In　milling-grinding　machines,　rotary　tables　with　sub-micron　accuracy　are　becoming　more　necessary.　Usually,　the　radial　error　of　rolling　bearing　is　difficult　to　achieve　the　sub-micron　accuracy.　For　this　reason,　the　hydrostatic　bearing　with　high　rotation　accuracy　and　large　supporting　stiffness　were　used　in　rotary　table　in　milling-grinding　machine.　The　present　work　describe　the　design,　development　and　testing　of　precision　hydrostatic　rotary　table　consisting　of　a　journal　bearing　and　a　double-thrust　bearing.　For　precision　design　of　components,　radial　and　axial　runout　error　models　were　established.　Performed　tests　indicate　that　the　preliminary　measured　accuracy　highlight　the　proposed　hydrostatic　rotary　table＇s　potential　for　millinggrinding　machine.
