になる。As described above, the present invention (claim 1)
The thin blade grindstone mounting structure is such that the thin blade grindstone is fixed to the flange with a fixing jig in a state where one main surface thereof is in contact with the reference surface of the flange, and the flange to which the thin blade grindstone is fixed is tapered. The one end face orthogonal to the axis of the rotating shaft is in close contact with the end face of the rotating shaft main body, and the inner peripheral surface of the tapered hole is attached to the rotating shaft in such a manner as to be in close contact with the outer peripheral surface of the tapered shaft portion. The thin blade grindstone can be securely fixed at a predetermined position via the flange, and the accuracy and reproducibility of the mounting position of the thin blade grindstone can be improved.

Before the thin blade whetstone can be mounted on the flange, adjust the thin blade whetstone to a state where there is no surface runout or eccentricity (radial runout) and there is little risk of chipping on the work before mounting it on the rotating shaft. By doing so, when the flange on which the thin blade whetstone is mounted is set on the rotating shaft of the machine tool, the processing can be performed immediately, and the processing efficiency can be improved.

が可能になる。Also, unlike the thin blade grindstone mounting structure of the present invention, a recess such as a clearance groove is not formed on the inner peripheral surface of the flange, and the tapered shaft portion of the rotating shaft is formed on the inner peripheral surface of the flange. When substantially the entire surface opposing the portion is in close contact with the tapered portion, since the rigidity in the radial direction is large, the mounting accuracy of the thin blade grindstone can be reliably maintained and the reliability can be improved. That is, the two-sided restraining structure in which one end surface of the flange is in close contact with the end surface of the rotary shaft main body, and substantially the entire inner peripheral surface of the tapered hole is in close contact with the outer peripheral surface of the tapered shaft portion, ensures that the flange is at a predetermined position. Since it is mounted, the thin blade grindstone held by the flange can be more reliably mounted on the rotating shaft without surface runout or eccentricity (radial runout).

ることができるようになる。In the thin blade grindstone mounting structure of the present invention, since the relief groove is formed at the boundary between the end face of the rotary shaft main body and the tapered shaft portion, the relief groove is formed in the tapered hole of the flange. Even if it is not necessary, it is possible to machine into a predetermined shape such that one end surface and the inner peripheral surface are in close contact with the end surface of the rotating shaft main body and the outer peripheral surface of the tapered shaft portion. (Particularly rigidity in the radial direction) can be improved, and the accuracy and reproducibility of the mounting position of the thin blade grindstone can be improved.

能になる。Further, the method of mounting the thin blade grindstone of the present invention is as follows.
Prior to mounting the thin blade whetstone to the rotating shaft, after performing the tooling by attaching the thin blade whetstone to the flange, the flange on which the thin blade whetstone is mounted, one end surface of which is in close contact with the end surface of the rotary shaft body, and Since the entire inner peripheral surface of the tapered hole is attached to the rotating shaft so as to be in close contact with the outer peripheral surface of the tapered shaft portion, the thin blade grindstone is subject to surface runout and eccentricity (radial runout) before being attached to the rotary shaft. No condition, that is, it is possible to easily adjust the work to a state in which chipping is less likely to occur, and it is possible to mount the thin blade grindstone at a predetermined position with good reproducibility, and the thin blade grindstone is mounted. When the flange is set on the rotary shaft of the machine tool, the machine can be machined immediately, and the operating rate of the machine tool can be improved.
