PROBLEM TO BE SOLVED: To install/remove a wheel mount to/from a rotation shaft, by matching a center of the wheel mount to a center of the rotation shaft.SOLUTION: An attaching/detaching tool 1 is composed of a shaft 2 formed with a male screw portion inserted in a fastening hole 14 of a female screw of a rotation shaft 11A in the whole area in a longitudinal direction; and a positioning nut 3 equipped with a female screw portion in which the male screw portion of the shaft 2 is inserted. The positioning nut 3 is equipped with a rotating grip portion 3a, and a tapered portion 3b for positioning, so that the positioning nut 3 of the attaching/detaching tool 1 can match a center axis 4 of the rotation shaft 11A to a center of a wheel mount 15, thereby bringing close/separating a first fastening surface 11a of the rotation shaft 11A to/from a second fastening surface 16 of the wheel mount 15 in parallel. When a grinding wheel is installed to the wheel mount to machine platy work, vibrations due to high-speed rotations of the grinding wheel can be suppressed, and the generation of unevenness in the thickness of the platy work can be prevented. |
