When the focused laser beam strikes the workpiece, the irradiated area rises sharply to melt or vaporize the material. Once the laser beam penetrates the workpiece, the cutting process begins: the laser beam moves along the contour line while melting the material. A stream of jets is usually used to blow the melt away from the cut, leaving a narrow gap between the cutting section and the platen, which is almost as wide as the focused laser beam.
With the maturing and perfection of laser cutting machine technology in recent years, the future laser cutting equipment will be divided into two development roads. One is to upgrade the existing technology, for example, when the thickness of the board is getting thicker and thicker. At the time, the cost is getting lower and lower; the other way is to study new cutting media and cutting methods.
So how to improve the efficiency of laser cutting machine?
1. To further improve the cutting efficiency, to develop a high-efficiency and high-precision CNC laser cutting machine, to improve the cutting speed, not only to improve the quality of the beam, change the cutting process, the more important point is to use a linear motor drive, Give it faster acceleration and movement speed.
2. Develop flexible processing of laser cutting to improve the freedom of laser cutting machine to make it more suitable for the processing of complex curved workpieces. Develop high-precision fiber laser cutting machines to improve their application in 2D and 3D, thereby improving flexible processing.
3. Increase the research of laser cutting technology for large-format slabs, master the technology of far-path laser transmission, the process of slab cutting, the design and manufacturing technology of high-power astronomy laser pointer light paths, and develop large-format large-thick slabs. Laser cutting equipment.
4. Further intelligentization of the cutting machine, further combining the fiber laser with CNC technology, optical technology, and positioning of high-precision workpieces, combining some of the functional components of the laser cutting machine with other processing methods and developing Multi-functional laser processing machine.
Since the brightness of ordinary light sources is not high, the use of light energy for destruction can only be within a very short distance, and the range is also small. After the emergence of lasers, the idea of light weapons could only be realized. The laser can be used as a directional weapon, using a powerful directional laser beam to directly damage the target or invalidate it. It is a high-tech and new concept weapon that uses the enormous energy carried by a high-brightness and strong laser beam to destroy or kill targets such as enemy planes, missiles, satellites, and personnel. Lasers can also be used as short-range tactical weapons. Targets include tanks, aircraft, and short-range missiles within a few kilometers to several tens of kilometers. The forms can be air-to-air, air-to-ground, ground-to-ground, ground-to-air, and ships. Air-to-air, etc., have high accuracy and destructive power within its effective range.
Laser cutting technology to improve the traditional production process, so that mobile phone processing more in line with the requirements of contemporary production standards. On the one hand, laser cutting can increase the value of product creation and reduce production costs. On the other hand, laser cutting of the processing means of liberating products replaces the artificial machinery with automated machinery to create a safer and more reliable production operation mode.
The advantages of laser cutting technology are: high precision: laser cutting energy can be within the millimeter, very fine; effect is good: accurate cutting edge, no melting edge, no grinding; flexibility: you can freely switch the phone film graphics on the computer, Specifications, size, safety and reliability: the work process is not product toxic substances; easy to operate: after a simple training can be used to operate the machine; low operating costs: only consume a small amount of electricity, saving mold costs.
In addition, there are many applications for lasers. In agriculture, laser breeding can be achieved by irradiating a specific dose of a certain amount of time with a laser on a specific part of a crop seed. Laser breeding is safe and easy. After irradiation, it can accelerate the germination of seeds, increase the germination rate, accelerate the maturation and increase the yield. In biological research, cutting cells with a laser knife has become a reality. In environmental protection, laser has become an effective tool for monitoring air pollution. Laser technology has brought great benefits to people. It will be an important area for countries to compete in the new technology revolution.
