These machines make use of distinct types of lasers, each suited for specific applications due to their unique characteristics. This segment will delve into the details of the primary types of steel laser cutting machines, including their characteristics and applications.
CO2 Laser Cutting Machines
CO2 lasers are one of the most commonly used lasers in steel cutting. They work by emitting light at a wavelength of 10.6 microns. CO2 lasers operate at their optimal rate with clean steel surfaces. When dealing with dirty or rusted steel, it can lead to less efficient cutting, potentially requiring extensive cleaning prior to the cutting process. This type of laser cutting machine excels with applications such as metal fabrication, cutting of steel sheets and profiles, and marking on metal.

- High precision: can ensure minimal cutting width.
- Cost-effective for mass production.
Fiber Laser Cutting Machines
Fiber lasers operate on a shorter wavelength (around 1 micron) than CO2 lasers, allowing for deeper penetration. They utilize a fiber-optic cable for the delivery of the laser beam, making adjustments to the beam possible without compromising its quality. Due to the high cutting precision, they’re suitable for complex designs or intricate cuts with small tolerances. They operate effectively within a relatively high-temperature environment with minimal maintenance, ideal for applications in industries with strict cleanliness standards or with very thick steel sheets.
