Introduction to the characteristics of different laser cutting machines

The laser cutting machine is a laser beam emitted from the laser, which is focused into a high power density laser beam by the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point, while a high pressure gas coaxial to the beam blows the molten or vaporised metal away. As the beam moves relative to the workpiece, it eventually causes the material to form a cut, thus achieving the purpose of cutting.

 

The laser cutting process uses an invisible light beam instead of a traditional mechanical knife, which has the characteristics of high precision, fast cutting, not limited to cutting pattern restrictions, automatic nesting to save material, smooth kerf, low processing costs, etc. It will gradually improve or replace the traditional metal cutting process equipment. The mechanical part of the laser head has no contact with the workpiece and will not cause scratches on the surface of the workpiece during work; laser cutting speed is fast, the kerf is smooth and flat and generally no subsequent processing is required; the heat-affected zone of cutting is small, the plate deformation is small and the cutting slit is narrow (0.1mm~0.3mm); there is no mechanical stress in the kerf and no shear burr; the processing accuracy is high, the repeatability is good and the material surface is not damaged; the CNC programming allows processing Arbitrary planes, can cut whole plates with large widths without opening moulds, economical and time-saving.

 

Fiber laser cutting machine which can do both flat cutting and bevel cutting processing, and the edge is neat and smooth, suitable for metal plate and other high-precision cutting processing. The fiber laser cutting machine is more space-saving and gas-consuming than ordinary CO2 laser cutting machine, with high photoelectric conversion rate, which is a new product of energy-saving and environmental protection, and one of the world's leading technology products.

 

1) Excellent beam quality: smaller focused spot, finer cutting lines, higher efficiency and better processing quality.

2) Extremely high cutting speed: twice as fast as the equivalent power CO2 laser cutting machine.

3) Extremely high stability: the use of the world's top-class fibre laser, stable performance, the service life of key components up to 100,000 hours.

4) Very high electro-optical conversion efficiency: the photoelectric conversion efficiency of fiber laser cutting machine reaches about 40-50%, which is three times higher than that of CO2 laser cutting machine, energy saving and environmental protection.

5) Very low cost of use: the power consumption of the fiber laser cutting machine is only 20-30% of similar CO2 laser cutting machines.

6) Very low maintenance costs: no laser working gas; fiber optic transmission, no reflector lens; can save a lot of maintenance costs.

7) Easy operation and maintenance of the product: fiber optic transmission, no need to adjust the optical path.

8) Superb flexible light-guiding effect: compact size and structure, easy for flexible processing requirements.

 

Of course, compared to CO2 laser cutting machines, the cutting range of optical fibres is relatively narrow. Because of its wavelength, it can only cut metallic materials and is not easily absorbed by non-metals, thus affecting its cutting range.
