Capabilities of Fiber Lasers Cutting by Material Thickness

Fiber laser cutting machines offer versatile applications across different materials, allowing precise cuts from thin sheets to thicker metal plates. This capability is due to the advanced technology in fiber lasers, which uses a highly concentrated laser beam to cut through materials efficiently.

Metals

Fiber laser cutters are widely used for cutting metals like steel, aluminum, and copper. The cutting process involves directing a high-power laser beam at the material, melting or vaporizing it along a path. This results in clean and accurate cuts with minimal waste. Here are the specific parameters for various metals:

Steel

• Minimum Thickness: Approximately 0.5 mm
• Maximum Thickness: Up to 25 mm
• Notes: Steel, including alloy steel and carbon steel, is a common application for fiber lasers. The high power levels of fiber laser cutting machines ensure efficient cutting with excellent surface cutting quality. Proper settings like laser cutting speed and auxiliary gas type can enhance the cutting ability and reduce burrs.

Aluminum

• Minimum Thickness: As low as 0.5 mm
• Maximum Thickness: Up to 30 mm with very high-power lasers
• Notes: Aluminum is another material where fiber lasers excel. The aluminum plate’s reflective properties require careful adjustment of the laser beam focus and power. Using a fiber laser cutting machine, you can achieve smooth edges on aluminum alloy sheets.

Stainless Steel

• Minimum Thickness: About 0.5 mm
• Maximum Thickness: Up to 20 mm
• Notes: Stainless steel is popular in industries for its durability and resistance to corrosion. Fiber lasers provide a high-quality cutting process for stainless steel, ensuring precision parts with minimal post-processing required.

Copper and Brass

• Minimum Thickness: Around 0.5 mm
• Maximum Thickness: Up to 10 mm
• Notes: Cutting copper and brass can be challenging due to their reflective nature. Fiber laser cutters equipped with specific settings can handle these materials efficiently, producing quality cutting results without compromising on speed.

Non-Metals: Plastics and Composites

Fiber lasers are not limited to metals; they also cut non-metallic materials such as plastics and composites. The ability to adjust laser power and speed makes fiber lasers suitable for these materials.

Plastics

• Minimum Thickness: Typically around 1 mm
• Maximum Thickness: Up to 10 mm
• Notes: When cutting plastics, fiber lasers provide clean edges without melting or warping. The precise control over the laser beam allows for detailed cuts in various plastic types.

Composites

• Minimum Thickness: Around 1 mm
• Maximum Thickness: Up to 20 mm for some composite materials
• Notes: Composite materials can vary widely in composition and thickness. Fiber lasers offer a flexible solution, adapting to the unique characteristics of each material for optimal cutting quality.
