一前言 液体静压技术在机床中多应用于支承部件,包括静压轴承、静压导轨和静压丝杠(简称“三静技术”)。液体静压支承的主要特点是:依靠供油系统供给压力油,通过节流系统,将进入支承油腔中的压力调节到与外界负载相当。因此,在各种相对运动速度下均可使支承处于完全液体摩擦状 A foreword Hydrostatic technology in the machine tool and more used in supporting components, including hydrostatic bearings, hydrostatic rails and hydrostatic screw (referred to as “three static technology”). The main features of hydrostatic support are: rely on the supply system to supply pressure oil, through the throttle system, the pressure into the support oil chamber to adjust to the load and external load. As a result, the bearing can be completely liquid friction-like at various relative speeds of motion
