Abstract
A tool holder () comprising: an outside section () connected and fixed to a main shaft housing; a rotation input section () that is gripped by the main shaft and caused to rotate at a first rotation speed r; a rotation output section () that has the rotational force from the rotation input section () transmitted thereto and rotates at a second rotation speed rthat is different from the first rotation speed r; a slider () that is moved in a first direction that intersects the rotational axis (Os) of the main shaft, as a result of the force from the rotation output section (); a cutting edge () that is moved in the first direction by the slider () and is rotated by the rotation input section (); and a detection mechanism () for detecting that the cutting edge () is at the origin position.
