The invention relates to a method for machining a deep hole conical surface, and belongs to the technical field of machining. Comprising the following steps: 1, boring center holes in two ends of a to-be-processed part, performing flaw detection and heat treatment on the part, roughly processing an outer circle by taking the center holes as a reference, aligning and clamping the part by taking the outer circle as a reference, drilling, boring and honing to process small holes in place; step 2, roughly machining an outer circle by taking the small hole as a reference, boring each step of the conical surface part of the inner hole of the part by using a deep hole drilling and boring machine, roughly machining the conical surface of the deep hole by using a rough machining conical surface boring head device, and carrying out finish machining by using a finish machining conical surface boring head device after the machining is finished; and 3, honing the large hole after the deep hole conical surface is machined,
