Do you know anything about laser cutters?
With the development of laser cutting technology, laser cutting is applied widely, and more and more suitable materials are used.
Here are some bits of knowledge share with you:
What is the working principle?
Laser cutting uses a focused high power density laser beam to illuminate the workpiece, making the irradiated material rapidly melt, vaporize, ablate or reach the burning point, and blow out the molten material by high-speed airflow coaxial with the beam at the same time. It is a thermal cutting method to cut the workpiece by moving the spot irradiation position through the numerical control mechanical system.
Any dangerous operation?
Laser cutting is a very environmentally friendly cutting method, which generally does no harm to the body.
Compared with ion cutting and oxygen cutting, laser cutting produces less dust, weak light, and less noise.
However, if you do not follow the correct method of operation, it is easy to accidentally hurt others.
What are the factors that affect the accuracy?
There are many factors that affect the accuracy of laser cutting, some of which are determined by the equipment itself, such as the accuracy of the mechanical system, the degree of vibration of the worktable, the quality of the laser beam, the influence of auxiliary gas and nozzles, and some of the inherent factors of the material. such as the physical and chemical properties of the material, the reflectivity of the material, and so on.
Some factors are selected according to the specific processing object and the quality requirements of users, and adjusted accordingly to determine the relevant parameters, such as output power, focus position, cutting speed and auxiliary gas, and so on.
What are the types of lasers and the difference between them?
At present, the lasers used in laser processing and manufacturing mainly include CO2 laser, YAG laser, fiber laser and so on.
Among them, high-power CO2 laser and YAG laser are widely used in secret processing, and the fiber laser with optical fiber matrix has obvious advantages in reducing threshold, oscillating wavelength range, wavelength tunability and so on, so it has become a new technology in the laser field.
What is the cutting thickness?
At present, the thickness of the laser cutting machine is generally no more than 50mm. Compared with other cutting methods, it has obvious advantages for cutting materials with accurate sizes below 20mm.
At present, the cutting thickness of Bond laser has been able to cut 130mm, leading the world.
What are the applications?
Laser cutting machine is widely used in automobile manufacturing, kitchen utensils industry, sheet metal processing, advertising industry, machinery manufacturing, chassis cabinets, elevator manufacturing, fitness equipment, and other industries because of its advantages such as wide cutting range, high cutting speed, narrow slit, good cutting quality, small heat-affected zone, flexible processing and so on.
But the general laser cutting machine is mainly divided into metal cutting and non-metal cutting, there are mixed cutting, metal and non-metal can be used, but not recommended.
The types of laser cutting machines produced by different laser cutting machine manufacturing enterprises are also different, and the concentration is also different.
In the future, optical fiber laser cutting will gradually replace the traditional processing technology and become a more efficient and faster processing method. More and more manufactures has continuously launched 20000W and 30000W metal laser cutting machines, mastering the core technology of high-power laser cutting machines and leading the global high-power laser cutting equipment to be made in China and praised by the world.
