How to maintain the laser cutter machine to extend the service life?
The main components of the laser cutting machine are circuit system, transmission system, cooling system, light source system and dust removal system. The main points that need to be maintained in daily life are heat dissipation system (to ensure constant temperature effect), dust removal system (to ensure dust removal effect), optical path system (to ensure beam quality), and transmission system (focus on ensuring normal operation). In addition, a good working environment and correct operating habits also help to extend the service life of the equipment.
1. Maintenance of cooling system.
The water in the water dispenser needs to be replaced regularly, and the replacement frequency is generally a week. The water quality and temperature of the circulating water directly affect the service life of the laser tube. It is recommended to use pure water or distilled water, and the water temperature should be controlled below 35°C. If you do not change the water for a long time, it is easy to form scale, which will block the waterway, so you need to change the water regularly.
Always keep the water flowing. 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℃ water temperature is better); when the water breaks, the tube end will burst due to the heat accumulated in the laser cavity, and may 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 failure or even equipment damage.
2. Maintenance of dust removal system.
If the fan is used for a long time, it will accumulate a lot of dust, which will affect the exhaust and deodorization effect, and it will also produce noise. When you find that the fan suction is insufficient and the exhaust is not smooth, turn off the power first, remove the air inlet and outlet ducts on the fan, remove the dust inside, and then turn the fan backwards, and then move the fan blades inward until So far. Then install the fan. Fan maintenance cycle: about 1 month.
3. Optical system maintenance.
After the machine has been working for a period of time, due to the working environment, a layer of ash will stick to the surface of the lens, which will reduce the reflectivity of the reflective lens and the light transmittance of the lens, and ultimately affect the working power of the laser. At this time, use a cotton ball and ethanol to wipe carefully along the center to the edge of the lens. The lens should be wiped gently to avoid damage to the surface coating; the wiping process should be handled gently to prevent it from falling; the concave surface must be kept facing down when installing the focusing lens. In addition, the number of ultra-high-speed perforations is usually reduced as much as possible, and the use of conventional perforations can extend the life of the focusing lens.
4. Maintenance of transmission system.
When the equipment cuts for a long time, smoke and dust will be generated. Small dust will enter the device through the dust cover and adhere to the rack. Long-term accumulation will increase rack and pinion wear. The rack rail is a relatively precise accessory. Dust is deposited on the surface of the guide rail and linear axis for a long time, which has a great impact on the processing accuracy of the equipment, and will form corrosion points on the surface of the linear axis of the guide rail, shortening the service life of the equipment. Therefore, in order to make the equipment work stably and ensure the processing quality of the product, it is necessary to do a good job of daily maintenance of the guide rail and linear axis, and regularly remove dust. After cleaning the dust, apply grease on the frame and lubricate the guide rails with oil. Each bearing should also be oiled regularly to keep the transmission flexible, process accurate, and prolong the service life of the machine tool.
5. Working environment.
The workshop environment should be kept dry and well ventilated. The ambient temperature is between 4 °C and 33 °C. Prevent the equipment from condensing in summer, and prevent the laser equipment from freezing in winter.
6. Other matters needing attention.
During the operation of the equipment, the operator must observe the working condition of the equipment at any time. In the event of an abnormal situation, all power sources should be cut off immediately, the fault should be rectified or reported to the supervisor in time, and corresponding measures should be taken. Regularly count the usage of the machine, and regularly record the various parts of the laser cutting machine. If it is invalid, it should be replaced in time to prevent it from happening.
