Stainless steel engraving demands precision, durabilité, et efficacité. While CO2 lasers have long been a go-to for many workshops, leComMarker OMNI 1 Graveur laser UV redefines what’s possible on metal surfaces—without the limitations of traditional CO2 systems. In this deep dive, we’ll explore the technical advantages of UV laser technology, share actionable setup tips, and reveal how to achieve flawless results on stainless steel.
The Science Behind UV Lasers vs. CO2: Why OMNI 1 Wins
Lasers CO2 (10.6longueur d'onde µm) excel at engraving organic materials like wood or acrylic, but they struggle with metals. Here’s why the OMNI 1’sLaser UV (355longueur d'onde nm) dominates on stainless steel:
- Photon Energy Advantage
- UV photons pack 30x more energy per pulse than CO2 lasers, enabling direct interaction with metal surfaceswithout coating additives.
- Résultat: Crisp, oxidation-free marks that withstand abrasion and chemicals.
- Ultra-Fine Beam Focus
- The OMNI 1’s beam spot size can reach20µm (vs. CO2’s 250μm), allowing intricate details like 0.1mm fonts or micro QR codes.
- Pour la pointe: Pair this with ComMarker’sHigh-Precision Air Assist Kit to eliminate debris and maintain focus.
- Cold Marking Technology
- CO2 lasers melt the steel surface, causing thermal distortion and “halo” effects. L'OMNI 1 les usagesphotochemical ablation, vaporizing material at the molecular level.
- Proof: See the microscopic comparison below—OMNI 1 leaves smooth edges, while CO2 creates micro-cracks.
Optimizing OMNI 1 Settings for Stainless Steel
Maximize your machine’s potential with these tested parameters:
Basic Engraving (Black Annealed Mark)
| Paramètre | Valeur |
|---|---|
| Puissance laser | 80% (30W model) |
| Vitesse | 800mm/s |
| Fréquence | 50kHz |
| Laissez-passer | 1 |
| Focus Height | 2millimètre (utiliser ComMarker Auto-Focus Gauge) |
Note: For darker marks, increase frequency to 80kHz and reduce speed to 500mm/s.
Gravure profonde (0.2-0.5mm Depth)
| Paramètre | Valeur |
|---|---|
| Puissance laser | 100% |
| Vitesse | 300mm/s |
| Fréquence | 20kHz |
| Laissez-passer | 3-5 |
| Air Assist Pressure | 25 PSI (prevents slag buildup) |
⚠️ Critical: Always use the OMNI 1 Dedicated Exhaust System to remove toxic chromium particles.
Dépannage des problèmes courants
Problem 1: Faded or Inconsistent Marks
- Checklist:
- Clean the lens with ComMarker UV Lens Wipes. Dust reduces beam intensity.
- Verify focus height—misalignment is the #1 cause of blurry marks.
- Replace the air assist filter if airflow weakens.
Problem 2: Burn Marks or Discoloration
- Solution:
- Lower laser power to 70% and increase speed to 1000mm/s.
- Apply a thin layer of Laser Anti-Spatter Spray to protect the surface.
Étude de cas du monde réel: Aerospace Part Marking
Challenge: A manufacturer needed to engrave 0.2mm-tall serial numbers on 316L stainless steel bolts. CO2 lasers failed to meet ISO/ASTM durability standards.
OMNI 1 Solution:
- Utilisé 20W OMNI 1 avec Rotary Fixture Pro.
- Paramètres: 65% pouvoir, 1200mm/s, 60kHz.
- Résultat: Passed 500-hour salt spray tests with zero corrosion—saving $12k/year vs. outsourcing.
Why Choose OMNI 1 Over CO2?
| Factor | OMNI 1 Laser UV | Laser CO2 |
|---|---|---|
| Mark Quality | No heat distortion | Thermal halo common |
| Vitesse | 2x faster on metals | Slower, multi-pass needed |
| Operating Cost | $0.10/heure (no gas) | $0.30/heure (gas assist) |
| Material Prep | None required | Coatings mandatory |
