Metallic frame and method of making the same

摘要

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.
