The accuracy of CNC lathe spindle bearing system is mainly affected by the following factors: 1) The axial vibration of the section of the bearing throw ring will cause axial vibration of the spindle center line, and the difference can be seen in the outer ring of the bearing. 2) Inconsistent diameters and morphological deviations of the bearing reversing body may cause periodic deviations in the main shaft. 3) The side swing of the cross section to the inner hole will cause the radial shaking of the main shaft, and the radial shaking of the main shaft is particularly harmful to the precision grinder, especially the bearing CNC grinder. The pass rate is greatly improved, and the noise is also greatly improved. 4) The deviation of the specification and position tolerance of the CNC lathe spindle bearing installation table will cause corresponding deformation of the bearing raceway, skew the inner and outer rings of the bearing, and cause the bearing to have inconsistent bending stiffness in each direction, which will reduce the rotation accuracy of the spindle system. . The inner hole of the nut, spacer, and seal ring for adjusting the spacing must be finely ground and processed, and the flatness of the shaft rotation centerline should correspond to the accuracy of the installed bearing, otherwise the accuracy of the bearing in operation will be reduced. 37 years of experience in the production of CNC lathe spindle bearings, tailor-made solutions for customers according to various scenarios, providing matching solutions, covering an area of ​​25 acres, the company has passed the ISO9001 quality management system certification, and obtained the provincial high-tech enterprise certification.
