The precision of linear guides is not the same. For example, the machine tool industry requires high precision for the workpieces processed, so precision linear guides above H level are generally used, while the automation industry generally only needs to play a transmission role, and the accuracy requirements Not high, generally N-level is mostly used.
Linear guide rail selection firstly depends on the weight of the workbench and the size of the workbench, in order to calculate the approximate model and length of the rail to be used. With the approximate model and length, the next step is to confirm the installation size of the slider. The slider has flange type and square type, and these two types are divided into ordinary and extended. If the load is large, it is recommended to use the extended slider.
As one of the core components of the equipment, the linear guide rail functions as a guide and support. In order to ensure the high processing accuracy of the machine, the guide rails and straight lines are required to have high guiding accuracy and good movement stability. During the operation of the equipment, due to the large amount of corrosive dust and smoke generated during the processing of the processed parts, these smoke and dust will be deposited on the surface of the guide rail and linear shaft for a long time, which has a great impact on the processing accuracy of the equipment, and will Corrosion points are formed on the surface of the linear axis of the guide rail, which shortens the service life of the equipment.
In order to make the machine work normally and stably and ensure the processing quality of the products, the daily maintenance of the guide rail and linear axis must be done carefully. Please prepare dry cotton cloth and lubricating oil to clean the guide rail. First move the laser head to the right (or left), find the linear guide, wipe it with a dry cotton cloth until it is bright and dust-free, add a little lubricant, and slowly push the laser head to the left and right several times to distribute the lubricant evenly. can.
Move the beam to the inside, open the end covers on both sides of the machine, find the guide rails, wipe clean the areas where the guide rails on both sides are in contact with the rollers with a dry cotton cloth, and then move the beam to clean the remaining areas. Normal linear guides need to be adjusted before leaving the factory. The surface is wiped with anti-rust oil, but after a period of use, it will still show serious rust.
Therefore, after the linear guide is used, it is necessary to apply anti-rust oil on its surface again. It should be placed in a warehouse at room temperature. It cannot be mixed with corrosive objects, nor can the linear guide that is not used temporarily , Stored directly on the floor of the warehouse, because the ground will accelerate the evaporation of rust-preventing oil, so this requires everyone to pay more attention when using it.
