Information

For the laser cutting machine, it has been used for a long time, and some accessories need to be replaced frequently to ensure the stable performance of the laser cutting machine. These accessories are called wearing parts. The nozzles and lenses are the most frequently changed parts of the laser cutting machine.

 

The focusing lens is a relatively precise optical component, and its cleanliness directly affects the processing performance and quality of the laser cutting machine. Therefore, regular maintenance of the focusing lens is very necessary. Today, I brought you the maintenance process and attention points of focusing lenses. Let ’s look down together ~

 

 

The correct operation process of maintaining the focusing lens of laser cutting machine:

 

1. Take out the focusing lens from the frame: loosen the fastening screws, and then remove the air nozzle and lens barrel in order; first blow off the dust on the lens surface with a blower;

 

2. If you really need to clean the lens, you can only use a lab-grade paper soft cotton ball, dipped in an appropriate amount of acetone or high storage alcohol, and gently rotate it clockwise from the center of the lens to the edge. If necessary, both sides of the lens need to be cleaned. Care should be taken when scrubbing;

 

3. Install the lens barrel and air nozzle, adjust the focal length, and tighten the fastening screws. Be sure to keep the convex surface downward when installing the focusing lens.

 

Pay attention to the following three points when maintaining the focusing lens of the laser cutting machine:

 

1. Focusing lens material is ZnSe (zinc arsenide), which is relatively fragile and afraid of falling. When disassembling and disassembling, pay attention: do not use too much force, and do not collide with hard objects. There is an anti-reflection coating on the surface, which is afraid of pollution, humidity, oiliness, and scratching; therefore, it is required to provide dry and degreasing air during work. Do not directly handle the lens of the focusing lens of the laser cutting machine because of skin oil Will cause permanent damage to the lens surface. Conversely, you can bring gloves and their special sets to operate. For smaller lenses, it is more convenient to use optical tweezers or vacuum tweezers. No matter what method is used to clamp the laser cutting machine focusing lens, it can only be clamped along non-optical surfaces, such as the frosted edge of the mirror plaque.

 

2. In general, the condition of the focusing lens of the laser cutter needs to be checked before use and before and after cleaning. Because most contaminants and surface defects are relatively small in size, we often need magnifying equipment when inspecting lenses. In addition to the magnifying device, sometimes we also need to illuminate the optical surface with a relatively bright light to enhance the specular reflection intensity of surface contaminants and defects, so that it is easier to find the contaminants and defects.

 

3. When cleaning the focus lens of a laser cutter, often use clean wipes and optical grade solvents to prevent damage by other contaminants. Wipes must be moistened with a suitable solvent and must not be used dry. In consideration of softness, the available wipes are Webril wipes of pure cotton or applicators such as cotton balls, lens paper, and cotton swabs.

 

Although it is troublesome to clean and maintain the focusing lens of the laser cutting machine, good cleaning and maintenance operations can prolong the service life of the lens, which can improve efficiency and save costs for enterprises. When the cleanliness is still not high after repeated cleaning, you need to pay attention to replacement to ensure the processing efficiency of the laser cutting machine, so as not to delay production.
