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.
A metallic frame is characterized that the frame is formed by forging and precise machining a workpiece, and the forging process is performed before precise machining, 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.
A method of making a metallic frame, 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 method comprising:
