Because of its monochromaticity, coherence, and parallelism, lasers are especially suitable for material processing. Laser processing is an area with the best development prospects for laser applications, and more than 20 laser processing technologies have been developed. The space control and time control of the laser are very good, and the material, shape, size and delivery environment of the processing object have great freedom, and it is especially suitable for automatic processing. The combination of laser processing system and computer numerical control technology can form high-efficiency automatic processing equipment, which has become a key technology for enterprises to implement timely production, opening up a broad prospect for high-quality, efficient and low-cost processing and production.
Currently mature laser processing technologies include: laser rapid prototyping technology, laser welding technology, laser drilling technology, laser cutting technology, laser marking technology, laser deweighting balance technology, laser etching technology, laser fine-tuning technology, laser storage technology, Laser scribing technology, laser cleaning technology, laser heat treatment and surface treatment technology.
Laser rapid prototyping technology integrates the latest achievements of laser technology, CAD/CAM technology and material technology. According to the CAD model of the part, the photosensitive polymer material is cured layer by layer with a laser beam, and accurately stacked into a sample, without the need for molds and tools. Quickly and accurately manufacture parts with complex shapes. This technology has been widely used in aerospace, electronics, automotive and other industrial fields.
Laser cutting technology is widely used in the processing of metal and non-metal materials, which can greatly reduce processing time, reduce processing costs, and improve workpiece quality. Pulsed lasers are suitable for metallic materials, and continuous lasers are suitable for non-metallic materials. The latter is an important application field of laser cutting technology. Modern lasers have become the “sword” of “cutting iron like mud” that people dream of pursuing.
Laser welding technology has a molten pool purification effect, can clean the welding metal, and is suitable for welding between the same and different metal materials. Laser welding has high energy density, which is particularly advantageous for welding metals with high melting point, high reflectivity, high thermal conductivity and very different physical properties. Laser welding uses a smaller laser beam than when cutting metal to melt the material without vaporizing it and become a continuous solid structure after cooling.
The application of lasers in the industrial field has limitations and shortcomings. For example, the use of lasers to cut food and plywood is unsuccessful. The food is burned at the same time it is cut, and cutting plywood is far from economical.
Laser marking technology is one of the largest application areas of laser processing. Laser marking is the use of high-energy-density laser to locally irradiate the workpiece. It is a marking method in which the surface material vaporizes or undergoes a chemical reaction of color change, thereby leaving a permanent mark. Laser marking can produce various characters, symbols and patterns, etc., and the size of the characters can range from millimeters to micrometers, which has special significance for the anti-counterfeiting of products.
Excimer laser marking is a new technology developed in recent years. It is especially suitable for metal marking and can achieve sub-micron marking. It has been widely used in the microelectronics industry and bioengineering.
