Host failure
The main performance of the main engine is high transmission noise, poor machining accuracy, high running resistance, mechanical parts do not move, mechanical parts are damaged, etc. Poor lubrication, pipeline blockage and poor sealing of hydraulic and pneumatic systems are common causes of host failure. The regular maintenance, maintenance, control and eradication of the "three leaks" phenomenon of CNC machine tools are important measures to reduce the failure of the host part.
Deterministic failures
Deterministic faults are unrecoverable, and once a fault occurs, the machine will not automatically return to normal if it is not repaired. However, as long as the root cause of the failure is identified, the machine can be restored to normal as soon as the repair is completed. Proper use and careful maintenance are important measures to prevent or avoid failures.
Random failures
Incidental failures. The cause of the fault is relatively hidden, and it is difficult to find out its regularity. Generally speaking, the occurrence of faults is often related to many factors such as the installation quality of components, the setting of parameters, the quality of components, the imperfect software design, and the influence of the working environment.
