As one of the core parts of the equipment, the linear axis in the linear guide rail plays a guiding and supporting role. In order to make the machine have a higher degree of processing, the guide rail and straight line are required to have higher guidance and good motion stability.

直线导轨在运行过程中，在加工中会产生大量的腐蚀性粉尘和渣滓，这些渣滓和粉尘就会沉积于导轨、直线轴表面，长期以往的积累，对设备的加工会产生很大的影响，并且会在导轨直线轴表面形成蚀点，这样就会缩短设备使用寿命。

During the operation of linear guide rail, a large amount of corrosive dust and dross will be produced in the process of processing. These dross and dust will deposit on the surface of guide rail and linear axis. The long-term accumulation will have a great impact on the processing of equipment, and will form corrosion spots on the surface of linear axis of guide rail, which will shorten the service life of equipment.

清洁前要准备润滑油、干棉布。把横梁移动到内侧，打开机器两侧端盖，找到导轨，用干棉布把两侧导轨与滚轮接触的地方擦拭干净，再移动横梁，把剩余地方清洁干净把激光头移动到右侧(或左侧)，找到直线导轨，用干棉布擦拭直到光亮无尘，再加上少许润滑油(切勿使用机油)，将激光头左右慢慢推动几次，让润滑油均匀分布即可。

Prepare lubricating oil and dry cotton cloth before cleaning. Move the crossbeam to the inside, open the end covers on both sides of the machine, find the guide rail, wipe the contact area between the guide rail and the roller with dry cotton cloth, then move the crossbeam to clean the rest, move the laser head to the right (or left), find the linear guide rail, wipe it with dry cotton cloth until it is bright and dust-free, and add a little lubricating oil (do not use engine oil), Push the laser head left and right slowly for several times to evenly distribute the lubricating oil.
