The laser beam is focused to form a very small point of action with very strong energy, and its application in cutting has many functions. First, the laser energy is converted into amazing thermal energy, which is kept in a very small area, providing a narrow straight edge gap, a small heat-affected zone adjacent to the trim, and small local deformation.
Second, the laser beam does not exert any force on the workpiece. It is a non-contact cutting tool, which means no mechanical deformation of the workpiece, no tool wear, and no tool changeover issues. The cutting material does not need to consider its hardness, that is, the laser cutting ability is not affected by the hardness of the cutting material.
Thirdly, the laser beam has strong controllability, high adaptability and flexibility, convenient combination with automation equipment, and automatic cutting process. Laser cutting offers more flexibility than other conventional machining methods. In addition, as a thermal cutting process, other methods cannot act on a small area like a laser beam, resulting in slits, a large heat-affected zone, and significant workpiece deformation.
Main features of fiber laser cutting machine:
1. Fiber lasers have high electro-optical conversion efficiency and a conversion efficiency of more than 30%. Low-power fiber lasers do not need to be equipped with coolers, but use air-cooled methods, which can greatly save power consumption during operation, save operating costs, and achieve efficient production
2. The laser only needs electric power during operation, and does not need to generate additional gas for the laser, so it has low operation and maintenance costs.
3. The output beam quality of the fiber laser is good, the power density is high, which is very conducive to the absorption of metal materials, and has excellent cutting and welding capabilities, so that the processing cost is low.
4. The optical route of the whole machine is transmitted by optical fiber, no complicated optical guide system such as mirror is needed, the optical path is simple, the structure is stable, and the external optical path is maintenance-free.
5. The cutting head is equipped with a protective mirror, so the consumption of expensive consumables such as focusing mirror is very small.
6. The light is output through the optical fiber, which makes the design of the mechanical system very simple and easy to integrate with the robot or the multi-dimensional workbench.
7. The
fiber laser is small in size, light in weight, can be moved in the working position, occupies a small area, and is easy to operate.
