How to clean the lens of laser cutter?

Laser lens is divided into focusing lens, protection lens and other types of lenses, in its working process to avoid some pollution, such as water pollution and dust pollution, then the daily maintenance process needs to be cleaned laser lens to ensure the stability of the laser cutting machine. Cleaning the lens, of course, do not want to be in our lives, the lens as clear, we need to pay special attention to this article introduces the laser cutting machine in the cleaning of the laser lens in the correct method.

In the process of cleaning the lens, the only purpose is to remove the contaminants in the lens, and does not cause further contamination and damage to the lens. In order to achieve this purpose, people tend to take a relatively less risky method.

The first step is to apply spherical air to blow off the components floating on the surface of the lens, especially the tiny particles and colloidal flocs on the surface of the lens. However, do not use compressed air from the production line, as this air can contain oil and water droplets that can deepen the contamination of the lens.

The second step is to apply acetone to the lenses for light cleaning. This level of acetone is virtually anhydrous and reduces the likelihood of the lenses becoming contaminated. The cotton ball dipped in acetone must be cleaned in the light of the lens and moved in a circular motion. Once soiled, the cotton ball must be replaced. Cleaning should be done in such a way as to avoid simultaneous wave strips. (If the lens has two coated surfaces, such as a lens, each surface needs to be cleaned in this way). The first side needs to be placed on clean paper for protection).

If acetone does not remove all the dirt, then use acid vinegar cleaning. Acid vinegar cleaning utilizes the solubility of the dirt to achieve removal without causing damage to the optics. This class of vinegar can be (diluted to 50%, or 6% strength) household vinegar or acetic acid. The cleaning procedure consists of washing with acetone, then rubbing the lens back and forth with acetone in vinegar, and then changing the cotton frequently to completely absorb the acid and hydrate.

Note: can only use the check - in - stick cotton swab. Only through the use of high quality medical cotton picking, does not contain any abrasive.

Of course, some pollutants and lens injury can not by washing to remove, especially film burn caused by metal spatter and dirt, to restore the good performance, the only way is to replace the lenses. The correct installation method in the installation process, if the method is not correct, it will make the lens is contaminated. Therefore, the operating procedures should be followed. If a large number of lenses need to be installed and removed, it is necessary to design a fixture to complete the task. The specific fixture can reduce the number of contact lenses, thereby reducing the risk of lens contamination or damage.

In addition, if the lens is not installed correctly, the laser system will not work properly, or even will be damaged. All carbon dioxide laser lenses should be installed in a certain direction. So the user should be sure that the correct direction of the lens.

Mirror is the third common lens, its installation is also very critical. Of course, it is easy to identify the reflector. Obviously, the coated side facing the laser. In general, manufacturers make a mark on the edge to help identify the surface. In general this notation is the arrow, the arrow to the side. Each lens manufacturer has a system that is marked by a lens. Generally speaking, the arrow is opposite to the mirror and the output mirror. For the lens, concave or flat in front of the arrow. Sometimes, the label of the lens will remind the meaning of the mark.

When the lens is properly cleaned and operated, its service life and performance will undoubtedly improve, which is also one of the important ways to improve the life and stability of laser cutter machine. Take some preventive and maintenance measures will be able to ensure that the laser cutting machine work longer, more stable.
