm, and a 170 m/min simultaneous rapid against a maximum of 140 m/min.
