Perpendicular guide rail of two rectangle chamber static pressure supporting lubricating pad

The utility model provides a perpendicular guide rail of two rectangle chamber static pressure supporting lubricating pad, this lubricating pad structure of mainly includes resistive oil edges, oil pocket, oil inlet. During the lubricated and supporting of heavy vertical numerical control lathe intermediate slide is applied to to static pressure guide rail lubricated perpendicularly, good and baddirect influence to the surface quality of work piece and the machining precision of whole lathe of its performance. In the course of working, because stroke and cutting force that the knife rest ramstretches out from the slide are all bigger, the clearance oil film probably because bearing capacity and stiffness is not enough by the conquassation, arouses machining error, reduces the machining precision. In order to solve this difficult problem, the utility model provides a becoming present two rectangle chambeies hydrostatic bearing rectangle lubricating pad with original single rectangle chamber hydrostatic bearing
