As the backbone of modern manufacturing, CNC lathes’ performance and accuracy directly affect an enterprise’s production efficiency and product quality. However, as the service life increases, CNC lathes will inevitably experience various failures and require major repairs.

1. Spindle bearing failure Spindle bearing is one of the key components of CNC lathe, and its performance directly affects the rotation accuracy and stability of the lathe. During the overhaul process, if the spindle bearing is found to have abnormal wear, looseness or abnormal noise, it may be a spindle bearing failure. At this time, the bearings need to be replaced or adjusted to ensure the accuracy and stability of the lathe.

2. Transmission system failure The transmission system is an important part of the CNC lathe. Its failure usually manifests itself as looseness, breakage or gear wear of the transmission belt. During the overhaul process, if abnormal sounds, vibrations or heat are found in the transmission system, it may be a transmission system failure. At this time, the transmission system needs to be inspected and repaired to ensure the normal operation of the lathe.

3. Electrical system failure The electrical system is the control core during the CNC lathe overhaul process. If abnormal sound, heat or sparks are found in the electrical system, the failure usually manifests as circuit board damage, poor contact or component aging. Now, it may be an electrical system failure. At this time, the electrical system needs to be inspected and repaired to ensure the normal control and action of the lathe.

4. Hydraulic system failure The hydraulic system is one of the important auxiliary devices of CNC lathes. Its failure usually manifests itself as hydraulic oil leakage, hydraulic pump noise or excessive oil temperature. During the overhaul process, if abnormal sounds, vibrations or heat are found in the hydraulic system, it may be a hydraulic system failure. At this time, the hydraulic system needs to be inspected and repaired to ensure the normal auxiliary action of the lathe.
