The present invention relates to a movable grinding tool and a resin grinding stone. The movable grinding tool has a structure of vertically moving not to damage or cut the surface of a concave mold. The movable grinding tool has a weight control block to add a proper weight for use so that a grinding work on the surface can be smoothly performed. A resin solution in which the powder-formed grinding stone is added into a soft synthetic resin and is molten is integrated with a resin combining unit to prevent the size of a mold from being changed due to excessive cutting on the surface of the mold to be ground. So, the movable grinding tool can obtain a beautiful surface and can prevent a part of the mold from being damaged. The movable grinding tool is also easily operated by operation of a program in a grinding device. |
