What is a Fiber Laser Cutting Machine and How Does it Work for Metal Cutting?

A fiber laser cutting machine is a powerful tool used in industrial processes to cut various types of metals with exceptional precision. Its advanced technology has revolutionized the metal fabrication industry, offering fast and accurate results, while reducing operating costs.

How Does a Fiber Laser Cutting Machine Work?

At its core, a fiber laser cutting machine generates a high-intensity laser beam through the amplification of light within an optical fiber. The laser beam is then focused onto the metal surface to be cut using a lens. The heat generated by the laser melts and vaporizes the metal, creating a narrow incision.

The process involves a combination of intense focused light, high-pressure assist gas, and precise motion control to achieve the desired cutting result. The machine operator controls various parameters such as power intensity, cutting speed, and assist gas pressure to optimize the cutting process for different metal thicknesses and types.

Fiber lasers are known for their high energy efficiency and excellent beam quality. They utilize a solid-state laser source, typically a diode pumped with an optical fiber, which produces a laser wavelength highly absorbed by metals. This enables efficient material removal and improved cutting speed.

Advantages of Fiber Laser Cutting Machines for Metal Cutting
