When using the laser machine, we should pay attention to the maintenance and maintenance of the machine.<br/>1: the replacement of water and the cleaning of the water tank<br/>Suggestion: clean the water tank and replace the circulating water once a week.<br/>Note: the machine must ensure that the laser tube is full of circulating water before working.<br/>The water quality and temperature of the circulating water directly affect the service life of the laser tube. It is suggested that pure water should be used and the water temperature is controlled below 35. If more than 35 degrees centigrade, the circulating water should be replaced or the water is added to the water to reduce the water temperature. (recommend the user to choose the cooler, or use two water tanks). Water pipe, let the water in the laser tube automatically flow into the water tank, open the water tank, remove the water pump, remove the dirt on the pump. Clean the water tank, replace the circulating water, restore the water pump back to the water tank, insert the water pump connecting the water pump into the intake, and arrange the joints. The water pump alone is electrified and runs for 2-3 minutes (the laser tube is full of circulating water).<br/>Two, the cleaning of the fan<br/>The long time use of the wind machine will make the fan accumulate a lot of solid dust, make the fan produce a lot of noise, and it is not conducive to the exhaust and odor removal. When the suction force of the fan is insufficient, the power is closed first, the inlet pipe and the outlet pipe on the fan are unloaded, the dust of the inner surface is removed, and then the fan is inverted and pulls inside. Clean the blades until clean.<br/>Three: the cleaning of the lens<br/>(it is recommended to clean daily before work, and the equipment must be shut down.<br/>There are 3 mirrors and 1 focus mirrors on the engraving machine (No. 1 reflector is located at the outlet of the laser tube, that is, the upper left corner of the machine, the 2 mirror is located at the left end of the beam, the 3 mirror is located at the top of the fixed part of the laser head, and the focus mirror is located in the cylinder of the lower part of the laser head). The laser is reflected through these lenses, After focusing on the laser hair. The lens is easily contaminated with dust or other pollutants, causing laser loss or lens damage. Do not take off when cleaning the 1 and 2 lenses. Only the cleaning paper dipped in the cleaning liquid is carefully swirled along the center of the lens to the edge of the lens and the focus mirror needs to be removed from the mirror frame and the same is needed from the mirror frame. Wipe the sample method and wipe it back.<br/>Note: 1. lenses should be gently wiped, not to damage the surface coating; 2. the wiping process should be light and light to prevent falling; 3. when installing the focus mirror, please keep the concave down.<br/>Four, the cleaning of the guide rail<br/>(it is recommended to be cleaned once every half month and shut down).<br/>As one of the core components of the equipment, the linear axis is one of the core components of the equipment, its function is to play the role of guiding and supporting. In order to ensure the machine has high machining precision, the guide rail is required, the straight line has high guidance precision and good motion smoothness. In the process of operation, the machined parts will produce a lot of corrosiveness in the process of processing. Dust and smoke, which have long been deposited on the guide rail, the linear axis surface, have a great influence on the machining precision of the equipment, and will form the corrosion point on the linear axis surface of the guide rail and shorten the service life of the equipment. In order to make the machine work well and ensure the quality of the product, we should do a good job of the guide rail and the linear axis. Maintain.<br/>Attention: clean guide rail, please prepare dry cotton cloth, lubricating oil.<br/>Five, screw, couplet fastening<br/>In the movement system, after a period of work, the screw of the motion connection, the coupling will become loose, which will affect the smoothness of the mechanical motion. So, in the machine operation, it is necessary to observe whether the transmission parts are abnormal or abnormal, and the problem should be sturdy and maintained in time. At the same time, the machine should be sturdled by tools one by one for a period of time. Silk. The first firm should be about a month after the equipment is used.<br/>Six, the optical path inspection laser engraving machineundefineds optical system is completed by the reflection of the mirror and focusing of the focus mirror. In the optical path, the focusing mirror does not have the offset problem, but the three mirrors are fixed by the mechanical part and the offset is more likely. Although the offset is not usually taken, it is suggested that the user work each time. Be sure to check whether the light path is normal.
