A METHOD AND AN APPARATUS FOR PROCESSING FRACTURE SURFACES OF FRACTURED DUCTILE METAL PARTS, AND A METHOD AND AN APPARATUS FOR MANUFACTURING FRACTURED AND FRACTURE SURFACE-PROCESSED DUCTILE METAL PARTS

摘要

Flexible metal part 50 of the cutting plane (51a, 52a) to the fracture surface treatment method of the rupture of the flexible metallic components to process, fracture surface (51a, 52a) on the relevant through-hole of the flexible metal parts having a through hole put into the semi-split type mandrel of the split in half, the art half and the broken cutting plane by putting driving a wedge between the dividing of the mandrel, the rupture of a flexible metallic component 50 relevant cutting plane (51a, 52a) is attached to the same time for holding respectively, in which spaced apart so as to maintain a constant gap state, the cutting plane by applying a predetermined vibration in a direction crossing the fracture direction relative to the at least either one of the rupture of a flexible metal part (50) (51a, 52a) removed the breaking powder (59), and a result, enables an optimal surface alignment when a back surface of the cutting plane of the rupture ductility metal parts alignment.
