Fiber Laser Marking Machine in Metal Processing Industry
Fiber laser marking machines are widely used in the metal processing industry for high-precision, permanent marking on various metals. These machines utilize a fiber laser source to create clean, durable, and high-contrast marks without physical contact, making them ideal for industrial applications.
How Fiber Laser Marking Works on Metals
Laser Beam Generation
A fiber laser source generates a concentrated beam (typically 1064 nm wavelength).
The beam is directed through a galvanometer scanner for precise control.
Surface Interaction
Annealing marks (color changes without material removal, common for stainless steel).
Engraving (material ablation for deep marks).
Etching (shallow surface removal).
The laser beam hits the metal surface, causing localized heating.
Depending on settings, it can create:
Permanent Mark Formation
The process alters the metal's surface properties, producing high-contrast, wear-resistant marks.
Key Applications in Metal Processing
✔ Part Identification – Serial numbers, barcodes, QR codes.
✔ Branding & Logos – Company logos, product branding.
✔ Industrial Traceability – Date codes, batch numbers for tracking.
✔ Aerospace & Automotive – VIN numbers, component labeling.
✔ Medical Devices – Surgical tool markings for compliance.
✔ Jewelry & Precision Tools – Fine engraving for customization.
Advantages of Fiber Laser Marking in Metal Processing
✅ High Speed & Efficiency – Faster than traditional engraving methods.
✅ Precision & Clarity – Micron-level accuracy for fine details.
✅ Non-Contact Process – No tool wear, minimal material damage.
✅ Durable Marks – Resistant to heat, chemicals, and abrasion.
✅ Low Maintenance – Fiber lasers have a long lifespan (100,000+ hours).
✅ Automation-Friendly – Integrates with CNC and robotic systems.
Metals Suitable for Fiber Laser Marking
Stainless Steel (Best for annealing marks)
