Machining　error　in　machining　processes　arises　due　to　several　factors.　The　tilt　angle　of　the　spindle　of　the　machine　tool　is　one　of　the　important　factors　that　directly　affect　the　shape　error,　surface　quality,　and　roughness　of　the　machined　part.　In　order　to　better　analyze　the　effect　of　microscale　effects　on　the　tilt　angle　of　a　hydrostatic　spindle,　a　fluid　control　model　at　the　microscale　is　introduced　into　the　traditional　Reynolds　equation.　The　static　performance　characteristics　of　hydrostatic　bearings　with　four　and　eight　pads　under　the　influence　of　velocity　slip　are　obtained.　The　results　show　that　the　existence　of　velocity　slip　improves　the　stiffness　of　the　bearing.　However,　the　influence　of　velocity　slip　on　the　tilt　angle　is　obvious,　and　the　tilt　angle　decreases　as　the　increase　of　velocity　slip.　The　experimental　results　verify　the　existence　of　velocity　slip　at　the　microscale　indirectly　and　provide　a　theoretical　basis　for　the　study　of　the　performance　of　liquid　hydrostatic　bearings　at　the　microscale.
