Key Aspects:
• Computer Numerical Control (CNC): This means the machine's operations (laser power, speed, and beam movement)
are precisely controlled by a computer program. This allows for highly accurate, repeatable, and automated marking of
complex designs, serial numbers, QR codes, and logos from digital files.
• Fiber Laser: The laser source is a solid-state laser where light is generated and amplified within an optical fiber doped
with rare-earth elements like ytterbium. This technology produces a high-intensity, high-quality infrared beam (around
1064 nm wavelength) that is very efficient, has a long lifespan (over 100,000 hours), and requires minimal maintenance.
• Marking Machine: The machine works by directing the focused laser beam onto the material's surface, which absorbs
the energy. This interaction causes a change in the material's surface properties or appearance—such as localized
heating, melting, vaporization, or a color change—to create a permanent, high-contrast mark without physical contact.
Materials Processed:
• stainless steel, aluminum, gold, silver, brass
• hard plastics
* not suitable for materials like wood or glass, where CO2 lasers are typically used
Applications:
• Automotive (part identification, VIN codes)
• Electronics (circuit boards, microchips)
• Medical Device Manufacturing (surgical tools, implants)
Primary Benefits:
• Precision and Speed: They offer exceptional precision, capable of marking intricate details and small characters with
line widths down to micrometers. The galvanometer-based scanning systems used allow for very high marking speeds, ideal for
high-volume industrial production lines.
• Durability: The marks created are permanent and resistant to abrasion, heat, and chemicals, which is vital for product
traceability and anti-counterfeiting measures
