Stay Machining of mechanical parts In ， It is necessary to ensure the sensitivity of rail holding pressing plate at all times ， This is the basic requirement of hydraulic system ， If there is a blockage in the hydraulic line or the solenoid valve is not sensitive ， Make the pressing plate weak or lag ， The consequences are very serious 。

　　 For example ， You pressed. X Axis enable button ， Select the direction to start running now ， At this time, one pressing plate after another has not been completely released ， Will make Y Shaft shaking and even crawling ， Seriously affect the service life of machine tools 。 Conversely ， For example, hardware processing C60 Positioning precision boring ， And hydraulic pressure can't push the pressing plate to death Will make Machine tool drifts ， Boring In Heart position may change 。

　　 Stay Machining of mechanical parts In ， About X Crawling of shaft guide rail ， There are two other unique reasons ， It is the problem between oil-water mixing and start-up acceleration performance 。 Good. Machining plant Experience ， This phenomenon Stay Y Shaft guide and V The movement of the shaft guide rail is not obvious 。
