CASING PROCESSING METHOD USING THE MOLD

摘要

PURPOSE: A casing processing method using a mold is provided to minimize the crack generation of fastening part by improving the machining accuracy of the fastening part. CONSTITUTION: The processed product is in thrown(S10). A first fastening part is processed at the first(S20). The first processing surface of the first fastening part is finishing-processed(S30). The first fastening part secondary operation and a second fastening part first processing surface are processed(S40). The second fastening part first processing surface be finishing-processed(S50). The second fastening part secondary operation and the second fastening part third operation post processing side be finishing-processed(S60). A slope angle of the first fastening part is processed(S70). The processed product is the austenite series.
