Unlocking Thick Metal: Why 1000W Fiber Lasers Dominate Sheet Cutting

In recent years, 1000W fiber laser cutting machines have demonstrated remarkable performance in sheet metal cutting, especially in cutting thick metal sheets, and have gradually become a mainstream choice in the market. Below are some reasons why 1000W fiber lasers dominate sheet cutting:

Excellent Cutting Performance

• Impressive Cutting Thickness: A 1000W fiber laser cutting machine can cut various metal materials, such as carbon steel up to 10mm, stainless steel up to 5mm, aluminum up to 3mm, and copper up to 3mm.
• Fast Cutting Speed: For carbon steel thinner than 2mm, a 1000W fiber laser cutting machine can achieve a cutting speed of up to 8 meters per minute. For 6mm carbon steel, the cutting speed is approximately 1.6 meters per minute, and for 10mm carbon steel, the speed ranges from 0.6 to 0.7 meters per minute. When cutting 1mm stainless steel with nitrogen as the assist gas, the cutting speed can reach 6.8-8.6 meters per minute. For 2mm stainless steel, the speed ranges from 3.0 to 5.5 meters per minute, and for 3mm stainless steel, it is 1.5-2.0 meters per minute.

High Cutting Quality

• Smooth and Clean Cutting Surface: The focused beam produced by fiber lasers enables precise cutting with minimal roughness or irregularities. For thin sections, the cutting width is uniform, and accuracy can reach ±0.01mm. The concentrated beam energy and assist gas can cleanly cut through tough materials like stainless steel, with burr heights typically less than 0.1mm. The narrow focused beam minimizes heat input, resulting in a smaller heat-affected zone (HAZ), usually less than 0.3mm. This reduces material softening, warping, and residual stresses, ensuring high cutting quality.
• Minimal Burr and Deformation: 1000W fiber laser cutting machines produce good spot quality with minimal deformation. The cutting surface is smooth and aesthetically pleasing, with minimal burrs and deformation, reducing the need for post-processing and saving on production costs and time.

High Precision

Fiber lasers generate beams with high mode quality and brightness. The 1000W fiber laser cutting machine adopts advanced optical systems and servo motor drive systems, enabling precise control of laser beam focus and cutting head movement. This ensures cutting accuracy within ±0.05mm and effectively guarantees dimensional accuracy for complex-shaped parts. Even for intricate designs with sharp corners and edges, the machine can achieve exceptional dimensional precision and surface finish.

Low Operating Costs

• Energy Efficiency: As solid-state lasers, fiber lasers convert electrical energy into optical energy with high efficiency, offering a光电conversion efficiency of over 30%. This is significantly higher than CO2 lasers and other types of lasers, reducing electricity consumption and lowering operating costs.
• Low Maintenance Costs: Unlike traditional laser cutting machines that require frequent replacement of electrodes and nozzles, fiber laser cutting machines have no consumables like electrodes. The optical path does not need adjustment, core components require zero maintenance, and the overall maintenance cost is relatively low.
• Material Saving: The nesting software of 1000W fiber laser cutting machines can automatically optimize the layout of cutting patterns, maximizing material utilization and reducing waste. This helps businesses save on material costs.

Strong Adaptability

A 1000W fiber laser cutting machine can cut a wide range of metal materials, including stainless steel, carbon steel, galvanized sheet, aluminum, copper, brass, titanium, aluminum alloys, titanium alloys, pickling plate, and more. It is suitable for sheet metal processing in industries such as automotive manufacturing, machinery processing, kitchenware production, advertising, hardware, and electrical enclosures. Its versatility meets diverse cutting needs.

High Automation and Intelligence

Equipped with advanced CNC systems and automatic focusing laser cutting heads, the 1000W fiber laser cutting machine enables automatic adjustment of the focal length. It can adapt to different thicknesses of metal sheets for cutting without manual intervention. Additionally, features like automatic lubrication and anti-collision functions enhance cutting efficiency and precision while reducing equipment damage rates and maintenance costs. The machine can operate stably over long periods, improving production efficiency and reliability.

Good Cost-Performance Ratio

Compared to higher-power fiber laser cutting machines, 1000W fiber laser cutting machines have a lower initial investment cost. They can meet the cutting needs of most thick metal sheets while offering relatively low operating and maintenance costs. This provides businesses with a higher return on investment and is more acceptable to the market.

The rise of 1000W fiber laser cutting machines also reflects advancements in fiber laser technology. Continuous improvements in laser beam quality, output power stability, and optical system design have enhanced their cutting performance and reliability. Meanwhile, the development of automation and intelligent control systems has further improved cutting efficiency and quality, expanding application fields. As technology evolves and market demand grows, 1000W fiber laser cutting machines are expected to deliver even better performance in sheet cutting.
