introduction：abbaLinear guide maintenance abbaHigh positioning accuracy when using linear guide rails as linear guidance，Because the friction mode of linear guide rail is rolling friction，Not only is the friction coefficient reduced to slide-guided1/50，The difference between dynamic friction and static friction force also becomes very small。So when the bed is running，There will be no slippage，attainabilityμmLevel of positioning accuracy。Traditional slide guidance with less wear can maintain accuracy for a long time，It is inevitable that the platform movement precision will be poor due to the greasy countercurrent action，And due to insufficient lubrication during exercise，It causes the wear of the contact surface of the running track，Seriously affect accuracy。The wear of the rolling guide is very small，Therefore, the machine can maintain accuracy for a long time。 Linear guide cleaning and maintenance： rail、The linear shaft is one of the core components of the equipment，Its function is to guide and support。In order to e
