Laser Machine Maintenance
The main components of the laser cutting machine are mainly divided into: circuit system, transmission system, cooling system, light source system, and dust removal system. The daily key 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 quality of the beam), and the transmission system (the focus needs to be paid attention to to ensure normal operation)
How to extend the service life of laser cutting machine?
First of all, when the work needs to use the cutting machine, we must push the beam before starting the machine, try to move it back and forth, and there is no abnormal noise when moving left and right, and then the power can be turned on. After completing the work of the day, clean up the materials and waste residues produced in the machine that day. This protects the machine's motion system from being damaged by foreign objects. Clean up its moving parts to keep the machine in good working condition. The specific methods are as follows:
1. Maintenance of cooling system
The water inside the water cooler must be replaced regularly, and the general replacement frequency is one week.
Make sure that the laser tube is filled with circulating water before the machine works.
The quality and temperature of the circulating water directly affect the service life of the laser tube.
It is recommended to use pure water ,deionized water or distilled water, and control the water temperature below 35°C.
If the water is not changed for a long time, it is easy to form scale, which will block the waterway, so be sure to change the water regularly.
2. Maintenance of dust removal system
After the fan is used for a long time, a lot of dust will accumulate inside, which will affect the effect of exhaust and deodorization, and will also generate noise.
When it is found that the suction power of the fan is insufficient and the smoke exhaust is not smooth, the fan should be cleaned. First turn off the power, remove the air inlet and outlet ducts on the fan, remove the dust inside, then turn the fan upside down, move the fan blades inside until it is clean, and then install the fan.
Fan maintenance cycle: once a month.
3. Cleaning of the optical path system maintenance lens
After the machine works for a period of time, the surface of the lens will be covered with a layer of ash due to the working environment, thereby reducing the reflectivity of the reflective lens and the transmittance of the lens, and finally affecting the working power of the laser.
At this time, use absorbent cotton dipped in ethanol to carefully rotate along the center of the lens to the edge.
4. Transmission system maintenance
During the long-term cutting process of the equipment, smoke and dust will be generated, and the fine dust will enter the equipment through the dust cover, and thus adhere to the rail rack, and the long-term accumulation will increase the wear of the rail rack. Rack guides are relatively precise accessories, and a large amount of dust is deposited on the surfaces of the guides and linear shafts for a long time, which has a great impact on the machining accuracy of the equipment, and will form corrosion spots on the surface of the linear shafts of the guides, 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 in the daily maintenance of the guide rails and linear axes, and do regular dust removal and cleaning. After cleaning the dust, grease the rack and lubricate the rail with lubricating oil. Each bearing should also be filled with oil regularly, so as to maintain flexible driving, accurate processing and prolong the service life of the machine tool.
