How to Use Fiber Laser Cutting Machines in Metal Fabrication

This post will explore the advantages of fiber laser cutting machines, discuss how they can be applied in metal fabrication, and provide practical tips for successfully integrating this cutting-edge technology into your operations.

How Does Laser Cutting Process Work?

The fiber laser cutting process can be easily understood through these straightforward steps:

1. Design preparation: Make a digital design of the desired shape or pattern using design software like CAD.
2. Machine configuration: Transfer the design to the laser cutting machine’s software and adjust settings like cutting speed, laser strength, and material type.
3. Material setup: Place the metal sheet or workpiece on the machine’s cutting bed, ensuring it is level and secure.
4. Laser initiation: Activate the laser, generating a high-intensity light beam, and direct it at the material’s surface.
5. Cutting action: The laser beam melts, burns, or vaporizes the material following the specified pattern. The machine’s software guides the laser head’s movement to trace the design precisely.
6. Gas assistance: An assist gas, like nitrogen or oxygen, is blown at the cutting zone to clear away molten or vaporized material and maintain a clean cutting edge.
7. Completed cut: When the cutting process is finished, the machine stops and deactivates the laser beam.
8. Finished product: Gently remove the cut piece from the machine, examine it for quality and precision, and perform any necessary post-processing tasks, like cleaning or deburring.

What Role Do Laser Beam and Cutting Head Play in Fiber Laser Cutting Machines

We can break down the roles into two different categories: 

Laser Beam in Fiber Laser Cutting Machines

The laser beam is a vital component of fiber laser-cutting machines. It generates the high-intensity light required to cut through various materials. In a fiber laser cutting machine, the laser beam is produced within the fiber optic cable and directed toward the material surface.

The focused beam has a high energy density, enabling it to melt, burn, or vaporize the material with precision and speed. The laser beam’s characteristics, such as its wavelength and power, determine the machine’s cutting efficiency and the types of materials it can process.

Cutting Head in Fiber Laser Cutting Machines

The cutting head is another crucial element of fiber laser cutting machines. It serves several essential functions, including:

• Focusing the laser beam: The cutting head contains a lens or a series of lenses that concentrate the laser beam onto a small spot on the material’s surface. This focusing action increases the energy density of the beam, enabling it to cut through the material more effectively.
• Controlling the assist gas: The cutting head directs the assist gas, such as nitrogen or oxygen, onto the cutting area. The assist gas helps to remove molten or vaporized material from the cut, ensuring clean and precise edges.
• Movement and positioning: The cutting head is attached to a motion system, such as a gantry or a robotic arm, which allows it to move along the X, Y, and Z axes. This movement system enables the cutting head to follow the designated path accurately, ensuring the final cut piece matches the original design.

Together, the laser beam and cutting head work to provide precise, efficient, and high-quality cutting in fiber laser cutting machines. Look at this blog to learn how to choose cutting heads for your business.

What Factors Affect the Laser Cutting Process

A few key aspects can impact the laser cutting process, affecting the overall performance and quality of the final cut. These crucial factors are:

1. Material thickness and kind: The material’s thickness and type play a significant role in how effective the laser cutting will be. Generally, thicker materials need more laser power and slower cutting speeds. Different materials, like metals, might be more suitable for laser cutting than others, such as wood or plastic.
2. Laser beam focus and quality: The laser beam’s focus and quality are essential for achieving clean and efficient cuts. A properly focused beam with high energy density cuts materials more effectively, resulting in better edges and reduced waste. Maintaining the laser’s focus and beam quality throughout the cutting process is critical for the best results.
3. Assist gas pressure and cutting speed: The assist gas pressure and cutting speed also influence the laser cutting process. Higher gas pressure helps clear molten or vaporized material more effectively, leading to cleaner cuts. However, too much pressure might cause the material to warp or become distorted. The cutting speed must be well-balanced to ensure accurate cuts without sacrificing efficiency. A slow cutting speed can cause too much heat, potentially damaging the material, while a fast cutting speed may lead to incomplete cuts or less precision.
