Fiber laser cutting machines have performed exceptionally well in recent years. Compared with traditional cutting methods, laser cutting offers clear advantages in appearance, efficiency, and stability. Although laser cutting may look simple from the outside, how does it actually work? Let’s take a closer look.
How a Fiber Laser Cutting Machine Works
A fiber laser cutting machine uses a fiber laser as its light source. Pumping material is doped into the optical fiber. After a specific wavelength of laser light emitted by a semiconductor laser is coupled into the fiber, the fiber generates laser light.
The laser beam is then focused onto the surface of the workpiece. The area hit by the focused laser spot is instantly melted or vaporized. Through a computer-controlled CNC mechanical system, the laser spot moves across the material to complete automatic cutting and piercing.
A fiber laser cutting machine is a high-tech piece of equipment that combines laser technology, CNC technology, and precision mechanical technology.
Materials a Fiber Laser Cutting Machine Can Process
Fiber laser cutting machines can cut a wide range of metal sheets and tubes. They are mainly used for cutting:
Stainless steel, carbon steel, alloy steel, silicon steel, spring steel, aluminum, aluminum alloy, galvanized sheet, aluminum-zinc coated sheet, pickled sheet, copper, silver, gold, titanium, and other metal sheets and tubes.
Application Areas of Fiber Laser Cutting Machines
Fiber laser cutting machines are widely used in metal sheet processing and many industrial fields, including:
Advertising signs and lettering, high- and low-voltage electrical cabinets, machinery parts, kitchenware, automobiles, machinery manufacturing, metal crafts, saw blades, electrical components, the eyewear industry, spring plates, circuit boards, electric kettles, medical microelectronics, hardware, cutting tools, measuring tools, and other industries.
Features of Fiber Laser Cutting Machines
1. The machine uses an advanced fiber laser, with high photoelectric conversion efficiency and stable performance. Key components can have a service life of up to 100,000 hours.
2. The laser generation process does not require gas. It supports air-assisted cutting, uses fiber transmission, and does not require optical path adjustment.
3. Since the laser is transmitted through optical fiber, no reflective mirrors are needed, which greatly reduces maintenance costs.
4. Compared with other laser systems using different media, fiber laser cutting machines have a smaller focused spot, higher working efficiency, and better processing quality.
5. The structure is simple, and the machine occupies a small floor area.
6. It can work in harsh environments and has strong adaptability to dust, vibration, impact, humidity, and temperature.
7. It offers high precision and fast cutting speed, especially for rapid precision cutting of metal sheets under 4 mm.
Processing Advantages of Fiber Laser Cutting Machines
l High precision, fast cutting speed, narrow kerf, minimal heat-affected zone, and a smooth cutting surface with no burrs.
l The laser cutting head does not contact the material surface, so it does not scratch the workpiece.
l The kerf is very narrow, the heat-affected zone is small, local deformation of the workpiece is minimal, and there is no mechanical deformation.
l It offers strong processing flexibility. It can cut any pattern, as well as tubes and other special-shaped materials.
l It can cut steel plates, stainless steel, aluminum alloy plates, cemented carbide, and other materials of various hardness levels without deformation.
