Requirements of the Blank
Mar,10 2020
Requirements of the Blank In the spinning, especially in the process of shear forming, the blank bears a lot of pressure from the spinning tool and core mold, then produces severe local deformation. Its surface and internal defects of the blank will be enlarged, causing the workpiece to be scrapped. In addition, the manufacturing accuracy of the blank, the heat treatment method, and the physical properties of the material will also affect the quality and economic effects of the spinning parts. T
