1. Filling the lubricating oil into the linear guideAs we know, the smoke and dust generated by engraving and cutting will cause damage to the guide rail after a period of use, so we need to do a good job in the daily maintenance of the guide rail. Please turn off the laser engraving machine, cut off the power supply, clean the guide rail with a clean wool edge, then drop the lubricating oil on the guide rail and try to move the slide bar to make sure the oil enters the slide bar. After refueling, let the slide Rod move on the guide rail. Now we need to install the guide rail first. Please don\'t fix the guide rail first, install the screw in the correct position, and keep the sliding Ray at an even level. Then fix the belt and slide bar, install the lens, and then adjust the destination of xlight. 2. Cleaning mirrors and focus mirrors after using laser engraving and laser cutting machines for a period of time, smoke and dust will attach to the surface of mirrors and mirrors, which will affect the depth of engraving and cutting, engraving and cutting accuracy will also be affected. We need to clean three reflector and one focus mirror every week with pure alcohol. 3. Oil- The filling of the BearingA laser engraving machine is equipped with a large number of bearings, in order to maintain a good carving and cutting effect, part of the bearings need to be filled with oil regularly (except the oil- Fixed Bearing). Wipe the surface dust on the bearing with a clean mull, take a syringe, suck in some oil, then fill the bearing with a needle and move the bearing at the same time. 4. The adjustment of the synchronous belt has some synchronous belts on a laser engraving machine. If the synchronous belt is too loose, it will lead to a double image of the lettering. If the synchronous belt is too tight, it will cause the synchronous belt to wear. After a period of use, please adjust the tightening screw of the timing belt, adjust the timing belt until its tightness is appropriate, when there is no double image of the engraved text, and the noise of the laser engraving and laser cutting machine is very low, this is enough, or you can consult our technicians. 5. The maintenance of the laser tube of the laser tubithe laser engraving machine uses circulating water as a cooling system, and some burrs will appear inside the laser tube over time. We can put a little vinegar in the circulating water, and the vinegar will melt the fur. After that, we will use some clean water to clean the tube. Therefore, the laser tube will be in the best working condition and its life will be longer.
