How to improve the service life of laser cutting machine?

The main components of the laser cutting machine are circuit system, transmission system, cooling system, light source system and dust removal system. The daily maintenance focuses on the cooling system (to ensure the constant temperature effect), the dust removal system (to ensure the dust removal effect), the optical path system (to ensure the beam quality), and the transmission system (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.

The water inside the water cooler needs to be replaced regularly, and the replacement frequency is generally a week. The quality and temperature of the circulating water directly affect the service life of the laser tube. It is recommended to use purified water or distilled water, and the water temperature should be controlled below 35°C. If the water is not changed for a long time, it is easy to form scale, which will block the waterway, and the water needs to be changed regularly.

Second, keep water flowing at all times. 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 (preferably 15-20°C); when the water is cut off, the tube end will burst due to heat accumulation 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 is hard bend (dead bend) or falls off, and the water pump fails, it must be repaired in time to avoid power failure or even equipment damage.

After the fan is used for a long time, a large amount of dust will accumulate, which will affect the exhaust and deodorization effect, and also produce noise. If the fan's suction is insufficient and the exhaust is not smooth, turn off the power first, remove the air inlet and outlet pipes from the fan, remove the dust inside, and then turn the fan upside down, flip the blades inside until it is clean, and then install the fan. Fan maintenance cycle: about one month.

After the machine has been working for a period of time, due to the working environment, a layer of dust will stick to the surface of the mirror, which will reduce the reflectivity of the mirror and the transmittance of the lens, and ultimately affect the laser Working power. At this time, use absorbent cotton to soak in ethanol, and carefully wipe along the center to the edge of the lens. The lens should be wiped gently, not to damage the surface coating; when wiping, be careful to prevent it from falling; when installing the focusing lens, make sure that the concave surface is facing down. In addition, the use of ultra-high-speed punching should be minimized as much as possible, and the use of conventional punching can extend the service life of the focusing lens.

The equipment will generate smoke and dust during the long-term cutting process. Small smoke and dust will enter the equipment through the dust cover and adhere to the guide frame. Long-term accumulation will increase the wear of the guide frame. The rack rail is a relatively accurate accessory. Dust deposited on the surface of the guide rail and linear shaft for a long time has a great impact on the processing accuracy of the equipment, and will form corrosion spots on the surface of the linear shaft of the guide rail, thereby shortening the service life of the equipment. Therefore, in order to make the equipment work normally and stably and ensure the processing quality of the products, it is necessary to do a good job of daily maintenance of the guide rail and linear axis, and regular dust removal and cleaning. After cleaning the dust, lubricate the rack and lubricate the guide rails with lubricating oil. All bearings should be refueled regularly to maintain flexible driving and machining accuracy and extend the service life of the machine tool.

The workshop environment should be kept dry and well ventilated, and the ambient temperature should be between 4℃-33℃. Take care to prevent the equipment from condensing in summer and to prevent freezing of laser equipment in winter.

The equipment should be far away from electrical equipment sensitive to electromagnetic interference to prevent the equipment from being exposed to electromagnetic interference for a long time. Stay away from sudden interference from high-power, strong-vibrating equipment, which can sometimes cause machine failure. Although it is rare, it should be avoided as much as possible. Therefore, such as large electric welding machines, giant electric mixers and large power transmission and transformation equipment. , Should stay away. Strong vibration equipment is self-evident, such as the vibration caused by forging presses and short-distance motor vehicles. The obvious shaking of the ground is not conducive to accurate carving.

During the operation of the equipment, the operator must observe the working conditions of the equipment at any time. If there is any abnormality, immediately cut off all power supplies, troubleshoot the fault in time or report to the supervisor, and actively Take corresponding measures. Regularly check the use of the machine, and make regular records of all parts of the laser cutting machine. If the effect is not good, replace it in time, and take precautions.

Do not process the material until it can be irradiated or heated by the laser to avoid the potential hazards of smoke and steam and damage to the laser equipment.

If you use the above maintenance skills well, I believe your equipment will last longer and work more efficiently!
