The　carrying　capacity　of　hydrostatic　turntable　was　influenced　by　the　profile　error.　A　direct　method　to　solve　the　static　equilibrium　was　proposed　to　obtain　the　axial　motion　error　and　the　angular　motion　error　components　of　the　turntable　based　on　the　structural　characteristic　of　the　heavy　duty　CNC　hydrostatic　turntable　and　under　the　assumption　that　the　turntable　is　a　rigid　body　and　has　no　deformation.　Thus　the　working　state　was　achieved.　The　guideway　of　a　hydrostatic　turntable　was　analyzed　with　the　method,　and　the　influence　of　the　profile　error　component　on　the　variation　of　the　axial　motion　error　and　angular　motion　error　components　with　wavelength　was　obtained.　In　order　to　gain　a　deeper　understanding　of　the　turntable　guideway,　this　paper　investigates　the　relationship　between　the　supporting　forces　of　a　single　hydrostatic　pad　with　the　wavelength.　The　results　show　that　the　profile　error　of　hydrostatic　turntable　has　a　great　influence　on　bearing　characteristics,　and　the　axial　motion　error　and　the　supporting　force　show　similar　performance　with　the　profile　error　and　increase　with　the　increasing　of　the　profile　error　amplitude.
