Based on computational fluid dynamics, friction lubrication theory and hydrostatic technology, large size hydrostatic Guide-way of heavy vertical CNC lathes，which are widely used, was taken as research object. The control equation of hydrostatic guide-way’s interstitial fluid was established. By finite volume method, lubricating oil properties, boundary conditions such as constant flow inlet, outlet pressure, and wall were set. The velocity distribution of hydrostatic thrust bearing’s interstitial fluid was obtained through iterative computations. And influence rules of cavity depth on interstitial oil-film of large size hydrostatic Guide-way’s was discussed. The results reflect hydrostatic bearing’s internal fluid flow state .and provide theoretical basis for the design of practical engineering hydrostatic bearing.
