Several working methods of fiber laser machine(1)

Several working methods of fiber laser machine


Laser engraving:

It is mainly carried out on the surface of the object, divided into bitmap carving and vector carving

Bitmap carving: first, we use Photoshop to hang the engraving graphics and convert them to monochrome BMP format, and then open the graphics file in the special laser carving and cutting software. According to the materials we process, we can set the appropriate parameters, and then click Run, the laser engraving machine will carve according to the lattice effect produced by the graphic file.

Vector engraving: use vector software such as CorelDRAW, AutoCAD, illustrator and other typesetting design, and export the graphics to PLT, DXF, AI format, marking machine, then open the graphics file with special laser cutting engraving software, and transfer it to the laser engraving machine for processing.

Laser cutting:

We can understand it as a separation on the edge. For such processing purposes, we should first make the graphics into vector lines in CorelDRAW and AutoCAD, pneumatic marking machine, and then save them in the corresponding PLT and DXF formats, open the file with the operation software of laser cutting machine, and then run it according to the setting of energy, speed and other parameters of the processed materials. The laser cutting machine will cut automatically according to the flight path generated by the software after receiving the instruction of the computer. For example, the existing laser cutting machine can draw a good template according to the computer, and then directly input the computer to automatically cut the graphics.

Laser melt cutting:

In laser melting cutting, the melted material is ejected by means of airflow after the workpiece is melted locally. Because the transfer of material only occurs in its liquid state, this process is called laser melting cutting. 

The laser beam with high purity inert cutting gas impels the melted material to leave the slit, while the gas itself does not participate in the cutting. Laser melting cutting can get higher cutting speed than gasification cutting. The energy required for gasification is usually higher than the energy required to melt the material. In laser melting cutting, the laser beam is only partially absorbed. The maximum cutting speed increases with the increase of laser power, and decreases almost inversely with the increase of plate thickness and material melting temperature. In the case of a certain laser power, the limiting factor is the air pressure at the slit and the thermal conductivity of the material. For iron and titanium materials, laser melt cutting can obtain non oxidation notches. For steel materials, the laser power density is between 104w / cm2 and 105W / cm2.

The fiber laser machine produced by Zaozhuang Make Machinery Co., Ltd. can cut carbon steel, stainless steel, copper, aluminum and other materials with the method of laser cutting. It can cut the carbon steel with the thickest 25 mm. If you are interested in our products, you can come to consult us!
