There may be many reasons for the oil leakage of hydraulic CNC turntable. The following are some possible reasons and corresponding treatment methods:

1. Turntable seals are damaged: The turntable seals such as O-rings, sealing rings, etc. may be aged, worn or damaged, resulting in oil leakage. The solution is to replace the damaged seals.

2. Loose or damaged oil pipe connection: The threads at the oil pipe connection may be loose, or the threads may be damaged or the joint may not be well sealed. You need to tighten the loose connection or replace the damaged joint.

3. Oil seal wear or aging: When the turntable rotates, the oil seal will wear or age, causing oil leakage. The worn or aged oil seal needs to be replaced.

4. Poor oil tank sealing: The sealing gasket at the oil tank interface may be loose, aged or damaged, causing oil leakage. The solution is to replace the sealing gasket or adjust the tightening.

5. Pressure regulating valve failure: The pressure regulating valve may be faulty or improperly adjusted, resulting in excessive oil pressure and oil leakage. The pressure regulating valve needs to be checked and adjusted.

If the hydraulic CNC rotary table has an oil leakage problem, you should first stop using the equipment to ensure safety. Then, check and repair it according to the specific situation, replace damaged parts in time, tighten loose connections, and repair or adjust faulty parts. At the same time, regular maintenance and maintenance of the hydraulic system, checking the status of the seals, and timely cleaning and replacing the lubricating oil can effectively prevent the occurrence of hydraulic rotary table oil leakage. If you do not understand the maintenance method or find the operation complicated, it is recommended to consult a professional maintenance personnel for maintenance.
