Summary:The invention relates to the field of machining, in particular to a method for rapidly machining a counterbore. The defect that the counterbore efficiency is low is overcome, and large-scale application of a countersunk screw pressing mode is powerfully boosted. When the counterbore drill bit is used for machining a counterbore, a machine tool is stable in cutting and high in cutting efficiency. And short-distance circulating layered drilling is not needed during processing. The blank with the thickness of less than 40 mm supports one-time direct drilling to the bottom, and the blank with the thickness of more than 40 mm supports large-distance circulating layered drilling. The machining time of a single counterbore is about 10 seconds, and the efficiency is improved by at least 12 times. And the processed counterbore is good in quality, a large hole and a small hole are formed at one time, and the coaxiality is ensured. 本发明涉及机械加工领域，尤其是涉及一种快速加工沉头孔的方法。本发明规避了沉头孔效率低下的缺陷，有力助推沉头螺钉压紧方式的大量应用。采用本沉头孔钻头加工沉头孔时，机床切削平稳，切削
