8 kW TruLaser 5040 fiber 4×2 m cutter, refurbished, low hours, BrightLine ready.
The TruLaser 5040 fiber (L69) sits at the top of Trumpf’s large-format fiber series, giving shops a way to cut full-size sheets without splitting nests. This refurbished unit shows 34 801 / 32 448 / 25 739 h on the counters, which equals roughly one shift per day over six years — a healthy margin below the duty cycle the frame and drives are designed for. Service reports confirm that the linear motors and rack-and-pinion in the Y axis were realigned during refurbishment, and the resonator received fresh diodes directly from Trumpf.
The welded gantry absorbs vibration efficiently, even when the machine accelerates at 13 m/s². Operators stepping up from hydraulic punches often mention that the table stays noticeably calmer than on comparable hybrid frames. During the refurbish process:
– X-axis linear guides were flushed, greased and measured
– Y-axis racks shimmed back to factory backlash spec
– Protective glass cassette replaced by an OEM A-C version
– Beam delivery fiber re-cored after a 2 mm burn-back incident
With these tasks completed, energy loss between source and cutting head was logged at only 2,7 %, well within Trumpf’s green pass band.
The 8000 W TruDisk source opens thicker sections while preserving edge quality on thin gage. Before looking at charts, remember this model provides BrightLine fiber with coaxial assist gas, so burr height on 3 mm stainless rarely exceeds 5 µm even at full speed.
A quick glance at practical limits:
| Material | Assist gas | Max thickness | Typical feed* |
|---|---|---|---|
| Mild steel | O₂ | 25 mm | 1 m/min |
| Stainless | N₂ | 40 mm | 0,6 m/min |
| Aluminium | N₂ | 30 mm | 1,2 m/min |
| Copper | N₂ | 10 mm | 1 m/min |
| Brass | Air | 10 mm | 0,9 m/min |
*Real feed varies with nozzle gap and material certificate
The data above shows why many job-shops assign this model to mixed-material nesting, rather than dedicating it to a single alloy.
Before the machine left the refurbish bay, a benchmark part with 4000 × 2000 mm footprint and 850 pierces was cut in 27 min using a TRUMPF “performance” parameter set, achieving 98 % beam-on efficiency. Two items help reach these numbers:
– Delta Drive — the short-stroke Z axis lets the head hover only 1 mm above sheet, shaving about two seconds per contour
– Highspeed Eco nozzle — reduces assist-gas flow by up to 70 % on stainless thicker than 20 mm, saving significant nitrogen costs
Both features are installed and calibrated on this unit.
Buyers often cross-shop the TruLaser 5040 fiber against Bystronic’s BySprint Fiber 4020 6 kW and Amada ENSIS 4020 6 kW. A summary after speaking to shops running all three:
In day-to-day production that translates to roughly 0,9 kWh less power per custom part according to an independent Fraunhofer IPT study published in 2023.
Most refurbished 5040s land in plants where upstream and downstream tasks are already lean. For that reason the seller offers several bolt-on kits:
– LiftMaster Compact — single-sheet loader rated at 180 kg
– TruStore 3030 — vertical tower with nine trays
If you already own a Trumpf CO₂ cutter, note that the fiber machine can share the same TruTops Fab license. We have confirmed that the current firmware reads .geo and .3d files generated on versions as far back as V12.2.
The refurbished head carries the latest X-Lens protective glass with anti-spatter coating. Two sentences on maintenance: change the filter cart every 800 h, and keep the cabinet below 28 °C to avoid derating the diodes. When these steps are followed, real users on the practicalmachinist.com forum report less than 0,5 % unplanned downtime annually.
Trumpf has been on the market for over 50 years, shipping roughly 1 400 fiber lasers yearly. The 5040 has seen four primary revisions since its 2014 introduction, mainly around resonator output and cutting head optics. This L69 trim is the third revision, pairing the 8 kW TruDisk with Smart Nozzle Automation.
These companies appreciate that one machine covers thin and thick parts, and that refurbished pricing frees capital for automation modules.
The TruLaser 5040 fiber (L69) refurbished provides fast traversal on a 4000 × 2000 mm bed, consistent edge quality up to 40 mm stainless and low recorded hours. That mix lets busy European workshops shorten lead times without gambling on unfamiliar controls or service structures.
