The center of the reamer can always be consistent with the center of the hole to be machined during the entire reaming process; it can make the clamped reamer automatically find the center of the hole to be machined to ensure that the center line of the reamer is parallel to the center line of the hole to be machined; it can reduce error and vibration and prolong the life of the tool.
