The invention belongs to the technical field of copper-aluminum composite pole machining and discloses a machining method of a copper-aluminum composite pole. The machining method comprises the following steps of: S1, a copper block and an aluminum block are separately machined, and the thickness of the copper block is smaller than that of the aluminum block; S2, the copper block and the aluminum block are assembled into a composite block through one of a hot pressing process, a brazing process and an electric resistance welding process; and S3, the composite block is machined into the copper-aluminum composite pole by adopting a cold heading process. According to the machining method of the copper-aluminum composite pole disclosed by the invention, the copper block and the aluminum block are machined, and the price of the aluminum block is far lower than that of the copper block, so that the total price of the copper block and the aluminum block is lower than that of an existing composite board, and the mach
