Working principle and technical advantages of fiber laser cutting machine

(Click 336 )

The working principle of fiber laser cutting machine is based on the high energy density characteristics of laser. The high-energy laser beam generated by the laser is focused on the surface of the workpiece through the optical focusing system, instantly heating the material to the melting point or even boiling point, causing the material to melt and vaporize rapidly. At the same time, with the help of the blowing force of the auxiliary gas, the melted and vaporized material is blown away from the cutting area to form an incision. In the processing of precision structural parts, this non-contact processing method avoids the problems of tool wear and deformation in traditional mechanical processing, and greatly improves the processing accuracy.

Fiber laser cutting machine shows many significant advantages in the processing of precision structural parts. First of all, it is high precision. The laser beam spot diameter is extremely small, which can achieve micron-level or even sub-micron-level processing accuracy, and can meet the processing requirements of complex shapes and small sizes of precision structural parts. For example, in the processing of electronic chip packaging structural parts, it is necessary to cut fine micron-level slots. The laser cutting machine can accurately complete the task to ensure that the chip performance is not affected.

The second is high efficiency. The laser cutting speed is fast, and there is no need to replace complex fixtures, which can realize automatic continuous processing. Taking the mass production of precision metal middle frames of mobile phones as an example, laser cutting machines can complete a large number of cutting tasks in a short time, greatly improving production efficiency.

In addition, it is highly flexible. Fiber laser cutting machines can easily realize the processing of various complex graphics through programming. Whether it is regular graphics or irregular special-shaped structural parts, they can quickly complete the cutting, greatly shortening the product research and development and production cycle. Finally, the heat-affected zone is small, the heat action time of laser cutting is short, and the thermal deformation of the material is small, which can effectively ensure the dimensional accuracy and surface quality of precision structural parts and reduce subsequent processing procedures.
