The invention provides a method for machining a slender hole in a machining center to guarantee the form and location tolerance of the slender hole, and the method adopts a rough-fine combined mode for machining according to the size and depth of the slender hole. During rough machining, a centering drill is selected to fix the rough reference position, it can be guaranteed that a cutter is not broken, the surface roughness in a hole can also be guaranteed, and an accurate reference is established for follow-up machining; during finish machining, different types of cutters are selected for combined cutting according to different effects of cutter blades participating in cutting, the cutters are protected, the cutter breakage phenomenon is not prone to occurring, the service life of the cutters is guaranteed, and the size precision and the position precision of machined holes are also guaranteed. During final forming machining, a drilling reamer is selected for machining; and the aperture size is ensured, and
