The fine blanked part with edge chamfer must be manufactured by the combination with extrusion or cold forging. Some problems, such as the remarkable deviation of material feed step and part chamfer angle, etc., were emerged due to the unbalanced forming force，which lead to unqualified part. Using the brake back shoe which was a typical fine blanking part with edge chamfer as object, a new approach was discussed for the fine blanking of this part based on a series of researches, and a 4 steps progressive fine blanking die was designed and manufactured. Further more, qualified back shoe was produced by this approach. A new independent lubrication device was put forward for the elongation of tool life. The research results can be widely used in the fine blanking development for similar parts.
