1. For CNC drilling machines that have been used for a long time, it is advisable not to shut down the machine during long holidays, and emergency stops can be recorded.
2. Regularly check the system fan. If there is too much oil contamination, it should be replaced or cleaned. If it has been used for more than 3 years, it must be replaced.
3. Regularly check the hydraulic pressure, liquid level, and hydraulic impurities in the hydraulic system to ensure smooth oil passages.
4. Regularly clean or lubricate devices with springs such as feed switches, knife arm springs, hydraulic valve springs, etc.
5. Regularly clean the CNC drill drive equipment.
6. Regularly replace the system battery and desiccant of the machine tool electrical cabinet, especially before shutting down during long holidays.
After the long vacation, before restarting, manually preheat each circuit board of the machine tool. You can use a hair dryer to heat each circuit board of the CNC drill for a few minutes, slightly warming it up
