In the case of high speed rotating spindle, a multiDOF hydraulic load experimental station was designed to measure the spindle rotation accuracy and the dynamic stiffness under load conditions, applying the theory that hydraulic cylinder had a large thrust. Since the experimental station had multiDOF, it could be used to multidirectional load，its hydraulic pump and relief valve also could be used to change the loading force easily. The experimental station can be widely used in performance test of lathes and other machine tools.
