How to extend the service life of laser cutting machine

Long-term maintenance is a major element for any mechanical product. If you don’t pay attention to maintenance, good mechanical products are not durable, just like a car needs regular maintenance. The same is true for laser equipment. Today, Minsheng Laser Editor Take everyone to understand how the laser cutting machine should be maintained.

The main components of the laser cutting machine can be divided into five types: light source system, dust removal system, transmission system, cooling system, and circuit system. The parts that we usually need to maintain are cooling system (to ensure constant temperature effect) and dust removal system (to ensure dust removal effect) ), optical system (to ensure the quality of the beam), transmission system (mainly need to pay attention to ensure normal operation). In addition, a good working environment and correct operating habits are also conducive to prolonging the service life of the equipment.

　　1. Maintenance of the optical path system　　

After the device has been running for a period of time, some dust will stick to the surface of the lens. This dust will have a great impact on the reflectance of the lens and the transmittance of the lens, which will reduce the power of the laser. At this time, it is necessary to clean the lens. However, you must be careful when cleaning up. The lens is a damaged item. Please handle it gently. Do not touch the lens with sharp or hard objects. The steps and precautions for cleaning the lens are as follows: First, use absorbent cotton dipped in ethanol to wipe carefully along the center to the edge of the lens. The lens needs to be wiped gently, and the surface coating should not be damaged. , Be sure to keep the concave surface down when installing the focusing lens. In addition, the use of ultra-high-speed piercing should be minimized at ordinary times, and the use of conventional piercing can prolong the service life of the focusing lens.

2. Maintenance of dust removal system　　

After long-term use, the dust removal fan will accumulate a lot of dust. If it is not cleaned regularly, it will cause insufficient wind, poor smoke exhaust, affect the exhaust deodorization effect, and generate a lot of noise. Be careful during the cleaning process To be safe, first turn off the power and remove the device on the fan. First remove the inlet and outlet ducts, clean up the dust inside, turn the fan upside down, flip the fan blades inside until it is cleaned, and then install the fan, and keep the fan cleaned once a month.　　

　　3、Maintenance of the transmission system　　

　　During the long-term cutting process of the equipment, smoke and dust will be generated. Small smoke and dust will enter the equipment through the dust cover and adhere to the rail rack. Long-term accumulation will increase the wear of the rail rack. Rack guide rails are relatively precise accessories. Large amounts of dust are deposited on the surfaces of guide rails and linear shafts for a long time, which has a great impact on the processing accuracy of the equipment, and will form pits on the surface of the linear shaft of the guide rails, shortening the service life of the equipment. Therefore, in order to ensure the normal and stable operation of the equipment and ensure the processing quality of the products, it is necessary to do a good job in the daily maintenance of the guide rail and linear axis, and to clean up regularly. After cleaning the dust, grease the rack and lubricate the guide rail with lubricating oil. Each bearing should also be oiled regularly, so as to maintain flexible driving, precise machining, and prolong the service life of the machine tool.

　　4、Maintenance of cooling system　　

The water in the cold water cabinet needs to be replaced regularly. Generally, it needs to be replaced once a week. The quality and temperature of the circulating water directly affect the service life of the laser tube. Generally, manufacturers will require customers to use pure or distilled water, and the water temperature must be controlled below 35 degrees. If you do not change the water for a long time, it is easy to form scale, which will cause the pipeline to block, so you must change the water regularly.

The cooling water is responsible for taking away the heat generated by the laser tube. The higher the water temperature, the lower the light output power (15-20°C water temperature is better); when the water is cut off, the tube end will burst due to the heat in the laser cavity and even damage the laser power supply . Therefore, it is necessary to check whether the cooling water is unblocked at any time. When the water pipe has a hard bend (dead bend) or falls off, and the water pump fails, it must be repaired in time to avoid power drop or even equipment damage.

　　5, working environment requirements　　

　　The production workshop where the equipment is placed should be kept dry and well ventilated. The indoor temperature should be between 4-33 degrees. The equipment should be prevented from condensation in summer and antifreeze measures should be taken in winter. The equipment should be placed far away from places with electromagnetic interference, far away from places with large electricity and strong earthquakes. The interference of large electricity will cause the equipment to malfunction from time to time. Although it is not inevitable, it must be prevented. Therefore, the equipment should not be placed with large electric welding. Nearby equipment, such as machines, giant electric mixers, etc. Not to mention strong vibrations, ground vibrations will obviously cause deviations in the accuracy of laser engraving.

　　6, some other precautions　　

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 without permission. Perform regular statistics on the use of the equipment, and if there is an effect deviation, 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.

　　 As long as the above points are mainly used in ordinary times and used properly, the service life of the equipment will be greatly increased, and the efficiency of work will also increase.
