CNC milling machine has a problem that the × axis cannot move during work.

Failure analysis: First, the X-axis motor and cable were checked, and no problems were found. Then I checked the X-axis guide rail and found that there were some iron filings and oil stains on the guide rail, which may prevent the guide rail from moving normally. After cleaning and lubrication, the guide rail returned to normal.

Maintenance process: First turn off the power and ensure that the machine tool is in a safe state. Then remove the X-axis guide rail and clean the iron filings and oil on the surface of the guide rail. Then apply lubricating oil on the surface of the rail to ensure that the guide rail can move normally. Finally, reinstall the guide and enable it.

The power supply was tested and it was found that the X-axis returned to normal.

Maintenance summary: CNC machine tools are high-precision mechanical equipment, and the causes of failure may be complicated. During the repair process, each component needs to be carefully inspected to find out the cause of the failure. In addition, you need to pay attention to safety during maintenance to avoid accidents.
