Cutting edge grinding device of single crystal diamond spiral cutter

The invention provides a cutting edge grinding device of a single crystal diamond spiral cutter, and belongs to the technical field of spiral cutter grinding. The cutting edge grinding device of the single crystal diamond spiral cutter comprises a supporting base, a sliding shaft is slidably connected to the interior of a supporting ring, a driving assembly is arranged at one end of the sliding shaft, and a grinding assembly is arranged at the bottom of an adjusting rod; the two grinding thick heads can roughly grind the cutting edge of the spiral cutter, the grinding efficiency is improved through primary grinding, the two grinding thin heads can finely grind the cutting edge of the spiral cutter, the smoothness of the grinding face is improved, and the sharpness of the cutting edge of the spiral cutter is improved; air flow enters the interior from the staggered position between the thick grinding head and the thin grinding head through the rotating speed of the air guide plate, then the internal air flow i
