Metal laser cutter is a new type of cutting machine product newly invented in the international market in recent years. The cutter product has absolute advantages in cutting speed and mechanical volume. Today we mainly discuss the main advantages of this cutting machine.
First, advanced cutting technology.
The cutting principle of the new fiber laser cutter is a high-performance laser cutter. During the cutting process, the laser emits countless high-performance, high-energy lasers. The huge energy generated by these lasers can immediately evaporate the cutting surface, thereby making The hard interface can be easily removed.
At present, this process is also the most advanced cutting process, and no cutting process can surpass it. This cutting process is very fast in the cutting process, it is easy to cut very thick steel plates in an instant, and the cutting accuracy is also high. . The cutting section accuracy can reach a few millimeters, which can fully meet some high-demand cutting requirements.
Second, the size of the machine itself is very small.
This kind of laser cutter has only one core component, that is, the laser emitting laser. The volume of laser manufacturing is small and will not take up a lot of space like other similar cutting products. Therefore, the overall volume of the machine will be greatly reduced, whether it is in It can reduce a lot of manpower and material resources for us in the process of machinery manufacturing or transportation.
Third, the operation process of the machine is very convenient.
In the process of using fiber laser cutter, all information transmission and energy transmission are transmitted through optical fiber. The biggest advantage of transmission in this way is to save a lot of manpower and material resources, and no light path leakage occurs during the transmission. In addition, before using the device, energy can be easily transferred to the laser without any optical path adjustment.
Fourth, the cutting performance is very stable.
In the cutting process, this laser cutter uses the most stable laser in the world. This kind of laser has a service life of several years. In the process of use, except for human factors, there will be almost no system failure. Therefore, even if this laser cutting machine works under pressure for a long time, it will not produce any vibration or other Adverse effects.
The most common problem in the processing of laser cutter is that they are prone to burrs. Under normal circumstances, irregular metal parts such as sharp corners and burrs will appear when the workpiece surface transitions. However, this does not mean that the occurrence of burrs is acceptable. It directly affects the dimensional accuracy, shape accuracy and surface roughness of the processed parts, thereby reducing product quality and bringing subsequent inspection, assembly, performance and Beautiful. There are many problems, so you should try to avoid glitches.
In most cases, the burrs are not caused by the quality of the laser cutter itself, but because of improper operation by the operator or insufficient maintenance of the cutting machine. In addition, another major cause of failure is the auxiliary gas problem. During laser cutting, the laser beam irradiates the surface of the workpiece to generate extremely high temperatures, thereby rapidly evaporating and evaporating the surface of the workpiece, so as to achieve the purpose of cutting metal. The function of the auxiliary gas is to blow off the residual slag on the surface of the workpiece after the workpiece is irradiated and evaporated by the laser beam.
If this is not done, when the slag cools, a layer of attached burrs will form on the cutting surface of the workpiece. Below, we will summarize the causes of several common burrs and the corresponding solutions to help you avoid the trouble of laser cutting burrs.
Common causes and solutions for burrs
1: The deviation of the up and down position of the focus of the laser beam produced by the laser cutter causes energy not to be concentrated on the workpiece, the workpiece is not completely vaporized, the amount of slag increases, it is not easy to fall off, and it is easy to produce burrs. Solution: Adjust the focus position of the laser beam and adjust it to the best state according to the offset position.
2: The output power of the laser cutter is not enough to effectively evaporate the metal, causing a lot of slag and burrs. Solution: Check whether the laser cutter is working normally. If it is abnormal, it needs to be repaired and maintained in time; if it is normal, you must check whether the output value is correct.
3: The cutting speed of the laser cutter is too slow, which destroys the surface quality of the cut surface and produces burrs. Solution: Adjust and increase the cutting line speed in time to make it reach the normal value.
4: The purity of the auxiliary gas of the laser cutter is not up to the required standard, and it will cause burrs on the workpiece. Solution: Replace auxiliary gas with higher purity.
5: The working time of the laser cutter is too long, which will cause the equipment's working state to be unstable and cause burrs.
Solution: Turn off the laser cutter and restart it after a period of time to let it get a full rest.
Metal laser cutter
is a kind of precision machine tool, and data errors often lead to abnormal operation of its work, so the error is strictly reduced during work. These are the reasons for the burrs of the laser cutter and the specific treatment measures.
