When the laser cutting machine cuts the metal materials, a large amount of gas, slag, and splashes will be released from the working surface, and the protective lens is used to protect the aggregated lens from damage in the cutting process. Of course, it is not only used for laser cutting machines, but also for laser welding, marking, carving and other laser equipment, so the market for protecting lenses is very strong.
Laser cutting machine protect lens, also called laser cutting machine focus lens, laser cutting machine focus lens is a more precise optical element, laser cutting machine protect lens is very important to laser cutting machine, its cleanliness directly affects the processing performance and quality of laser cutting machine. If the lens is not selected properly, it will cause large laser loss, frequent damage to the protective lens, unstable product quality, and serious losses to the enterprise. Although the protective lens of the laser cutting machine belongs to vulnerable parts, in order to improve its utilization rate and reduce the production cost, the purpose of reuse can be realized by cleaning the protective lens regularly. Therefore, the laser cutting machine should always protect the lens for maintenance.
Behind the strong market demand, there are usually uneven product prices and quality. There are dozens to hundreds of protective lenses on the market. The price difference is of course the quality gap. Therefore, it is very important for metal processing enterprises to choose lenses with good quality and low laser loss.
In addition to the matching of overall dimensions, the material and technical parameters of laser antireflection film suitable for the projection lens should be selected according to the actual cutting environment and laser cutting power.
If choosing protective lenses is a mental task, then using them is a technical task.
During the installation and cleaning process of the protective lens, any point of sticking, even the nail has been printed with oil drops, will increase the absorption rate of the lens and reduce the service life. Therefore, lens cleaning should not be ignored:
1. Gloves must be worn during installation, and no fingerprints shall be left;
2. Do not let anything scratch the lens surface;
3. When taking out the lens, hold the edge of the lens with both hands, and do not touch the film layer;
4. Clean the lens with clean tissue paper, test paper and optical grade solvent;
For laser cutting machines, a protective lens is only a small loss, but it can not be ignored. The above selection of lenses and operation precautions, for the majority of laser cutting machine users' reference!
The focus lens of the laser cutting machine belongs to consumables. When it can't reach high cleanliness after cleaning for many times, it needs to be replaced to ensure the processing efficiency of a laser cutting machine, so as to avoid delay in production.
