Amada LCG-3015AJ

The Amada LCG-3015AJ is Amada's flagship fiber laser cutting system, built around their proprietary AJ (Amada Journal) fiber engine. It's a flying-optics machine with a 3,070 x 1,550 mm (121 x 61 in) working area -- the standard 5x10 ft sheet size that covers the vast majority of North American and European fabrication work. The sheet stays stationary while the cutting head moves across all three axes, which means you're not accelerating heavy material and you get better accuracy at speed.

Amada offers the LCG-3015AJ in five power configurations: 2 kW, 3 kW, 4 kW, 6 kW, and 9 kW. The 3 kW version -- the most common in the field -- cuts up to 18 mm (0.71 in) mild steel, 15 mm (0.59 in) stainless, 12 mm (0.47 in) aluminum, 8 mm (0.31 in) brass, and 6 mm (0.24 in) copper with oxygen or nitrogen assist gas. Higher-wattage models push those numbers further and dramatically increase cutting speed on thin stock. The 9 kW variant, introduced in 2017, handles 25 mm mild steel and tears through thin gauge material at speeds that make CO2 lasers look like they're standing still.

The drive system uses AC servo motors with a helical rack-and-pinion arrangement, delivering rapid traverse speeds of 120 m/min (4,724 ipm) on both X and Y axes and 80 m/min (3,150 ipm) on Z. Repeatability is +/- 0.005 mm (0.0002 in), which is tight enough for precision sheet metal work without secondary operations. The low center-of-gravity carriage design keeps vibration down at high acceleration rates, so you can actually use those rapid speeds without sacrificing cut quality.

Amada designed the AJ fiber engine in-house rather than sourcing from IPG or nLIGHT like most competitors. The single-module resonator (no beam combiner on the 3 kW) delivers a higher beam density that translates to faster piercing and cleaner cuts, especially on reflective metals like copper and brass that gave CO2 lasers fits. Energy consumption runs roughly one-third of an equivalent CO2 setup -- the fiber resonator converts electrical energy to laser light at about 30% efficiency vs 10% for CO2.

The machine runs on Amada's AMNC 3i control with a touchscreen LCD display. It handles X, Y, Z simultaneous interpolation plus focus lens position (B-axis) and laser power modulation. Programming happens through Amada's AP100 CAM software, which handles nesting, toolpath generation, and cutting condition databases. The control stores material-specific cutting parameters, so operators can switch between jobs without manually dialing in feed rates and power settings.

Table loading capacity is 920 kg (2,028 lb), and the machine itself weighs 9,100 kg (20,062 lb) with overall dimensions of 10,136 x 2,840 x 2,432 mm (399 x 112 x 96 in). Power requirements are 200V/60Hz three-phase (+/- 10%). Amada offers several automation options including the ASFH compact load/unload system and multi-shelf tower storage for lights-out production.

New LCG-3015AJ machines with a 3-4 kW laser list around $450,000-$600,000 depending on configuration and automation. Used machines from 2014-2018 trade in the $100,000-$250,000 range depending on laser hours, power level, and included automation. A 2015 model with 4 kW laser and ASFH tower has been listed around $199,500. Direct competitors include the Trumpf TruLaser 3030/3040, Bystronic ByStar Fiber, and Mazak Optiplex 3015 NEO. Amada's edge is the in-house fiber engine with its higher beam density and the integrated automation ecosystem.

Note: Amada has since introduced the ENSIS series as the successor to the LCG-AJ line, featuring variable beam control technology. The LCG-3015AJ remains widely available on the used market and is still supported by Amada's service network.
