At Thor Ahlgren, we see steel as a malleable material, like the old masters in the early days of industry. We have embraced the legacy of the early industrial years and combined it with modern technology. At the same time, we have preserved the spirit of hard work and craftsmanship that characterized those times. Through our laser process, we produce parts that meet customer requirements - from simple to complex geometries
Do you have an article that needs laser cut in Småland? We specialize in production customization to ensure that production is as efficient as possible and according to your specifications. With our machines, we laser cut parts with precision in shape and surface. In case of high tolerance requirements, we can further process the cut blank in our CNC machines. Whether it is a small or large series, we always deliver with the agreed precision.
Laser cutting is a versatile technique used to cut various materials, mainly metals. The technique uses a concentrated laser beam to melt, vaporize or burn away the material. It results in high-precision cuts. The method is particularly useful for complex shapes and detailed patterns that are difficult to achieve with traditional mechanical cutting tools.
Thor Ahlgren AB has a long history of metalworking. We build on decades of experience and tradition, making us a reliable partner for our customers. Our wealth of knowledge in metalworking has been passed down through generations, ensuring the highest quality in every project.
Laser cutting involves the use of a high-energy laser beam, often generated by carbon dioxide (CO2), fiber or ytterbium. The beam is focused through lenses or mirrors to obtain a small spot of high energy density. This energy-dense beam is directed at
workpiece, where it quickly heats and melts the material. By moving the jet along a predetermined path, complex shapes can be cut with great precision.
Thickness: up to ≈ 25 mm with 6-10 kW fiber laser.
Key tips:
Put the focus in the middle of the plate.
Trim the gas pressure for minimal slagging.
Kerf offset ≈ 0.10 mm; oxide skin is ground off before welding/painting.
Reduce the feed rate ≈ 20 % compared to mild steel.
Keep piercing time ≤ 0.2 s for small HAZ.
Oxide-free, hard edge without soft zone.
Avoid O₂ (risk of overheating/annealing).
Short focus length & small nozzle gives narrow HAZ → hardness is preserved.
Use burst piercing and oscillation to prevent overburning.
Cutting speed 0.5-1.0 m/min at 25 mm.
Plasma or gas cutting may be more economical for extremely coarse materials.
Blank, passive edge without post-processing.
For < 4 mm, filtered compressed air can lower the cost (darker cut).
Focus -0.5 mm below the surface, kerf offset 0.10-0.18 mm.
We work with a variety of materials such as steel, stainless steel and aluminum. Our commitment to sustainability is reflected in our efforts to minimize waste. We cut sheet metal thicknesses from 0.35 up to 20 mm. We measure our CO2 footprint and strive for healthy business and a pleasant working environment.
Laser cutting is used in many industries, including automotive, aerospace, electronics, and medical. It is ideal for manufacturing components that require high precision and quality, such as automotive parts, medical implants and electronic circuit boards.
We often manufacture shims and pulse wheels using laser cutting, especially in thinner sheet metal where high dimensional accuracy is required. Laser cutting enables the production of parts with tight tolerances and good repeatability. If necessary, the process is complemented by CNC machining to achieve the right fit or surface finish.
