Guide rail straight axis, as one of the core parts of the equipment, it is the function of guidance and supporting role To ensure machine has high machining accuracy, to guide rail line has high orientation precision and good movement smoothness of equipment in the process of running, because of the work piece in processing will produce a large number of corrosive dust and smoke, on the basis of these smoke and dust deposit on the surface of guide rail straight axis, a large amount for a long time has a great influence on the equipment of machining precision, and can guide rail straight axis surface erosion point, shorten the service life of the equipment In order to let the machine to normal and stable work, ensure that the quality of processed products, carefully to do the daily maintenance of guide rail straight axis Need to be aware of is the clean of guide rail need to use dry cloth and lubricating oil engraving machine guide is divided into linear guide roller guide, linear guide of cleaning: first turn on the laser head moves to the right (or left), find the linear guide, use dry cloth to wipe until the light clean, add a little oil (sewing machine oil can be used, do not use the oil), the laser head slowly pushed around a few times, can let the oil evenly distributed to roller guide rail cleaning: move beam inside, open the machine on both sides of the end cover, find the roller guide rail, with dry cloth on both sides of the guide rail and the roller contact place to wipe clean, and moving beam, the rest place clean
