Claims

[Scope of utility model registration request]

A grindstone holder that is attached to the rotating shaft of a machine tool and used for polishing curved surfaces, has a large-diameter flange that has a mounting shaft fixed to the rotating shaft on one side and a holding shaft on the other side concentrically, and the holding shaft of the holder. A whetstone, which is fitted with a required clearance to the whetstone, is restrained from moving and rotating in the axial direction, and is held by being applied with a substantially uniform biasing force in the radial direction from a holding shaft. holder.
