Understanding Fiber Laser Cutting

Understanding Fiber Laser Cutting

Fiber laser cutting is an advanced metal processing technology that utilizes high-power laser beams to achieve precise and efficient cuts. Unlike traditional CO2 lasers, fiber laser generators generate their beams through an active optical fiber, creating a high-intensity laser with a wavelength of around 1.064 micrometers. This shorter wavelength allows the laser to focus on a smaller spot, resulting in more concentrated power and making it especially effective for cutting metals.
The process begins when the laser beam is directed onto the metal surface, where the high-energy light is absorbed, causing the metal to heat rapidly and melt along the cut path. The cutting head moves along pre-defined paths, precisely guided by computer numerical control (CNC) systems, which allows for intricate and detailed patterns. To assist in the cutting process, a gas such as nitrogen or oxygen is used. This assist gas not only expels molten material from the kerf but also enhances the quality of the cut by preventing oxidation and helping to cool the area.
Fiber laser cutting stands out for its high efficiency, minimal maintenance, and reduced operational costs compared to other methods. With fewer moving parts and a longer-lasting diode, fiber laser generators are highly durable and require less frequent servicing, making them ideal for high-production environments. Moreover, the focused beam of fiber lasers minimizes the heat-affected zone (HAZ), reducing thermal distortion and preserving the integrity of the metal’s properties. This precision, speed, and reliability have made fiber laser cutting a preferred choice for processing a wide range of metals, from thin sheets to thick plates, across industries like automotive, aerospace, electronics, and construction.
