Key points for semi-annual maintenance of CNC machine tools

Key points for semi-annual maintenance of CNC machine tools

1. Comprehensively check and tighten all wiring terminals, and replace corroded or damaged parts in time.

2. In-depth test of motor insulation resistance to ensure that the motor can operate safely and stably under various environments.

3. Conduct a comprehensive and in-depth physical examination of the hydraulic system, including the stability of working pressure and flow, and the cleanliness of the hydraulic oil tank.

4. Completely replace the breathing filter of the hydraulic oil tank to ensure that its filtering effect is in the best state.

5. Test all switches and buttons one by one to ensure that they are responsive and function well.

6. In-depth and detailed inspection of the wear condition of the machine tool spindle and guide rails, and record the inspection results in detail to provide strong support for subsequent maintenance.

1. Disassemble the anti-chip shields of the X, Y, and Z axes, thoroughly clean the oil pipe joints, ball guide screws, and limit switches of the three axes, and carefully check whether their performance is normal. At the same time, check whether the cleaning effect of the hard rail scraper of each axis meets the standard.

2. Perform a comprehensive inspection of the servo motors and heads of each axis to ensure that they operate normally and without abnormal sounds.

3. Replace the oil of the hydraulic unit and the lubricating oil of the tool magazine reduction mechanism.

4. Perform a detailed test on the clearance of each axis and adjust the compensation amount as needed to ensure the accuracy of the machine tool.

5. When the CNC machine tool is turned off, clean the dust inside the electrical box to keep the electrical components clean and in good condition.

6. Perform a comprehensive inspection of all contacts, connectors, sockets and switches to ensure that they function normally and are safe and reliable.

7. Check and adjust the horizontal state of the machine to ensure the stability and processing accuracy of the machine tool.
