How to Observe the Failure Phenomenon in Precision Machining?

2022-01-17

In the processing of precision parts, the fixture of the milling machine fails, and there are some obvious failure phenomena, such as the machining accuracy of the parts cannot be guaranteed, the clamping of the parts is not reliable, some components of the fixture are damaged and severely worn, and the devices and mechanisms cannot achieve operational functions. At this time, it is mainly through detection, observation and experimental operation to preliminarily determine the main cause of the fault.

Analysis of the cause of the failure: If the various failures of the milling machine fixture are caused by a single cause, the analysis can be carried out according to the general rules. For example, the parts are displaced during the processing process, and the cause may be the failure of the clamping part; precision parts There are regular deviations in the dimensional accuracy of machining, which may be caused by the decline and looseness of the positioning components of the parts; the deviation of the machining accuracy of the parts is consistent, which may be caused by the failure of the tool setting device. If it is caused by multiple reasons, it is necessary to analyze the above single reason before further analyzing the relevant reasons. For example, it is found that the position accuracy of the plane milling fixture has decreased, which may be caused by the wear of the top of the support and limit element, and the imbalance of the linkage clamping mechanism.
