Diagnosis and Maintenance Sample of CNC Machine External Fault
Computer numerical control machine tools have great advantages in machining accuracy, speed, and various functions. The high precision parts machined by CNC machine tools achieve a higher level of processing, which greatly reduces the labor intensity of workers and greatly increases the production efficiency. CNC machine tools are widely used in many industries, but in actual use, users will also encounter some fault problems caused by the external reasons of CNC machine tools. So how do we diagnose and repair the external fault of CN C machine tool? Below is an instance of CNC machine external fault diagnosis and maintenance.
Case Description:
Recently, the use department reported a malfunction of the CNC machine external fault. After inspection, it was found that the CNC machine tool did not move and vibrated frequently when working. The inspection personnel found that the exterior cooling fan of the CNC machine tool was not running normally.
Diagnosis:
The exterior cooling fan of the CNC machine tool is not running properly, which can be part of the source of the external fault of the CNC machine tool. If the cooling fan of the CNC machine tool is not working properly, the external temperature of the CNC machine tool will be gradually increased, then the lubricant in the transmission components of the CNC machine tool will appear dry phenomenon, resulting in a significant increase in friction between the transmission components or between the parts and the transmission components. which causes frequent vibration when the CNC machine tool is working. Therefore, it can be inferred that the abnormal phenomenon of non-working of the external cooling fan is the cause of this external fault.
Maintenance:
The malfunction of the exterior cooling fan of the CNC machine tool was diagnosed and concluded. Because it is relatively simple to maintain the cooling fan, the CNC machine repair personnel directly checked the cooling fan and found that the exterior surface of the cooling fan was covered with a layer of dust, which could cause the cooling fan to fail. Therefore, the repair personnel directly took measures to clean the dust of the cooling fan, and then took measures to repair the stator and blades of the cooling fan. Finally, the CNC machine repair personnel turned on the cooling fan and verified that the cooling fan was working normally.
Conclusion:
In this case of CNC machine external fault, after the repair personnel carefully diagnosed and checked the external cooling fan of the CNC machine tool, it is concluded that the failure of the cooling fan is the cause of the external fault of this CNC machine tool. This shows that when the external fault of the CNC machine tool appears, it is necessary to carry out relevant maintenance and inspection work to ensure its normal operation, and timely clean and maintain its external equipment to ensure its stable operation.
