What Is A Fiber Laser Cutting Machine Used For?

Fiber laser cutting is a laser cutting technology that uses a fiber laser generator as a light source. This technology transmits laser beams through optical fibers, avoiding complex light guide systems such as reflectors, making the optical path simple and the structure stable, and the external optical path maintenance-free. The cutting head of the fiber laser cutting machine contains protective lenses, which reduces the consumption of expensive consumables such as focusing lenses. Light is exported through optical fibers, which simplifies the design of the mechanical system and is easy to integrate with robots or multi-dimensional workbenches. Fiber lasers have the characteristics of small size, light weight, and small footprint. It is a new type of fiber laser cutting technology newly developed internationally.

Working principle:

The basic principle of fiber laser cutting is to use a high-energy-density laser beam to focus on the surface of the workpiece, so that the area irradiated by the ultra-fine focus spot is instantly melted and vaporized, and the spot irradiation position is moved by the CNC mechanical system to achieve automatic cutting. This technology has the characteristics of high precision, fast cutting, no restrictions on cutting patterns, automatic layout to save materials, smooth incisions, and low processing costs. It is gradually improving or replacing traditional metal cutting process equipment.

The advantages of fiber laser cutting technology are its high beam quality, compactness and lightness, high electro-optical conversion efficiency, low power consumption, high output and high reliability, and long life. Since it is composed entirely of optical fibers and has no lenses, there is no need to worry about dust and optical axis deviation, and frequent maintenance is not required, so it is highly maintainable. Fiber laser is rapidly gaining popularity in many industries such as marking, fine processing, welding, and cutting.

Fiber laser cutting has many advantages that make it a popular and widely used cutting process technology:

1. High cutting precision

Laser cutting machine positioning accuracy of 0.05 mm, repeat positioning accuracy of 0.03 mm, can realize the cutting of fine, complex shapes, cutting lines are smooth, clean cuts.

2. Narrow cutting slit of laser cutting machine

The laser beam is focused into a very small point of light, so that the focal point of the high power density, the material is quickly heated to the degree of vaporization, evaporation and the formation of holes. With the beam and the material relative to the linear movement, so that the hole continuously formed a very narrow width of the slit, the width of the cut is generally 0.10-0.20mm.

3. Laser cutting machine cutting surface smooth

Cutting surface without burrs, the surface roughness of the cut is generally controlled within Ra6.5.

4. Laser cutting machine speed

Cutting speed up to 10m/min Maximum positioning speed up to 30m/min Much faster than wire cutting, high productivity, suitable for mass production and efficient processing needs.

5. Good cutting quality of laser cutting machine

Non-contact cutting, the cutting edge by the heat is very small, basically no thermal deformation of the workpiece, completely avoiding the collapse of the material formed when punching and shearing, the cut seam generally do not need secondary processing.

6. No damage to the workpiece

The laser cutting head will not contact with the surface of the material to ensure that the workpiece is not scratched.

7. Unaffected by the shape of the workpiece

Laser processing flexibility is good, can process any shape, can cut tubes and other profiles.

8. Save investment in molds

Laser processing does not require molds, no mold consumption, no need to repair molds, saving the time to replace molds, thus saving the processing costs, reducing production costs, especially suitable for the processing of large products.

9. Material saving

With computer programming, different shapes of products can be cut to maximize the utilization of materials.

10. Improve the speed of sample leaving the factory

Immediately after the formation of product drawings, laser processing can be carried out, the shortest possible time to get the new product in kind.

11. Safety and environmental protection

Laser processing waste less, low noise, clean, safe, no pollution, greatly improve the working environment.

Fiber laser cutting machines are suitable for cutting almost all metal materials, such as stainless steel, carbon steel, alloy steel, silicon steel, spring steel, aluminum, aluminum alloy, galvanized sheet, galvanized sheet, pickled sheet, copper, silver, gold, titanium and other metal sheets and pipes.
