2020 Best Fiber Laser Cutters for Metal Fabrication
Fiber laser cutting machine is a laser metal cutting machine using a fiber laser generator as a light source for sheet metals and metal tubes & metal pipes.
Definition
Fiber laser is a new type of internationally developed fiber laser that outputs a high-energy-density laser beam and gathers it on the surface of the workpiece to instantly melt and vaporize the area illuminated by the ultra-fine focus spot on the workpiece, and move the spot through the CNC mechanical system. Irradiate the position to realize automatic cutting. Compared with the bulky gas laser and solid laser, it has obvious advantages. It has gradually developed into an important candidate in the fields of high-precision laser processing, lidar systems, space technology, laser medicine, and other fields.
The fiber laser cutting machine can be used for plane cutting and bevel cutting, and the edges are neat and smooth. It is suitable for high-precision cutting processing such as metal plates. At the same time, the mechanical arm can perform three-dimensional cutting instead of the original imported five. Axis laser. Compared with the ordinary carbon dioxide laser metal cutting machine, it saves space and gas consumption and has a high photoelectric conversion rate. It is a new product of energy saving and environmental protection and is also one of the world’s leading technological products.
Features
1. The fiber laser machine has high electrical-optical conversion efficiency, and the conversion efficiency is more than 30%. The low-power fiber laser does not need to be equipped with a chiller. The use of air cooling can greatly save power consumption during operation, save operating costs, and achieve the highest production efficiency. ;
2. The laser only needs electrical energy during operation, and does not require additional gas for laser generation, and has the lowest operation and maintenance costs;
3. The fiber laser cutter adopts semiconductor modular and redundant design. There is no optical lens in the resonant cavity, no start-up time, and it has the advantages of no adjustment, maintenance, and high stability. It reduces the cost of accessories and maintenance time, which is traditionally Incomparable by laser;
4. The output wavelength of the fiber laser is 1.064 microns, which is 1/10 of the CO2 wavelength. The output beam has good quality and high power density, which is very conducive to the absorption of metal materials. It has excellent cutting and welding capabilities, resulting in processing costs. lowest;
5. The optical transmission of the whole machine is through an optical fiber, no complicated light guide system such as reflecting mirror is needed, the optical path is simple, the structure is stable, and the external optical path is maintenance-free;
6. The cutting head contains protective lenses so that the consumption of valuable consumables such as focusing lenses is very small;
7. The light is exported through the optical fiber, which makes the design of the mechanical system very simple, and it is very easy to integrate with the robot or multi-dimensional workbench;
8. After the laser is added with the optical shutter, it can be multi-machine, split through the optical fiber, divided into multiple channels and work at the same time, easy to expand the function, convenient and simple upgrade;
9. The fiber laser cutter machine is small in size, light in weight, movable working position, and small footprint;
Advantages
The advantages of fiber laser cutting machine compared with CO2 laser cutting machine:
1. Excellent beam quality: the focus spot is smaller, the cutting line is finer, the working efficiency is higher, and the processing quality is better;
2. Extremely high cutting speed: 2 times of the same power CO2 laser cutting machine;
3. Extremely high stability: It adopts the world’s top imported fiber laser, with stable performance, and the service life of key components can reach 100,000 hours;
4. Very high electro-optical conversion efficiency: the photoelectric conversion efficiency of the fiber laser cutter machine is about 30%, which is 3 times higher than that of CO2 laser cutting machine, energy-saving and environmental protection;
5. Very low cost of use: the power consumption of the whole machine is only 20–30% of the similar CO2 laser cutting machine;
6. Very low maintenance cost: no laser working gas; fiber transmission, no need for reflective lenses; can save a lot of maintenance costs;
7. Convenient product operation and maintenance: optical fiber transmission, no need to adjust the optical path;
8. Super flexible light guide effect: small size, compact structure, easy to flexible processing requirements.
Of course, compared with the carbon dioxide laser metal cutting machine, the cutting range of optical fiber is relatively narrow. Because of the wavelength, it can only cut metal materials, and it is not easy to be absorbed by non-metals, thus affecting its cutting range.
Applications
The surface cut by the fiber laser cutting machine is very smooth, which is difficult to achieve with a CNC punch. Fiber laser cutter machine is widely used in advertising sign production, sheet metal structure, high and low voltage electrical cabinet production, textile machinery parts, kitchen utensils, automobiles, machinery, elevators, electrical parts, springs, subway parts, and other industries.
Trends
Fiber laser cutting machine is a technological revolution of sheet metal fabrication and is also a “machining center” in sheet metal fabrication. The fiber laser metal cutting machine has a high level of flexibility, high cutting speed, high consumption efficiency, and short product consumption cycle, which has won a general market for customers. Laser cutting machine has no cutting force, no deformation during processing; no tool wear, good data compliance; no matter simple or complex parts, it can be cut quickly and precisely by laser at a time; its slit is narrow, the cutting quality is good, and the level of automation is high. The operation is simple, the labor intensity is low, and there is no pollution; automatic cutting layout and nesting can be completed, which improves the application rate of data, has low consumption cost, and good economic efficiency. The effective life of this technology is long. At present, most of the sheets exceeding 2MM thickness in foreign countries use fiber laser cutting machines. Many experts believe that the next 30–40 years will be the golden period for laser cutting technology expansion (the direction of sheet metal fabrication expansion).
