Routine maintenance and upkeep of CNC machine tools includes the following:

1. Cleanliness and hygiene: Keep the machine tool clean, including regularly removing chips and debris, cleaning the machine tool surface and work area, and maintaining a tidy working environment.
2. Lubrication system maintenance: Regularly check and replace lubricating oil and grease to ensure the normal operation of the lubrication system and maintain good lubrication status of the machine tool.
3. Electrical system maintenance: Regularly check the electrical system, including checking cable connections, plugs and switches, to ensure the reliability and safety of electrical lines.
4. Transmission system inspection: Regularly check the transmission system of the machine tool, including gears, transmission belts, screws, etc., to ensure that the transmission system operates normally and is not loose.
5. Inspection and replacement of cutting tools: Regularly check the wear of cutting tools and promptly replace severely worn tools to ensure the processing quality and accuracy of workpiece dimensions.
6. Cleaning and lubrication of guide rails and screws: Clean and lubricate guide rails and screws regularly to ensure smooth surfaces and reduce wear.
7. Cooling system maintenance: Clean and flush the cooling system regularly, and replace the coolant to ensure that the cooling system can effectively cool the tool and workpiece.
8. Regular calibration and adjustment: Regularly calibrate machine tools, including checking geometric accuracy, tool position, tool compensation, etc., to ensure the processing accuracy of machine tools.
9. Maintenance records and maintenance plans: Establish maintenance records for machine tools and record the time, content and results of each maintenance and maintenance. Develop maintenance plans and perform and track maintenance work as planned.
10. Training and operating specifications: Ensure that machine tool operators are fully trained and familiar with machine tool operating specifications and safe operating procedures to reduce misoperation and damage to machine tools.

The above are the general cms_contents of daily maintenance and upkeep of CNC machine tools. The specific maintenance and upkeep cms_contents may vary depending on the machine tool model, manufacturer and usage. Machine tool manufacturers often provide detailed maintenance manuals and guides, and it is recommended to follow the machine tool manufacturer's recommendations and requirements for maintenance and upkeep work. If necessary, you can consult the machine tool manufacturer or professional maintenance personnel for more specific maintenance guidance and support.
