Summary:The invention in particular relates to a precision machining method for a long and thin shaft of a cross-shaped wing bearing, which aims at solving the problem that precision is difficult to guarantee when a long and thin shaft of an existing cross-shaped wing bearing is processed. The precision machining method comprises the following steps: a, arranging a plurality of aluminum block fixtures composed of an aluminum block body on a working table of a machine tool; b, processing workpiece placing slots in the upper surfaces of the middle parts of two aluminum block fixtures; c, mounting on the workpiece placing slots by taking a work piece left wing end face as a positioning reference surface, and gluing at a seam by adopting 502 quick-dry super glue until a workpiece is fixed and then loosening the workpiece; d, after the positioning reference surface of the workpiece is checked to be qualified with a meter, starting to carry out finish machining; e, sequentially processing the upper wing end face, the left
