The subject of investigation is dynamic performance of radial hydrostatic bearings (HSB) of main spindle of modern high-production metal-cutting equipment. The possibilities for vibrostability improvement are considered by the radial skew of spindle axis in HSB. The developed method description of the optimal parameters of correcting RC-circuits definition is given. The transients and response functions are computed and analyzed for different operating modes of HSB.
