Linear rails, also known as rails, rails, linear rails, linear rails, for linear reciprocating motion occasions, and can take a certain torque, can be in the case of high load to achieve high-precision linear motion. In the mainland, said linear guide, Taiwan is generally called linear guide, linear slide.
　　Straight rails are precision parts, and therefore require considerable caution when used, even with high-performance linear guides, which can not be expected to achieve the desired performance and easy to damage the linear guide if used improperly. Therefore, the use of linear guide should pay attention to the following:
　　1. Keep the environment clean: keep the linear guide and its surrounding environment clean even the invisible tiny dust into the guide rail, will increase the rail wear, vibration and noise.
　　2. To prevent corrosion: directly with the hand to take with Mao linear guide, to fully wash away the sweat on hand, and coated with high-quality mineral oil and then operate in the rainy season and summer, especially to pay attention to rust.
　　3. Installation tools to be suitable: Use a suitable linear guide rail, accurate installation tools try to use special tools, be careful to avoid the use of cloth and staple fiber and the like.

　　4. Installation should be careful: linear guide in the use of the installation should be careful, not allowed to stamping, do not allow the hammer directly hit the rail, does not allow the transfer of pressure through the rolling body.
　　When using a linear guide, require a considerable degree of caution, if used improperly, can not achieve the desired performance results, but also easy to damage the guide.
　　Use linear guide to pay attention to lubrication maintenance, from time to time to add or replace the filling of fat way. For a number of rails need to lubricate the machinery, but also the use of pipelines connected to the lubrication of the centralized supply of fat way. Frequent lubrication can greatly improve the service life of the rail.
　　The function of the linear guide is guided and supported. In order to ensure that the machine has a higher processing accuracy, requiring its rails, straight line with a high degree of guidance accuracy and good sport stability. During the operation of the equipment, due to the processing of the workpiece will produce a lot of corrosive dust and smoke, the base of these fumes and dust long-term deposition in a large number of rails, linear shaft surface, the equipment processing accuracy has a great impact, and will The formation of corrosion points on the surface of the linear axis of the guide rails, shortening the service life of the equipment. In order to make the machine normal and stable work to ensure that the quality of processing products, to do a good job of rails, linear shaft routine maintenance.
