How To Extend the Service Life Of Fiber Laser Cutting Machine

The main components of the laser cutting machine are the circuit system, the transmission system, the cooling system, the light source system, and the dust removal system.In the daily use of the laser cutting machine, the main parts that need to be maintained are 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 (focus on ensuring normal operation) . In addition, if you want to extend the service life of the laser cutting machine, a good working environment and correct operating habits are indispensable.

 Maintenance of Cooling System

First, replace the water inside the water cooler regularly, usually once a week. The water quality and temperature of the circulating water directly affect the service life of the laser tube, so it is recommended to use pure water or distilled water and keep the water temperature below 35°C. If you don’t change the water for a long time, it is easy to form scale, which will block the waterway, so you must change the water regularly.

Second, keep the 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 (15-20°C water temperature is better). 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 pump fails, it must be repaired in time to avoid power drop or even equipment damage.

Maintenance of Dust Removal System

After using the fan of the fiber laser cutting machine for a long time, a lot of dust will accumulate in it, which will affect the exhaust and deodorization effect, and also produce noise.When it is found that the suction power of the fan is insufficient and the smoke exhaust is not smooth, turn off the power first, and remove the air inlet and outlet pipes on the fan to remove the dust inside. Then turn the fan upside down and move the fan blades inside until it is clean. Finally, install the fan. Fan maintenance cycle: about one month.

Maintenance of Optical System

After the fiber laser cutting machine has been working for a period of time, a layer of ash will be stuck on the surface of the lens due to the working environment, thereby reducing the reflectivity of the reflective lens and the light transmittance of the lens, and ultimately affecting the working power of the laser. At this time, use absorbent cotton dipped in ethanol to wipe carefully along the center to the edge of the lens. The lens should be wiped gently, and the surface coating should not be damaged; the wiping process should be handled gently to prevent falling; when installing the focusing lens, be sure to keep the concave surface down. 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.

Maintenance of Transmission System

The laser metal cutting machine will generate smoke and dust during the long-term cutting process, and the fine smoke and dust will enter the equipment through the dust cover and adhere to the rack of the guide rail. If a large amount of dust is deposited on the surface of the guide rail and linear shaft for a long time, it will have a great impact on the processing accuracy of the equipment, and will form pits 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 steadily 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.

Working Environment

The environment of the workshop should be kept dry and well ventilated. The ambient temperature should be between 4°C and 33°C. In summer, prevent condensation on the equipment, and prevent freezing of the laser equipment in winter. The fiber laser metal cutting machine should be far away from electrical equipment sensitive to electromagnetic interference to prevent the equipment from long-term electromagnetic interference. The interference of large power and strong vibration equipment can sometimes cause machine failure, such as large electric welding machines, giant electric mixers, and large power transmission and transformation equipment.
