The invention discloses a machining process of an ultra-thin jack guide end cover. The machining process is characterized by comprising the following steps that rough machining is conducted on a workpiece through a machine tool to form a guide cover and a guide sleeve; internal threads and external threads are machined on the guide cover and the guide sleeve through a machine tool; the internal thread of the guide cover and the external thread of the guide sleeve are coated with anaerobic adhesive; the guide sleeve coated with the anaerobic adhesive and the guide cover are connected through thread fit of the internal thread and the external thread; the guide sleeve is expanded outwards through hydraulic equipment, so that the guide sleeve and the guide cover are connected and clamped; and the guide cover and the guide sleeve which are connected and clamped are subjected to finish machining through a machine tool. The guide cover and the guide sleeve are connected through the threads, and then the guide sleeve
