Abstract

Due to higher requirements for accuracy appearing in machining, hydrostatic bearings have begun to be used in the motor spindles of high precision machine tools. These types of bearings have much better static stiffness and damping ratio, than rolling element bearings, but their rotational speed capability is strictly limited. This paper deals with the examination of hydrostatic bearings applications at high-speed machine tool spindles.
