For any equipment that wants to be used for a long time, maintenance is the first element. The long-term use of fiber laser cutting machine will make the machine unstable and prone to failure. Therefore, regular maintenance and inspection should be carried out to ensure the cutting accuracy of the cutting machine and prolong the service life of the machine. So during the use of the fiber laser cutting machine, which accessories and items need to be inspected and cleaned? Below, Leapion Laser Manager will share with you a few points.
The lens of the fiber laser cutting machine is a consumable, especially the optical lens, including protective lens, collimator lens, focusing lens, and more attention should be paid to the usual placement, inspection, and installation, and attention must be paid to prevent the lens from damage and pollution. During the laser cutting process, a large amount of gas and metal impurities will be released from the working surface, and these gas and spatter will cause damage to the lens. When contaminants fall on the surface of the lens, energy will be absorbed from the laser beam, resulting in a thermal lens effect.
During the installation and cleaning of the lens, any sticky matter will increase the absorption rate of the lens and reduce the service life. Therefore, you must pay attention to the following measures during operation:
A. Do not install the lens directly with your fingers, you should wear finger cots or rubber gloves.
B. When installing and removing the lens, do not touch the film, but hold the edge of the lens to install and remove, handle with care, and avoid scratches on the surface of the lens.
C. The lens should be placed in a dry and tidy place for testing and cleaning. To prevent secondary pollution impurities.
D. Lens cleaning method: When cleaning the lens, you must use absolute ethanol or 98% alcohol as a cleaning solution, and lightly dip a small amount of absorbent cotton with alcohol, scrub with directional light, and finally wipe the lens with dry cotton to make the lens bright and transparent.
1. Check whether the position of the cutting head is accurate each time before starting the machine to ensure the accuracy of the working starting point, height and other data of the fiber laser cutting head, and avoid collisions and other accidents during the working process.
2. Before cutting, please confirm the following:
A. Check that the air compressor pressure is not less than 0.8Mpa, and try to open the protective gas and lift gun to check whether it is unblocked.
B. Raise the cutting head first, and then remove the frame to ensure that the cutting piece is within the setting area.
C. Simulate the processing output and confirm whether the cutting sequence is reasonable.
D. Adjust the height of the cutting head to a suitable drilling position.
3. When cutting, observe whether it is cutting at any time. If it is not cutting, first raise the cutting head by hand and stop cutting, check whether the cutting parameters are correct, whether the nozzle and the protective mirror are damaged, adjust them, and then return to the uncut state, then Continue cutting.
4. When cutting, observe whether the cutting piece is turned over or up. If so, take over when the cutting head collides with the workpiece. If the plate is not flat, adjust it to a suitable drilling height (3-5mm) at any time.
5. When cutting, observe whether the cutting head catches fire. If it catches fire, stop cutting, check whether the nozzle is abraded, and judge whether the focus is changing. If it is, increase or decrease the pad according to the situation.
1. Regularly check the loss of the cutting nozzle of the cutting head, and replace it in time if the loss is serious;
2. Check the sharpness of the lens at each part of the cutting head and clean it reasonably;
3. Check the cleanliness and unobstructed conditions of all pipes and joints to ensure that there are no impurities or blockages;
4. Check whether the fixed parts of the cutting head are loose.
The racks of guide rails should be cleaned regularly. First, remove the stains on the guide rail and deal with it. After the material is crushed, add a little cleaning lubricant to the guide rail and move the guide rail so that the clean lubricant is evenly distributed on the guide rail. Be careful not to thicken the lubricating oil (butter). This kind of lubricating oil attached to the guide rail can easily cause adhesion and distortion of the processing materials and dust, thereby damaging the slider and the guide rail.
Clean up the leftover material processed on the workbench. The crawler workbench needs to be used for half a year, and a little clean anti-rust oil is added to the crawler for anti-rust treatment, other workbenches do not need it. Note: The work platform cannot be cleaned easily with water. It is easy to rust the workbench and accelerate the oxidation of the workpiece.
1. Check the temperature of the cooling water. It is recommended that the water temperature be below 35 degrees. Generally, the water inlet of the laser is 22℃≤temperature≤25℃. ; Prevent the circulating water from freezing in winter to prevent the laser tube from freezing and cracking (antifreeze can be added).
2. The water inside the water cooler needs to be replaced regularly. The general replacement frequency is one month, and the specific replacement frequency is based on actual usage. Note: Use distilled water without impurities, such as purified water or mineral water, but not tap water.
When the fan suction is insufficient and the smoke is not smooth, first turn off the power, remove the air inlet and outlet pipes on the fan, remove the dust inside, then turn the fan upside down, and pull the inner blades until they are clean , And then install the fan.
The production workshop where the equipment is placed must be kept dry and well ventilated. The indoor temperature should preferably be between 4-33 degrees. Prevent condensation on the equipment in summer and take anti-freezing measures in winter.
The equipment should be placed far away from places with electromagnetic interference, far away from places with large power and strong earthquakes. The interference of large power will cause the equipment to malfunction from time to time. Pay attention to prevent this situation.
During the operation of the equipment, the operator should always observe the operation of the equipment. If there is an abnormality, immediately stop the operation of the equipment, cut off the power supply, and promptly report to a professional to inspect and repair the equipment. Do not disassemble and repair the equipment privately.
It is necessary to conduct regular statistics on the use of equipment, and if there is a deviation in the effect, it should be replaced in time to prevent it before it happens. If you don't know whether the material can be processed, do not process it, so as to avoid potential dangers and damage the laser equipment.
Of course, the operator must be trained, familiar with the structure, performance and use skills of the fiber laser cutting machine, and master the knowledge of the operating system, in order to better exert the efficiency of the equipment and maximize the efficiency of the equipment. Therefore, in order to have a longer service life of the fiber laser cutting machine and higher cutting accuracy, please pay attention to the cleaning and maintenance of the above five major items.
