If oil leakage occurs in a CNC vertical lathe, timely measures need to be taken to prevent the normal operation of the machine tool from being affected. Here are the general steps for dealing with an oil leak:

1. Determine the location of oil leakage: First, you need to carefully check all parts of the CNC vertical lathe to determine the specific location of the oil leakage. Possible oil leakage locations include lubrication systems, hydraulic systems, seals, etc.

2. Check the seals: If the oil leakage is caused by damaged seals, you need to check the corresponding seals, including shaft seals, sealing rings, etc. If the seal is found to be damaged or aged, it should be replaced in time.

3. Check the lubrication system: If the oil leakage of the CNC vertical lathe is caused by a failure of the lubrication system, you need to check the oil pipes, oil seals, oil pumps and other components of the lubrication system to ensure the normal operation of the lubrication system. If there is oil leakage, relevant parts of the lubrication system need to be repaired or replaced in time.

4. Tighten bolts: Oil leakage from CNC vertical lathes is sometimes caused by loose bolts or loose sealing on the machine tool. You can check and tighten the corresponding bolts appropriately to ensure that each component of the machine tool is in good sealing condition.

5. Clean the oil leakage part: CNC vertical lathe cleans the oil around the oil leakage part to facilitate subsequent observation and processing. At the same time, it is easier to detect the specific location of oil leakage after cleaning.

6. Repair or replace parts: CNC vertical lathe will repair or replace oil leaking parts according to the actual situation. If the CNC vertical lathe needs to replace parts, original parts or equivalent quality substitutes that meet the specifications and quality requirements should be selected.

7. Regular inspection: After the oil leakage problem is solved, the CNC vertical lathe should regularly check the lubrication system, seals and other components to ensure the normal operation of the machine tool, and discover and deal with potential problems in a timely manner to prevent oil leakage from happening again.

If the cause of the oil leak cannot be determined or cannot be solved by yourself, it is recommended to contact professional maintenance personnel or manufacturer technical support for further inspection and repair.
