Introduction to the working principle and characteristics of fiber laser cutting machine

Laser cutting machine has been widely used in automotive, machinery, electricity, hardware and other electrical appliances and other fields, because of its fast speed, narrow slit, small heat-affected zone, good verticality of the slit edge, cutting edge lubrication and loved by the majority of manufacturers. So as a laser cutting machine is also widely used in the fiber laser cutting machine, so how much do you know about fiber laser cutting machine? Here to introduce you to the processing principle and characteristics of fiber laser cutting machine.

The processing principle of fiber laser cutting machine at work
Fiber laser cutting machine in the work, the laser beam will be focused into a very small spot, so that the spot at a very high power density, the spot under the material is quickly heated to vaporization temperature, evaporation to form a hole, chasing the speed of light and the material relative to the movement of the hole continuous, forming a very narrow width of the slit, so as to achieve the processing requirements.

Technical features of fiber laser cutting machine
1.Good cutting quality. Due to the small laser spot, high energy density, a laser cutting can obtain a better cutting quality. Laser cutting slit is generally in 0.1-0.2mm, the heat-affected zone width is very small, the geometry of the cut is good, the cut cross-section presents a more regular rectangle. Laser cutting of the cutting surface without burr, surface roughness R can generally reach 12.5um or more, laser cutting even as the last processing process, the cutting surface generally does not require further processing can be directly welded, parts can be used directly.

2.Fast cutting speed. As the laser cutting, the workpiece heat-affected zone is small, the deformation is very small, no need to clamp fixed, both to save the clamping fixture, and save the auxiliary time such as clamping.

3.More types of materials can be cut. Compared with plasma cutting and other cutting methods, laser cutting can cut a wider variety of materials, including metal, non-metal, metal-based and non-metal-based composite materials. For different materials, due to the material's own thermophysical properties and the absorption rate of the laser is different, it shows different laser cutting adaptability.

4.Suitable for the processing of large products. Laser processing does not require any mold, and laser processing completely avoids the collapsed edge formed when punching and shearing materials, which can significantly reduce the production cost of enterprises and improve the grade of products.

5.Clean, safe, no pollution. Laser cutting process noise is low, vibration is small, no pollution, greatly improving the working environment of the operator.

6.Not easy to be electromagnetic interference. Unlike electron beam processing, laser processing is not sensitive to electromagnetic field interference and does not require a vacuum environment.
