– Effective for Reflective Metals: Their shorter wavelength makes them suitable for cutting reflective materials, such as stainless steel, without risk of damaging the machine.
– Energy-Efficient: Fiber lasers have a higher energy conversion rate, reducing operating costs and making them suitable for continuous, high-volume production.

Máquinas de corte por láser de CO2

CO2 lasers use a gas mixture, typically CO2, to generate the laser beam. These machines are versatile, with specific advantages in steel cutting:
– Broader Beam: This wider beam is particularly useful for cutting thicker steel plates, offering a balance between speed and power.
– Smooth Edge Quality: CO2 lasers can produce smooth edges on thicker steel, minimizing the need for secondary finishing processes.
– Lower Initial Investment: Although CO2 lasers may have higher operating costs due to maintenance needs, their lower initial cost can be an advantage for some businesses.

4. Advantages of Laser Cutting Machines for Steel Metal

Laser cutting machines offer several benefits that make them ideal for working with steel metal. Here’s a closer look at why they are a preferred choice for manufacturers:

Precisión y exactitud

Laser cutting allows for extremely tight tolerances, making it suitable for industries that require precision, such as aerospace and medical devices. The ability to create accurate cuts consistently ensures that parts fit together seamlessly, reducing the time spent on assembly and rework.
