Abstract: An exemplary metallic frame (60) is formed by forging and precise machining of a workpiece. The forging process is performed before the precise machining process, a hardness of the frame is larger than that of the workpiece and a surface roughness Ra of the frame reaches about 6.4 microns. The present invention further provides a method of making the frame. The method includes as follows: feeding workpiece process (12) for providing a workpiece (20); forging process (14), the workpiece be forged to form a preform (40); and precise machining process (18), the preform be precisely machined to form a frame.
