BODOR 12kW: 25 m/min Burr-Free Aluminum Cutting with Mixed Gas
Verified parameters from a fabricator specializing in aluminum components — where mixed gas delivered both speed and edge quality that pure nitrogen couldn't match.
The Challenge
A fabricator producing aluminum enclosures, brackets, and panels runs a BODOR 12kW fiber laser. Aluminum is notoriously difficult to cut clean — it's reflective, thermally conductive, and prone to burr formation. Their existing pure nitrogen setup produced acceptable edges but at speeds that limited daily output.
- Laser: BODOR 12kW fiber laser
- Material: Aluminum sheet (1.5mm–8mm)
- Products: Electronic enclosures, mounting brackets, decorative panels
- Previous gas: Pure nitrogen — clean edges but slow, high gas consumption
- Quality requirement: Cosmetic surfaces — no burrs, no scratches, no secondary finishing
The Solution: Mixed Gas Optimized for Aluminum
LISHI Series configured a mixed gas station with an aluminum-optimized N₂/O₂ ratio. For aluminum, the微量氧 component helps stabilize the cutting front against aluminum's high thermal conductivity, while the nitrogen主导 blend prevents oxidation that would ruin cosmetic surfaces.
The result: faster cuts than pure nitrogen, cleaner edges with zero burrs, and 35% lower gas cost — because mixed gas uses far less total gas volume than pure N₂ for the same cut length.
Verified Cutting Parameters
On-site test data from the BODOR 12kW end user. All cuts verified burr-free with cosmetic-grade surface finish.
| Thickness | Mixed Gas Speed | Previous N₂ Speed | Speed Gain | Surface Quality |
|---|---|---|---|---|
| 1.5mm | ~40 m/min | ~28 m/min | 1.4x | Mirror-clean, no burrs |
| 3mm | 25 m/min | ~16 m/min | 1.6x | Cosmetic-grade finish |
| 5mm | 15 m/min | ~9 m/min | 1.7x | Burr-free, no dross |
| 6mm | ~11 m/min | ~6.5 m/min | 1.7x | Clean edge, weld-ready |
| 8mm | 8 m/min | ~4.5 m/min | 1.8x | No burrs, no oxidation |
Key Takeaways
Aluminum Without Compromise
Mixed gas solves the classic aluminum dilemma: pure O₂ is fast but oxidizes the surface; pure N₂ is clean but slow. The optimized blend delivers both — speed and cosmetic quality in one gas stream.
35% Lower Gas Cost
Mixed gas uses significantly less total volume than pure nitrogen for the same cut length. The fabricator saw a 35% reduction in monthly gas expenses while increasing throughput.
BODOR Plug-and-Play
Zero modifications to the BODOR 12kW. The mixing station connected to the existing gas inlet in under 30 minutes. Same laser, same operator, same nesting software — just faster, cleaner cuts.
