Cnc 12kw fiber laser cutting processes replace traditional mechanical tools with invisible beams of light. It has the advantages of high precision, fast cutting speed, not limited by cutting patterns, automatic discharge saving materials, smooth cutting, low processing costs, and will gradually improve or replace the traditional metal cutting processing equipment.
So what is the working principle of laser cutting machine? Here is your explanation.
Laser cutting machines are the latest technology and have been widely used in a variety of industries, including metal cutting, glass cutting and engraving. Laser is a kind of light, just like electroluminescence in nature, caused by the transformation of atoms (molecules or ion kites), caused by spontaneous radiation. Although laser light is very light, it is markedly different from ordinary light. Laser only in the original very short period of time depends on the spontaneous emission, the follow-up process is completely determined by the excitation radiation, so the color of the laser is very pure and almost no divergence of directivity, carving machine, luminous intensity is very high, the laser also has high coherence, high strength, high directivity, after laser in laser, It is transmitted through the mirror and irradiated to the processed object through the collection mirror, so that the processed object (surface) receives strong heat and the temperature increases sharply. Due to the high temperature, the point rapidly melts or evaporates, and the trajectory of the laser head is used for machining purposes.
The application of laser processing technology in advertising industry is mainly divided into: laser cutting, laser engraving two working modes, for each working mode, there are some different places in the operation process.
1. Laser engraving
Mainly on the surface of the object, divided into bitmap carving and vector carving:
2. Bitmap carving
We first hang the graphics we need to sculpt and convert them to monochrome BMP format in PHOTOSHOP, then open the graphics file in dedicated laser sculpt and cut software. According to the material we have processed, we can set the appropriate parameters, and then click run, laser engraving machine will be carved according to the dot matrix effect generated by the graphics file.
3. Vector carving
Use Coreldraw, AutoCad, Iluustrator and other typesetting design vector software, export the graphics to PLT, DXF, AI format, marking machine, and then use special laser cutting and engraving software to open the graphics file and transfer it to laser engraving machine processing. Mainly used for advertising board, double color board, plexiglass, processing color paper and other materials.
4 laser cutting we can understand it is the separation of the edge.
For the purpose of such processing, we should first in CORELDRAW, AUTOCAD, pneumatic marking machine in the form of vector line graphics, and then save it as the corresponding PLT, DXF format, with laser cutting machine operating software to open the file, in accordance with the energy and speed and other parameters we can use to set the processing material, After I receive my computer instructions, laser cutting machine will automatically according to the flight path of the software to generate cutting, for example, the existing golden laser cutting machine, according to the computer, can good template, and then directly enter the computer automatic cutting graphics, laser cutting machine usually has its own existing hard disk, can input huge amounts of data. Simple and convenient.
5 characteristics of laser cutting
Laser processing as a new processing method, with its precise processing, rapid, simple operation, high degree of automation, has widely used in leather, textile and garment industry, compared with the traditional way of cutting, laser laser cutting machine is not only the price is low, material consumption, and laser processing of the workpiece without mechanical stress, the effect of cutting products, Precision and cutting speed are very good, it also has operation safety and easy maintenance, etc.
Can work 24 hours a day, with laser laser machine cutting dust-free cloth non-woven cloth not yellow, automatic edge is not loose, not deformed, not hardened, size and precision the same; Can cut any complex shape; High efficiency, low cost, computer design graphics can cut any size of lace of any size, rapid development: Thanks to the combination of laser and computer technology, users can design laser engraving output and can change the engraving at any time as long as they are designed on a computer.
