The accuracy of the CNC lathe spindle bearing system is mainly affected by the following factors: 1) The axial vibration of the section of the bearing throwing ring will cause the axial vibration of the spindle centerline, and the difference can be seen in the outer ring of the bearing. 2) The inconsistency of the diameter and shape deviation of the bearing turning body may cause the main shaft to cause periodic deviation. 3) The side swing of the inner hole of the section will cause the radial shaking of the main shaft. The radial shaking of the main shaft is particularly harmful to precision grinding machines, especially bearing CNC grinding machines. The pass rate is greatly improved, and the noise will be greatly improved. 4) The specification and position tolerance deviation of the CNC lathe spindle bearing installation table surface will cause the corresponding deformation of the bearing raceway, skew the inner and outer rings of the bearing, and cause the bending stiffness of the bearing to be inconsistent in each direction, which will reduce the rotation accuracy of the spindle system . The inner holes of the nuts, spacers, and sealing rings for adjusting the distance need to be ground and processed, and the flatness with the axis of rotation of the shaft should correspond to the accuracy of the installed bearings, otherwise the working accuracy of the bearings will be reduced. 37 years of experience in the production of CNC lathe spindle bearings, tailor-made solutions for customers according to various scenarios, provide matching solutions, covers an area of ​​25 acres, the company has passed the ISO9001 quality management system certification, and obtained the provincial high-tech enterprise certification. The company was listed on the New Third Board in 2016, and the annual report is disclosed twice a year. The operation is standardized and the development prospect is good. It can provide you with continuous and stable supply capacity and perfect after-sales service. Only when the torque is accurate can the rotation be stable!
