The lens of the laser cutting machine can actually be reused. However, if the protection is not good, or the maintenance is not done properly, it is easy to cause the lens to burn out, crack, or burn out. Today Leapion Laser introduces how the lens of the laser cutting machine is always damaged, what should I do?
In the process of laser cutting machine cutting, every important step is inseparable from optical lenses. The laser cutting machine uses the energy of the laser beam to cut, and the original beam emitted by the laser is focused through the optical lens to form a high-density light spot to achieve the purpose of cutting.
1. Protective lens burst
In the process of laser cutting machine, the energy generated is very large, and the temperature will be relatively high. If the protective lens has moisture, the protective lens with very high temperature will burst immediately when it encounters moisture.
2. The quality of the lens itself
Some manufacturers use ordinary or inferior lenses in order to save costs. In addition, the lenses themselves are vulnerable accessories. After receiving the goods, disassembly and assembly accidentally touch the lenses, or the collision between the goods and other items will also have a certain impact on the lenses.
3. The cutting head of the laser cutting machine itself has poor sealing effect.
4. Wrongly replace the protective mirror window box.
5. The cleaning method of the protective mirror is incorrect.
6. Unqualified consumable parts of the cutting head are used.
7. Improper operation of laser cutting machine.
8. Wrong selection of laser cutting process data parameters.
9. The installation method of the protective mirror in the cutting head is incorrect.
1. When operating the laser cutting machine, operate it correctly in strict accordance with the requirements of the manual to reduce the negative impact on the protective mirror caused by improper operation.
2. In the process of installing and replacing the protective mirror, try to keep the cutting head in a horizontal state, install the protective mirror into the cutting head and lock it. Avoid the tilting of the cutting head, which may cause dust to fall into it due to careless installation.
3. After the work is completed every day, it is necessary to remove dust, the dust must be meticulous, and be careful when cleaning the lens, and clean the lens reasonably and correctly.
When replacing a new lens, it must be dusted before use.
4. Check whether there are stains and liquids on the lens every day. When checking the lens, also check whether the air compressor dryer is running normally.
5. It is very important to select the appropriate process cutting parameters. Because different cutting processes correspond to different cutting power, type of sheet to be cut, thickness of sheet to be cut, and assist gas are different.
6. The usage rate of the lens, the thickness of the sheet to be cut, and the stability of the air pressure all have a certain impact on the lens. When using the cutting machine, you can increase the blowing delay, and pay attention to adjusting the focus when cutting the workpiece.
7. The number of perforations in the corresponding time should be remembered, because the higher the output frequency, the easier it is to perforate and sputter the lens. Before perforation, the time must be set.
