How does Manhart (Guangdong) CNC Machine Tool Co., Ltd. determine that the lens of the laser cutting machine needs to be cleaned?

To determine whether the lens of the laser cutting machine needs to be cleaned, the following methods can be used:
Firstly, the surface of the lens can be observed with the naked eye for impurities, dirt, etc. When observed directly under lighting, some large impurities or stains are usually easily visible.
Secondly, using the cotton swab method is also an effective detection method. Roll the fine cotton swab into a slender handle, dip it in cleaning agent or alcohol, gently wipe the surface of the lens, and then observe the degree of stains on the cotton swab. If there are obvious stains on the cotton swab, it indicates that the lens needs to be cleaned.
In addition, the red light detection method can be used to check the cleanliness of the lenses. Prepare a single-layer nozzle with a diameter of more than 2.0mm and white paper. After turning on, check if the red light is clear. If there are clearly defined black spots or irregular black objects in the red light, the lens is dirty and needs to be cleaned before cutting and debugging.
Finally, according to the usage of the equipment, a fixed cleaning cycle can also be set. Generally speaking, cleaning once a week is a suitable frequency, but the specific frequency needs to be adjusted according to actual usage.
Please note that before cleaning the lenses, it is necessary to turn off the laser and wait for a period of time until the temperature of the lenses is close to room temperature before cleaning to avoid thermal shock to the lenses. Meanwhile, during the cleaning process, strong vibrations or shaking of the lens should be avoided to avoid scratching the surface.
In summary, by observing with the naked eye, cotton swab method, red light detection method, and setting the cleaning cycle, it can be determined whether the lens of the laser cutting machine needs to be cleaned. Regular cleaning of lenses can ensure the normal operation and cutting quality of the laser cutting machine.
