The turn-milling compound machine tool is a machine tool that integrates the functions of a lathe and a milling machine. In order to ensure its normal operation and extend its service life, the following are some maintenance tips for the turn-milling compound machine tool:

1. Cleaning and maintenance: Clean the machine tool regularly, including removing dust and debris on the surface of the machine tool, cleaning chips, lubricating oil and coolant, etc. Use a soft cloth or brush for cleaning, but avoid using corrosive solvents.
2. Lubrication maintenance: Ensure normal lubrication of all lubricating parts of the machine tool, including guide rails, screws, transmission chains, etc. According to the requirements of the machine tool specifications and operating manual, add lubricating oil or grease regularly, and pay attention to the purity and quality of the lubricating oil.
3. Check the transmission system: Regularly check the transmission system of the turning and milling machine tool, including the motor, transmission belt, gear and transmission shaft, etc. Ensure the normal operation of the transmission system and the safety and reliability of fasteners.
4. Check the cutting tools and tool holders: Keep the cutting tools and tool holders clean and in normal condition. Check the wear of the cutting tools regularly, replace severely worn or damaged cutting tools in a timely manner, and avoid using damaged tool holders.
5. Check the electrical system: Regularly check the electrical system of the turning and milling machine tool, including cables, switches, fuses, etc. Make sure the electrical connections are good and eliminate possible electrical faults.
6. Keep the machine tool stable: When using the turning-milling compound machine tool, keep the machine tool running smoothly and avoid severe shock and vibration to reduce wear and damage of machine tool parts.
7. Regular maintenance: According to the maintenance manual and recommendations provided by the machine tool manufacturer, formulate a regular maintenance plan and perform necessary maintenance work, such as lubricating oil replacement, fastener inspection and tightening, etc.
8. Protection during shutdown: When the machine tool is shut down, cover the machine tool or use a dust cover to prevent dust and debris from entering the inside of the machine tool.

The above are some maintenance tips for turn-mill machine tools, but specific maintenance requirements may vary depending on the machine model, manufacturer and usage. Therefore, it is recommended to develop a personalized maintenance plan suitable for the machine tool based on the specific requirements of the machine tool and the manufacturer's recommendations, and perform regular maintenance and inspections. If necessary, you can consult the machine tool manufacturer or professional technicians for more detailed maintenance instructions.
