These grindstones have excellent flexibility and elasticity, and have cushioning properties, so they conform well to the flat and curved surfaces of the object to be polished, allowing for an elegant finish. Moreover, when polishing glass with a non-flexible whetstone, there was a problem in the past that glass burns and scratches on the glass surface called so-called clams occurred, but the whetstone described in the above publication does not have such problems. The problem was almost solved.

In this grinder wheel, the support plate 1 rotates at high speed and the plate-like body 5 is strongly pressed against the object to be polished.
A strong pulling force is applied in the direction of . At this time, since the coarsely woven cloth 2 forms a rough surface of the support,
The fixation of the plate-shaped body to the support plate can be ensured. Even when the adhesive normally solidifies, it has more elasticity than other materials such as the support plate 1, and the base of each plate-like body 5 is embedded in the elastic layer 4 made of this adhesive. Therefore, the plate-like body 5
Even if a strong impact is applied to the material, this impact is alleviated by the elasticity of the elastic layer 4 made of adhesive.
As a result, it is possible to prevent each plate-shaped body 5 from slipping off to some extent. Furthermore, the concave lines and convex lines of the cloth 2 serve as a guide when planting the plate-like body 5, and
Since the elastic layers 3 and 4 made of adhesive are provided on the inner and outer surfaces of this cloth 2, when a strong pulling force is applied to the plate-like body 5, the grooves and protrusions are formed. The waveform formed by the plate member 5 is bent, and it is possible to more reliably prevent the plate member 5 from slipping out.
