What inspections need to be done after precision machining

First, check the mechanical properties


When inspecting, it is necessary to combine the characteristics of mechanical overhaul to perform performance inspection on the produced parts. In addition to looking at its hardness, other indicators generally do not need to be specially inspected. However, if it is Some performance abnormalities are encountered during the manufacturing or overhaul of parts, so they cannot be ignored. Common abnormalities include balance conditions or spring stiffness, etc. If these performance abnormalities may directly affect the normality of the parts Use it, and you must not let it go during inspection.





Second, check for hidden defects





In the process of precision machining, there may be defects such as impurities or voids in the parts, and the appearance of such defects will lead to relatively subtle cracks during production. If these cracks are simply passed It is difficult to find out by observation or measurement, but it will have a serious negative impact on the machine. Therefore, it must be inspected for hidden defects during inspection.
