Classification of common faults of CNC machine tools

1. Deterministic failure

Deterministic failure refers to the failure of the CNC machine tool if the hardware in the host computer of the control system is damaged or as long as certain conditions are met. This type of failure phenomenon is the most common on CNC machine tools, but because it has certain rules, it also brings convenience to maintenance. Deterministic failures are irrecoverable. Once a failure occurs, if it is not repaired, the machine tool will not Automatically return to normal. But as long as the root cause of the failure is found, the machine tool can be restored to normal immediately after the repair is completed. Correct use and careful maintenance are important measures to prevent or avoid failures.cnc machine service。

2. Random failure

Random failures are accidental failures of exponential control machine tools in the working process. The causes of such failures are relatively hidden, and it is difficult to find out its regularity, so it is often called “soft failure”. Random failure analysis and fault diagnosis It is more difficult. Generally speaking, the occurrence of faults is often related to many factors such as the installation quality of the components, the setting of parameters, the quality of components, the imperfect software design, and the influence of the working environment. Random failures are recoverable. After a failure occurs, the machine tool can usually be restored to normal by restarting and other measures, but the same failure may occur during operation.

Strengthening the maintenance and inspection of the CNC system, ensuring the sealing of the electrical box, reliable installation, connection, and correct grounding and shielding are important measures to reduce and avoid such failures.
