6 Tips for Metal Cutting with a Fiber Laser

Follow these 6 tips when cutting metal to achieve optimal results.

1. Choose the Right Fiber Laser Cutter

Different types of lasers have different strengths and weaknesses when it comes to cutting metal. Fiber lasers are ideal for cutting a variety of thicknesses but must be paired with the correct lenses, operating systems, etc.

2. Use the Correct Gas

Oxygen or nitrogen is commonly used as the cutting gas in fiber laser cutting. Oxygen is better for cutting thicker metals, while nitrogen is better for thinner materials. The gas helps to prevent oxidation and aids in the cutting process. Some fiber lasers can also cut using only compressed air!

3. Adjust the Fiber Laser cutting Parameters

The laser power, cutting speed, and focal length of the lens are important parameters to adjust when cutting metal. These parameters will depend on the thickness and type of metal being cut, as well as the desired cutting quality and speed.

4. Ensure Proper Ventilation

Laser cutting produces fumes and dust that can be harmful to operators, so it’s important to have a proper enclosure, ventilation, and filtration systems in place.

5. Maintain your Machine

Regular maintenance of the laser cutting machine is essential for ensuring optimal performance and prolonging its lifespan. This includes cleaning the cutting lens, checking the alignment of the laser beam, and replacing worn or damaged components.

6. Follow Safety Precautions

Cutting can be dangerous if proper safety precautions are not followed. Operators should wear protective gear such as safety glasses and gloves, and the work area should be clearly marked and restricted to authorized personnel only.

By following these tips, you can achieve optimal results when using a fiber laser to cut metal.
