Deep hole drilling method and deep hole drilling shank

The invention relates to the technical field of mechanical drilling, and discloses a deep hole drilling machining method and a deep hole drilling cutter handle, a drill bit is driven by the cutter handle to rotate to machine a workpiece, a curve path is set, the cutter handle operates around the curve path, the drill bit is driven to make intermittent contact with the workpiece, and the curve path is a regular wavy line. Wave crests and wave troughs of the wavy lines are symmetrical, and the orientations of the wave crests and the wave troughs are parallel to the axial direction of the cutter handle. According to the machining method, the curve path for the cutter handle to operate along the path in the rotating process is innovatively designed, the cutter handle drives the drill bit to do periodic reciprocating motion in the axial direction of the cutter handle, the drill bit makes periodic contact with or does not make contact with a workpiece, then small chips are generated, the ideal chip breaking and smo
