FAQs

1. What materials can the Fiber Laser Marking Machine mark?

Fiber Laser Marking Machine can mark a wide range of materials, primarily metals such as stainless steel, aluminum, copper, brass, and titanium. It can also handle some non-metal materials like certain plastics, painted or coated surfaces, and anodized aluminum. The marking quality may vary based on material properties.

2. What is the difference between the F160 and F254 focus lenses?

The F160 lens provides a 100 mm × 100 mm marking area and delivers finer detail with deeper engraving due to its shorter focal length and smaller spot size. The F254 lens offers a larger 160 mm × 160 mm marking area, which is better for wider coverage but results in slightly lower resolution and marking depth because of the larger focal distance.

3. Does the machine require a cooling system?

Fiber Laser Marking Machine uses an air-cooling system, which means it does not require external water chillers. This makes the system compact, easy to maintain, and suitable for environments where minimal infrastructure is available.

4. What kind of maintenance does the machine require?

This Machine requires minimal maintenance. Regular cleaning of the lens, checking for dust on vents, and ensuring all components are securely connected are generally sufficient. Unlike older laser types, fiber lasers do not require consumables like gas or lamp replacements.

5. What is the function of the backward reflecting isolator in a Fiber Laser Marking Machine?

The backward reflecting isolator is a crucial component that protects the laser oscillator from damage. It works by using the particularity of the laser's wavelength and direction, along with a specially designed internal structure, to block laser beams that reflect back from the workpiece. This prevents the reflected laser from re-entering the oscillator and ensures long-term stability and safety of the laser system.
