It is very important to perform maintenance on CNC vertical lathes during the holidays to ensure that the CNC vertical lathes are not damaged during the holidays and can run smoothly when work resumes. Here are some suggestions for maintenance:

1. Clean the machine tool: Before the holiday, thoroughly clean the surface and interior of the CNC vertical lathe. Remove dust and dirt from the surface, especially residues of CNC vertical lathe lubricating oil and coolant. Ensure that the exterior and interior of CNC vertical lathes are clean to prevent dirt from affecting parts and lubrication systems.

2. Lubrication system: Ensure the normal operation of the CNC vertical lathe lubrication system and replace the lubricating oil according to the manufacturer's recommendations. During the holidays, check whether the oil in the lubrication system is sufficient and add or replace it if necessary.

3. Protect the guide rails: Inspect and protect the guide rails of CNC vertical lathes. Clean the rail surface and apply an appropriate amount of rail oil or grease to prevent rust and wear.

4. Check the electrical system: Check the electrical system of the CNC vertical lathe to ensure that the cables of the CNC vertical lathe are well connected and the switches and buttons are normal. Check the electrical components inside the control cabinet, such as circuit breakers, relays, etc., to ensure there are no abnormalities.

5. Regular operation: During the holidays, run the CNC vertical lathe regularly to ensure that all parts of the CNC vertical lathe are properly lubricated and moved, and to prevent parts from rusting or getting stuck due to long-term outage.

6. Environmental control: Set up appropriate environmental control measures around the CNC vertical lathe to ensure that the temperature and humidity are within an appropriate range to prevent the CNC vertical lathe from getting damp, rusty or other environmental influences.

7. Turn off the power: When not in use for a long time, turn off the power of the CNC vertical lathe and unplug the power plug to avoid electrical failures and safety hazards.

8. Record the maintenance status: Record the maintenance status of the CNC vertical lathe, including cleaning, lubrication, inspection, etc., for reference and review when resuming work.

Through the above maintenance measures, the CNC vertical lathe can be effectively protected, maintained in good condition during the holidays, and provide reliable performance when work resumes.
