The four main points affect the spindle system accuracy
Clicks:7598 Date:8-12
The four main points affect the spindle system accuracy
1. The radial runout of the bearing ring will cause radial runout of the spindle axis of the main shaft system so that the errors can be reflected on the machined surface.
2, the bearing rolling body diameter inconsistency and shape error will cause the main shaft to produce regular error.
3, the channel on the end side of the pendulum will cause axial spindle, spindle axial dynamic precision grinder, especially bearing grinder effect is especially significant if the process of adopting ditch groove grinding way, will make the scrap rate is greatly improved, the noise will also increase.
4, the working surface of the bearing installation dimension and shape error will make the bearing raceway corresponding deformation, the inner and outer rings of the bearing tilt in all directions so that the bearing stiffness is not uniform, which will reduce the rotation accuracy of the spindle system.
The clearance nut, spacer sleeve and washer end face need to be processed by grinding, and the verticality of the axis of rotation of the shafting must correspond with the accuracy of the installed bearings. Otherwise, the working accuracy of the bearing will be reduced.
