Embodiment 1
[0042] When specifically using the machining process preparation method of the parts provided by the invention:
[0043] 1. Analyze the part drawings and structural processability of the impeller JHE50-2250-02, and clarify the technical requirements of the drawings include: the maximum outer diameter Ф259 and the total width 95, the processing parts are all outer contours, 4 Ф9 holes and Ф32 inner holes and keyways ; The maximum beating is 0.04, the roughness of the mating parts is 3.2, and the rest parts are 12.5. The structure of the processing part can be realized through technological analysis.
[0044] 2. After measuring and confirming the blank of the part, the blank type, material (hardness), margin, shape, size and precision are clarified; the blank of the impeller JHE50-2250-02 is a casting, the precision is low, the material is 316, and the blank is just a round shape Outline, no center hole, large margin, 15mm on one side.
[0045] 3. After confirming the blank ty...
