Calibration method for length cutter compensation of taper reamer

The invention relates to the technical field of taper hole machining, in particular to a taper reamer length cutter compensation and calibration method, which comprises the following steps of: before replacing a taper reamer, sleeving a taper hole calibration ring gauge on an old taper reamer, detecting the position of the end surface of the taper hole calibration ring gauge, then replacing the taper reamer, sleeving the taper hole calibration ring gauge on a new taper reamer, and calibrating the taper reamer length cutter compensation and calibration method. Detecting the position of the end face of the taper hole calibration ring gauge again, and adjusting the position of the taper reamer to enable the positions of the end faces of the taper hole calibration ring gauge detected twice to be the same; the taper hole correcting ring gauge is a cylinder, and a taper hole with the same taper as the taper reamer is formed in the middle of the taper hole correcting ring gauge. The blade position of the taper reame
