What are the advantages and disadvantages of laser engraving machine compared with ordinary engraving machine? With the development of laser technology, laser engraving machines have many advantages over traditional processing methods. For example, a laser engraving machine can improve the efficiency of engraving and make the surface of the engraving place smooth and round; laser etching has high precision, fast speed and wide application range.
1. The application range of laser engraving machine is very wide
Laser engraving machine can process most metal or non-metal materials. Can be divided into: non-metal laser engraving machine and metal laser engraving machine. Among them, the carbon dioxide laser engraving machine in the non-metal laser engraving machine can engrave and cut almost any non-metal material.
2. laser engraving machine processing effect is good
A. High engraving accuracy
The processing accuracy of laser engraving machine can reach 0.02mm, and it can carry out high-speed engraving and cutting according to computer-related images and patterns.
B. Narrow cut
The laser beam of the laser engraving machine is focused into a small spot, so that the focus can reach a high power density. The material is quickly heated to the degree of vaporization and evaporates to form a hole.
C. the carving surface is smooth, round and free of burrs
The surface of the processed material will be very clean and smooth. After most materials such as steel, aluminum, alloy, etc. are processed by laser, there will be no obvious deformation or damage on the surface, and the appearance and characteristics of the original material are maintained to the greatest extent.
D. Non-contact machining
Laser is a kind of non-contact processing, does not need to fix the workpiece, does not produce mechanical extrusion or mechanical stress on the material, the material deformation is very small, and a large amount of material deformation can be controlled within a few percent of a millimeter.
E. the processing effect is the same
Laser engraving machine can ensure that the results of laser processing products in the same batch are completely consistent.
F. Fast processing speed
Laser engraving machine can process at high speed. For thinner stainless steel materials, the processing speed can reach 10-20m/min, and will vary according to different materials and thicknesses.
3. energy saving and environmental protection
The beam and spot diameter of the laser engraving machine is small, generally less than 0.5mm. The engraving and cutting process saves materials, is safe and sanitary; and the laser is noise-free and pollution-free.
4. Other advantages
A. The precision workbench can be used for fine micromachining and can mark the surface of "millimeter-level" parts;
B. Use a microscope or camera system to observe or monitor the condition of the engraved surface;
C. Prism and mirror system can be used to focus the beam on the inner surface or inclined surface of the workpiece for etching;
D. the internal parts can be carved through light-transmitting materials (such as quartz, glass);
E. During laser etching, X-rays will not be generated like electron beam bombardment and other engraving methods, and will not be interfered by electric and magnetic fields;
F. the operation is simple, the automatic engraving can be realized by using the numerical control technology, and the engraving sequence can be used freely. It can be used for high-speed and efficient engraving of parts on the production line, and can be used as a part of a flexible processing system.
