The lubrication cycle is to ensure that the various components of the machine and equipment are in good lubrication condition during operation, thereby ensuring the stability and life of the equipment. For two-column CNC vertical lathes or CNC vertical lathes, the lubrication intervals are usually based on the manufacturer's recommendations and the usage of the specific equipment.
Generally, the lubrication interval depends on the following factors:

1. Manufacturer’s Guidelines: Equipment manufacturers often provide recommended lubrication intervals in the equipment’s operating manual or maintenance manual. These cycles may be based on usage time, the total number of cycles the device has been run, or a specific number of operations.
2. Working environment conditions: If the equipment is operated in a harsh environment, such as high temperature, high humidity, dusty or multi-metallic cutting agents, lubrication cycles may need to be performed more frequently.
3. Equipment usage: If the equipment frequently performs heavy cutting or high-speed operation, more frequent lubrication may be required to ensure good lubrication of each component.
4. Lubrication system type: Different CNC vertical lathes may use different types of lubrication systems, such as manual lubrication systems or automatic lubrication systems. The automatic lubrication system can adjust the lubrication cycle based on set parameters and equipment usage.

Therefore, there is no fixed standard for the lubrication cycle. The optimal lubrication cycle should be based on the above factors and follow the equipment manufacturer's recommendations. Before using your equipment, it's a good idea to read the equipment manual in detail to understand the manufacturer's recommendations and recommendations for lubrication intervals. At the same time, regularly check the wear status of the lubrication system and components, and adjust the lubrication cycle according to the actual situation to ensure the normal operation and service life of the equipment.
