According to the nature of the failure of the CNC machine tool.
(1) Deterministic failure: refers to failure as long as the conditions are met; For example, if the voltage load is too high, an alarm is raised.
(2) Random fault: refers to the random issuance of one or two alarm signals under the same conditions; Such faults are difficult to analyze and troubleshoot; This kind of failure is generally related to mechanical structural parts and CNC system parts.
Categorized by fault type
(1) Mechanical failure: refers to the host part of the machine tool. Common faults mainly include: mechanical transmission failures caused by irregular installation, debugging and operation of mechanical parts; failures caused by interference and excessive friction of moving parts such as rails and spindles; due to damage to mechanical parts; Failures caused by poor connectivity and so on.
