CNC plasma cutting machineIt is one of the necessary equipment in the processing of mechanical equipment. It controls the movement of precision machinery through a computer and a servo system to cut any graphics quickly and accurately. CNC plasma cutting machine is a set of CNC technology, computer hardware and software technology, plasma cutting technology and precision machinery technology in one of the high-tech.

Once the CNC plasma cutting machine equipment fails, it will not be able to successfully complete the original work, resulting in downtime or failure to achieve the intended work effect. According to the damage degree of CNC plasma cutting machine equipment failure, it is divided into two types, one is fatal failure, the other is non-fatal failure. Fatal failure is not only can not successfully complete the intended work objectives, but also cause significant loss of people or things, resulting in the failure of the task. Non-fatal failure will not bring the loss of people and things, but will bring harm to the machine tool and equipment. If the non-fatal fault cannot be repaired in time, it will develop into a fatal fault.

According to whether the equipment failure of the CNC plasma cutting machine is its own cause or other related equipment, it is divided into independent failure and dependent failure. According to the number and frequency of CNC machine tool equipment failures, it can be divided into early failures, accidental failures and wear failures.

　CNC plasma cutting machineThe faults that occur during the application process are difficult to confirm. During the fault diagnosis process, it is necessary to ensure that the equipment will not be damaged more seriously. At this time, a backup control board can be used instead of the control board that is considered to be faulty. Through the application of the standby control board, the normal operation and work progress of the equipment are guaranteed. At the same time, in the process of replacing the same type of basic control board, the efficiency of the control board system detection can be further improved.

Many imported CNC plasma cutting machines have a self-diagnostic function, which is an important criterion for determining the performance of CNC machine tools. For such a CNC machine tool, it is easier to diagnose when a fault occurs. Because once this kind of machine tool fails, some fault indication or display of the CNC machine tool will indicate the location of the fault or the cause of the fault. In this way, the problem of the machine tool can be found in time and the problem can be solved quickly. However, this self-diagnosis function is only available in some high-end CNC machine tools, and ordinary CNC plasma cutting machines do not have this function.

　CNC plasma cutting machineThe reason for the failure is that some logical functions of mechanical equipment cannot guarantee the predetermined functions during operation, and abnormal operation occurs. Therefore, in the process of fault diagnosis, the inherent principle diagram of the machine can be used for fault diagnosis, such as the application of electrical schematic diagram, PLC program and hydraulic schematic diagram. So as to quickly find the cause of the failure. And repair and replace the faulty parts, so that the CNC plasma cutting machine can return to normal working condition in a short time, and try not to affect production.
