The present invention refers to a been processed after the origin point of the rack gear required by simply set a more easily, quickly and precision machining is done to increase the productivity and quality than the pinion gear can be significantly contribute to new method and device are disclosed to the fiber surface. I.e., the present invention refers to working machine (such as NC or CNC machine) collet chuck for fixing tool of pinion gear is used to fix, origin is obtained when setting tool (cutting tool) in a conventional method to be made improve the corresponding staple fiber in pinion gear, said pinion gear when fixing processing of collet chuck decorate, formed around the edges of the rack gear constant interval between which the plurality of light sources also conformal field gear for setting contacts following which it should above origin (200) to corresponding setting can be made automatically in origin are disclosed.
