Trumpf TruLaser Tube 3000 Fiber

The Trumpf TruLaser Tube 3000 Fiber is a tube laser cutting machine for small and medium sections: round tube up to 152 mm (6 in) in diameter as standard, 170 mm as an option, at no more than 18.5 kg/m. It cuts with a 2 kW or 3 kW laser, the TruFiber 2001 or TruFiber 3001.

The weight limit decides what the machine accepts more often than the diameter does. A thin-wall tube of 152 mm is well inside 18.5 kg/m, while a heavy-wall section of the same diameter may not be, so work out kilograms per metre for your heaviest stock before anything else. The TruLaser Tube 5000 raises the limit to 25 kg/m at the same 152 mm standard diameter, which makes the choice between the two a matter of wall thickness and laser power, not tube size.

Mild steel is listed at 8 mm (0.31 in) with either laser. In stainless steel and aluminum the TruFiber 2001 reaches 4 mm (0.16 in). For the TruFiber 3001 the table gives a pair of values, 6 mm / 4 mm, without saying what separates the two, so ask Trumpf which one applies to your cut. Copper and brass are listed at 4 mm (0.16 in) with the 3 kW laser, and bevel cuts of up to 45 degrees are possible.

Bar length depends on the loader. With the LoadMaster 6.5 the raw material can be 6,500 mm long and the automatic loading weight is 120 kg; the LoadMaster 8.0 extends that to 8,000 mm, with 148 kg. Both weights are simply the per-metre limit carried over a full bar, so any bar the machine can cut can also be loaded automatically. Unloading units are listed for finished parts of 3000 mm, 4750 mm, 6500 mm and 8000 mm. Average power consumption is 6 kW with the 2 kW laser and 9 kW with the 3 kW laser.
