Zusammenfassung:	The present disclosure relates to a process of machining a metal middle frame, which includes the following steps of: obtaining a sheet material and cutting the sheet material into a linear profile; performing a finish machining to the linear profile; bending the linear profile after the finish machining, obtaining a metal border frame with an R angle; welding the metal border frame; and placing the metal border frame after the welding in a die-casting mold, providing a die-casting metal liquid, thereby obtaining a die-cast middle plate connected to the metal border frame, so as to form the metal middle frame.
