静压导轨具有工作寿命长、摩擦系数低、速度和载荷变化对油膜刚度影响小，工作性能稳定等优点。但在实际应用中高速静压导轨受到了很大限制，由于转速的提高造成系统发热量和油温升高，导致导轨及工作台热变形严重，机床工作稳定性不好等问题。针对以上问题，对一种高速回转工作台所用静压导轨进行了结构设计与相应计算。
靜壓導軌具有工作壽命長、摩抆繫數低、速度和載荷變化對油膜剛度影響小，工作性能穩定等優點。但在實際應用中高速靜壓導軌受到瞭很大限製，由于轉速的提高造成繫統髮熱量和油溫升高，導緻導軌及工作檯熱變形嚴重，機床工作穩定性不好等問題。針對以上問題，對一種高速迴轉工作檯所用靜壓導軌進行瞭結構設計與相應計算。

Hydrostatic guide-way has the characteristics of low coefficient of friction, speed and loading variety to the oil film rigidity influence small, the working ability stabilized. But at application in high-speed hydrostatic guide-way is very greatly limited and result in the system has fever quantity and oil temperature to heat up and lead the guide-way and table thermal deformation because of the rotary speed up, and the machine tool works stability not very well. Therefore, the calculation and structure design of hydrostatic floating guideway are carried out in this paper.
