How Does a Fiber Laser Cutting Machine Handle Different Materials?

Mag 14, 2025

Macchine per il taglio laser in fibra are widely used in industrial manufacturing due to their high precision, high speed, and adaptability to various materials. Different materials respond differently to laser cutting, so parameters must be adjusted accordingly for optimal results. Below is an overview of how fiber laser cutting machines process different materials and key considerations.

1. Metal Materials

(1) Acciaio al carbonio

Highly compatible, one of the most commonly cut materials with fiber lasers.

Assist Gas: Oxygen, promotes oxidation reaction to increase cutting speed.

Note: When cutting thick plates, control the focus and gas pressure to avoid dross.

(2)Acciaio inox

Does not oxidize easily, typically uses nitrogen to prevent discoloration.

Clean cutting edges, ideal for applications requiring high surface quality.

(3)Aluminum and Aluminum Alloys

Highly reflective, low laser absorption.

Requires high-power lasers, usually uses nitrogen or air as assist gas.

Note: Prone to back reflection—risk of damaging the laser source. Use appropriate reflection protection.

(4)Copper and Copper Alloys

Very high reflectivity and thermal conductivity, making them difficult to cut.

Requires high-power lasers with excellent beam quality.

Usually uses nitrogen or air as assist gas.

2. Non-Metal Materials (Not Recommended for Fiber Lasers; Use CO₂ Lasers Instead)

Fiber lasers are primarily designed for cutting metals. For non-metallic materials (e.g., wood, acrylic, PVC, glass), cutting performance is poor and may even damage the equipment. Common handling suggestions include:

(1)Plastics/Acrylic

Prone to melting and edge burning.

CO₂ laser cutting machines are recommended.

(2)Vetro

Fragile, difficult to control crack propagation during cutting.

Requires special laser technology, not suitable for fiber lasers.

3. Key Factors for Parameter Adjustment

Potenza laser: The thicker or more reflective the material, the higher the required power.

Velocità di taglio: Too fast may not penetrate; too slow may cause burn marks.

Assist Gas Type and Pressure: Affects both quality and speed of cutting.

Focus Position: Determines accuracy and penetration.

Pulse Frequency (if applicable): Affects edge smoothness.
