When there is an oil leakage problem on a CNC vertical lathe, the following measures can be taken to solve it:

1. Check and replace the lubricating oil: First, check the use of lubricating oil in the CNC vertical lathe to ensure that the lubricating oil used meets the manufacturer's recommendations. If there is any problem with the lubricating oil of the CNC vertical lathe, it should be replaced in time. At the same time, regularly check the quantity and quality of lubricating oil to ensure that it is within the normal range.

2. Check the sealing condition of the machine tool: The oil leakage problem of CNC vertical lathe may be caused by the poor sealing condition of the machine tool. Therefore, the sealing parts of the CNC vertical lathe should be carefully checked, especially key parts such as guide rails, to ensure that there is no oil film or other signs of leakage. If sealing problems are found, the seals should be repaired or replaced in time.

3. Check the lubrication system: Failure of the CNC vertical lathe's lubrication system may also cause oil leakage. Therefore, the operation of the CNC vertical lathe's lubrication system should be checked regularly, including checking whether the oil circuit is smooth and whether the oil pipe is damaged, etc. If problems with the lubrication system are found, they should be repaired in time.

4. Replace seals: If the CNC vertical lathe seals are aged or damaged, new seals should be replaced in time to ensure the sealing performance of the machine tool.

5. Clean and tighten screws: Some oil leakage problems on CNC vertical lathes may be caused by loose screws or improper installation of dustproof plates. At this time, the oil on both ends of the guide rail should be cleaned and the screws should be checked to see if they are tight.

When dealing with oil leakage problems, you also need to pay attention to the following points:

1. Operate strictly in accordance with the leakage control standards to ensure that there is no leakage at the external static joint surface of the CNC vertical lathe. Slight leakage is allowed at the dynamic joint surface, but it is not allowed to flow to the ground.

2. Perform regular maintenance and upkeep on the CNC vertical lathe, including cleaning, lubrication and tightening operations to prevent oil leakage.

3. If the oil leakage problem of the CNC vertical lathe is serious or cannot be solved by yourself, you should contact professional maintenance personnel or manufacturers for maintenance in time.

To sum up, solving the oil leakage problem of CNC vertical lathe requires starting from many aspects, including checking and replacing lubricating oil, checking the sealing condition of the machine tool, checking the lubrication system, replacing seals, cleaning and tightening screws, etc. At the same time, it is also necessary to pay attention to operating specifications and regular maintenance to ensure the normal operation of the machine tool and extend its service life.
