The processing method and steps of the failure of the CNC drilling machine.

      1 Make full use of the CNC system hardware and software alarm function 

There are many hardware alarm indicating devices in the modern numerical control system, and the setting of hardware alarm indicating devices is beneficial to improve the maintainability of the numerical control system. The CNC system of the CNC machine tool has a self-diagnosis function. During the working period of the CNC system, the self-diagnosis program can be used in time to quickly diagnose the system. Once a fault is detected, it will immediately display the fault on the CRT as an alarm or light up the alarm indicator light on the panel. Moreover, this self-diagnosis function can also classify faults as alarms.     |

       2 The method of simple fault alarm processing of CNC machine tools

Generally, CNC machine tools have a strong self-alarm function, which can monitor the working status of system hardware and software at any time. Most of the faults of CNC machine tools can display alarm prompts. According to the fault prompts, the faults of the machine tools can be determined, and timely processing and troubleshooting can be achieved. Machine tool availability and efficiency.    

       3 direct observation method     

The direct observation method is to use human sensory organs to pay attention to various external phenomena when a fault occurs (or after a fault occurs) and to judge the possible location of the fault. This is the first entry point to deal with CNC system faults, and it is often a direct and effective method. For "simple" faults under normal circumstances, the problem can be solved through this direct observation.     |

       4 The method of judging the fault by using the status display diagnosis function  

The modern numerical control system can not only display fault diagnosis information, but also provide various states of diagnosis in the form of diagnosis address and diagnosis data.     |

       5 When a fault occurs, check the CNC system parameters in time to judge the fault method  

The parameter change of the CNC system of the CNC machine tool will directly affect the performance of the CNC machine tool, causing the CNC machine tool to break down, or even the whole machine cannot work normally. Therefore, in the process of analyzing and diagnosing faults, even though some measures have been taken, if the problem still cannot be solved or the fault is eliminated, or the source of the fault is not clear enough, you should change your thinking and start from what people call "soft" faults. Check and check the parameters of the CNC system, whether it is the fault caused by the change of the parameters of the CNC system, it is often a trace of abnormality, which is the crux of the problem.
