For laser cutting machines, they have been in use for a long time and require frequent replacement of some accessories to ensure stable performance. These accessories are called vulnerable parts, among which the nozzle and lens are the most frequently replaced parts of the laser cutting machine.
Focusing lenses are a relatively precise optical element, and their cleanliness directly affects the processing performance and quality of laser cutting machines. Therefore, it is necessary to regularly maintain the focusing lenses. Today, the editor has brought you the maintenance process and precautions for focusing lenses. Let's take a look together~
The correct operation process for maintaining the focusing lenses of the laser cutting machine:
1. Remove the focusing lens from the frame: Loosen the fastening screws, and then remove the air nozzle and lens tube in sequence; First, use a balloon to blow away the dust on the surface of the lens;
If it is indeed necessary to clean the lens, only a laboratory grade paper soft cotton ball can be used, dipped in an appropriate amount of acetone or high alcohol, and gently rotated clockwise from the center of the lens to the edge. When necessary, both sides of the lens need to be cleaned, and cleaning should be done carefully and meticulously;
3. Install the lens tube and nozzle, adjust the focal length, tighten the fastening screws, and make sure to keep the convex surface downward when installing the focusing lens.
The following three points should be noted when maintaining the focusing lenses of the laser cutting machine:
1. The material of the focusing lens is ZnSe (arsenide zinc), which is relatively brittle and afraid of falling; When disassembling, it should be noted that excessive force should not be exerted and there should be no collision with hard objects. There is an anti reflective film on the surface, which is afraid of contamination, moisture, oiliness, and scratching; Therefore, it is required to provide dry and degreased air during work, and do not directly handle the lens of the laser cutting machine focusing lens with your hands, as skin oil can cause permanent damage to the surface of the lens. On the contrary, you can wear gloves and their specialized sets for operation. For smaller lenses, using optical tweezers or vacuum tweezers will be more convenient. No matter what method is used to clamp the laser cutting machine focus lens, it can only be clamped along a non optical surface, such as the frosted edge of the mirror plaque.
In general, it is necessary to check the condition of the laser cutting machine's focusing lens before and after use and cleaning. Due to the relatively small size of most pollutants and surface defects, we often need to use magnifying equipment when inspecting lenses. In addition to magnifying devices, sometimes we also need to use a relatively bright beam of light to illuminate the optical surface, enhancing the specular reflection intensity of surface pollutants and defects, so that pollutants and defects can be more easily detected.
3. When cleaning a laser cutting machine focusing lens, often use clean wiping paper and optical grade solvents to prevent damage by other pollutants. The wiping paper must be moistened with a suitable solvent and must not be used dry. In consideration of softness, the available wiping paper is pure cotton Webril wiping paper or cotton ball, lens paper, and cotton swab applicators.
Although cleaning and maintaining the focusing lenses of laser cutting machines can be a hassle, good cleaning and maintenance operations can extend the service life of the lenses, improve efficiency and save costs for enterprises, which can be said to be twice the result with half the effort. When the cleanliness cannot be achieved after multiple cleaning cycles, it is necessary to pay attention to replacement to ensure the processing efficiency of the laser cutting machine and avoid delaying production.

What are the advantages of laser cutting technology compared to traditional cutting

Nowadays, low-power equipment can also be used for processing, which eliminates the need to borrow someone else's equipment for processing when purchasing a laser cutting machine. The gradual replacement of laser cutting processing mode may be inevitable and also a future market. In terms of its processing effect, the processing effect of a single industry is definitely the best for a single industry, and it can also meet the requirements of this industry to a greater extent. And generally, large-scale manufacturing enterprises will provide equipment operation training to customers who purchase equipment, as long as the company has some technical processing background personnel, it is relatively easy to get started. Therefore, if you want to use laser cutting processing for bosses, you may try to use laser cutting equipment to directly purchase and process, which can help you achieve and solve many problems.
