The price of laser cutting machines is not low, ranging from hundreds of thousands to millions. Therefore, prolonging the service life of the laser cutting machine as much as possible can better save production costs and win greater benefits. It can be seen that the daily maintenance and maintenance of the laser cutting machine are very important. The following is mainly explained from the following aspects:
1. Replacement of circulating water and cleaning of the water tank: 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. Therefore, it is necessary to regularly replace the circulating water and clean the water tank. This is best done once a week.
2. Fan cleaning: The long-term use of the fan in the machine will cause a lot of solid dust to accumulate in the fan, making the fan generate a lot of noise, and is not conducive to exhaust and deodorization. When the suction of the fan is insufficient and the smoke exhaust is not smooth, it is necessary to clean the fan.
3. Cleaning of the lens: There will be some mirrors and focusing mirrors on the machine. The laser is reflected and focused by these mirrors and emitted from the laser head. The lens is easily stained with dust or other contaminants, resulting in loss of laser light or damage to the lens. So clean the lenses every day. When cleaning, pay attention to 1. The lens should be wiped gently to avoid damaging the surface coating; 2. The wiping process should be handled with care to prevent it from falling; 3. Please keep the concave side down when installing the focusing lens.
Fourth, guide rail cleaning: guide rail and linear shaft are one of the core components of the equipment, and their function is to guide and support. In order to ensure the high machining accuracy of the machine, its guide rails and straight lines are required to have high guiding accuracy and good motion stability. During the operation of the equipment, a large amount of corrosive dust and smoke will be generated during the processing of the workpiece, and this smoke and dust will be 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 Corrosion spots are formed on the surface of the linear shaft of the guide rail, which shortens the service life of the equipment. Therefore, clean the machine guide rails every two weeks. Turn off the machine before cleaning.
5. Tightening of screws and couplings: After the motion system has been working for a period of time, the screws and couplings at the motion joints will become loose, which will affect the stability of the mechanical movement. There is no abnormal sound or abnormal phenomenon, and the problem should be strengthened and maintained in time. At the same time, the machine should tighten the screws one by one with a tool over a period of time. The first firming should be about a month after the device is used.
