The maintenance method of CNC vertical lathe involves many aspects. The following are some key steps and precautions:

1. Daily cleaning: Clean the CNC vertical lathe regularly, including the machine tool body, workbench, fixtures, tools, etc. Make sure there is no dust, chips and oil on the surface and inside of the CNC vertical lathe. Pay special attention to cleaning guide rails, sliders and other parts that are susceptible to contamination. Keeping CNC vertical lathes clean and tidy helps prevent corrosion and ensure machining accuracy.

2. Lubrication and maintenance: Regularly check the lubrication system of CNC vertical lathes to ensure that the lubricating oil is sufficient and clean. According to the usage and requirements of the machine tool, the lubricating oil should be replaced regularly to ensure good lubrication effect of each component. Poor lubrication of CNC vertical lathes may lead to component wear and failure, so lubrication and maintenance are an important part of maintaining CNC vertical lathes.

3. Parts inspection and replacement: Regularly check the wear and tear of various parts of the machine tool, such as the transmission system, spindle, guide rail, etc. Once seriously worn parts are found, they should be replaced in time to avoid machine tool failure due to damage to parts. At the same time, a spare parts reserve plan for commonly worn parts of CNC vertical lathes has been established to ensure that they can be replaced in time when replacement is needed and to reduce downtime.

4. Electrical system inspection: CNC vertical lathes regularly check whether the connection of the electrical system is firm, whether the cables are worn, and whether the electrical components are working properly. Repair electrical system problems in a timely manner to ensure the safe and stable operation of CNC vertical lathes. Electrical faults may cause machine tool shutdown or even damage, so electrical system inspection is an important part of maintenance work.

5. Positioning accuracy calibration: Calibrate the positioning accuracy of the CNC vertical lathe regularly to adjust the position error of each axis to ensure that the processing accuracy and repeated positioning accuracy meet the requirements. The decrease in the accuracy of CNC vertical lathes will affect the processing quality and efficiency, so regular calibration is a key measure to maintain the accuracy of CNC vertical lathes.

6. Operating procedures and training: Ensure that CNC vertical lathe operators are familiar with the structure, performance, functions and operating procedures of the CNC vertical lathe, and can only operate after passing the training. Operators should strictly follow the operating procedures to avoid equipment damage caused by misoperation. At the same time, CNC vertical lathes must pay attention to safe operations and take corresponding protective measures, such as wearing protective glasses and gloves.

To sum up, the maintenance methods of CNC vertical lathe include daily cleaning, lubrication and maintenance, parts inspection and replacement, electrical system inspection, positioning accuracy calibration, operating procedures and training, etc. Through the implementation of these maintenance measures, the normal operation of the CNC vertical lathe can be ensured, the service life can be extended, and the processing accuracy and efficiency can be improved.
