This　paper　provides　a　comprehensive　exploration　of　the　operational　mechanism　of　an　internal　feedback　hydrostatic　turntable.　It　employs　a　self-compensating　gap　restrictor　mechanism,　resulting　in　heightened　load　capacity　and　stiffness.　In　this　paper,　the　concept　of　internal　flow　is　innovatively　introduced.　Subsequently,　the　Reynolds　equation　is　solved　using　the　finite　difference　method.　This　methodology　offers　a　more　precise　and　efficient　assessment　of　the　load-bearing　performance　of　the　oil　pad　within　the　turntable.　Then　this　paper　further　investigates　the　influence　of　the　internal　flow　coefficient　and　pressure　ratio　on　oil　pad　performance,　encompassing　aspects　like　load　capacity,　stiffness,　and　flow　rate.　Ultimately,　optimal　parameters　are　selected　to　improve　the　structure　of　the　gap　restrictor,　considering　various　operational　scenarios.　In　conclusion,　the　method　adopted　in　this　study　not　only　improves　the　calculation　accuracy　and　efficiency　but　also　improves　the　structure　and　performance　of　the　oil　pad.　The　hydrostatic　turntable　is　a　critical　component　of　numerous　computerized　numerical　control　machine　tools.　This　paper　provides　a　more　comprehensive　exploration　of　the　operational　mechanism　of　an　internal　feedback　hydrostatic　turntable.　In　addition,　this　study　proposes　a　more　accurate　and　efficient　method　to　analyze　the　performance　of　the　oil　pad　and　optimize　its　structure.image
