The method is used for machining radiant ray detection measuring tools.

Description

Technical field [0001] The invention relates to a method for processing radiation detection measuring tools. Background technique [0002] At present, after the processing of the root of the trapezoidal revolving surface of the steam turbine blade is completed, it is necessary to check whether the position of the root and the radial line is correct to ensure the assembly requirements. During the test, a special radiation detection gauge is used for detection, and the radiation detection gauge is the main component. , Looks like Figure 4~6 As shown, the arc trapezoidal groove is a difficult point in processing, and the accuracy is difficult to guarantee. In order to ensure the processing quality and accuracy of the radiation detection gauge, it is necessary to develop a radiation detection gauge processing method. [0003] In summary, it is difficult to ensure the dimensional accuracy of the arc trapezoidal groove by using the existing radiation detection measuring tool processing m...
