Laser Engraving Graphite

The parts were engraved with a 20 watt q-switched ytterbium fiber laser and 160 mm focal length lens. The 160mm focal length lens has a working distance of 176mm from lens to part. The marks were done at 3 different depths using 2 passes, 4 passes and 6 passes. The artwork on the part was duplicated.

Laser Engraving Titanium

Laser Engraving Application:

The parts were marked using a 20 watt q-switched ytterbium fiber laser with 160 mm focal length lens. The titanium coated steel was engraved to create a dark mark on the surface of the samples. The parts were marked using approximately 17 watts of power, with a frequency of 25kHz, at a speed of 5 inches per second, resulting in a cycle time of 3.54 seconds.

Laser Engraving Steel

Laser Engraving Application:

Laser engraving was accomplished using a 20-Watt Fiber Laser using a 160 mm lens. The steel was engraved using 18 Watts of power, frequency of 25 kHz, speed of 10" per second, resulting in a cycle time of 2.75 seconds per row of numbers.

Technology: Q-Switched Fiber Laser

Wattage: 20 Watt

Wavelength: 1060nm - 1070nm

Focal Length Lens: 160mm

Laser Engraving Brick

Laser Engraving Application:

Deep engraving was done on this red brick sample to show the capabilities of using CO2 lasers for engraving purposes. The depth and speed at which the process can be done simply depends on the power of the CO2 laser system.

Deep Laser Engraving of Aluminum

Laser Engraving Application:

Deep laser engraving of aluminum using a paint removal process. The powder coated red aluminum part was laser marked using the i-Series Fiber Laser Kit with a 254mm lens. The part was engraved with a frequency of 50 kHz. The fastest method to remove the paint was to mark each letter in the logo individually. Removing the paint going letter by letter gave the paint less time to cool of resulting in a much faster cycle time. The red part with 0.0045" coating needed 140 seconds to be removed.
