莫斯科机床工具研究所同莫斯科机器制造厂联合研制了一种分开式静压轴承装置,用以支撑主轴并进行主轴内锥孔的磨削。截至1984年初总共加工主轴零件90000余根,从未发现主轴和轴承有擦伤的痕迹。把主轴安放在这种静压轴承内加工,尽管被加工主轴与轴承之间存在着较大间隙,由于主轴与轴承之间形成的油膜消除了余隙,主轴的位置精度和旋转精度可达到1～2级。除此之外,由于主轴与轴承之间有一层油膜,它的粘度和弹性模量较大,大大吸收了震动能量,轴承工作稳定性高,改善了主轴的加工质量。磨削时不用冷却液,减少了技术上的困难,防止了油从轴承中溢出,外界磨料粉尘也不易进入到轴承内,
Moscow Machine Tool Research Institute and the Moscow machine factory jointly developed a split hydrostatic bearing device to support the spindle and spindle taper hole grinding. As of the beginning of 1984, a total of more than 90,000 spindle parts were machined, and no scratches on the spindle and bearings were found. The spindle placed in this hydrostatic bearing processing, despite being processed spindle and bearing the existence of a large gap between the spindle and the bearing formed between the oil film to eliminate the clearance, the spindle position accuracy and rotation accuracy of up to 1 ~ 2 levels. In addition, due to the oil film between the spindle and the bearing, its viscosity and elastic modulus are large, which greatly absorb the vibration energy, and the bearing has high work stability and improves the machining quality of the spindle. Grinding without coolant, reducing the technical difficulties, to prevent the oil from overflow bearings, the outer abrasive dust is not easy to enter the bearings,
