This lecture mainly introduces the construction points of the spindle functional components composed of dynamic and static pressure hybrid bearings and the typical structure for the inner and outer grinding components. I. Several problems of the overall design of the spindle shaft system A good spindle function component, in addition to the selection of advanced bearings, the overall design of the shafting system should consider the following points: 1. System stiffness of the shaft The system stiffness of the spindle means that the spindle is Resistance to deformation under external forces (grinding force, gravity and transmission force)
