Aiming at the problems of low efficiency and cumbersome processes in the processing of granite, marble, concrete and other stones, a well-known stone tool R&D enterprise has launched a new type of diamond double row cup wheel for concrete, stone and marble grinding. This diamond grinding cup wheel for granite and stone is designed with double rows of diamond tool heads, integrating rough grinding, fine grinding, and polishing functions. It can be adapted to universal angle grinders, eliminating the need for frequent replacement of grinding tools in traditional stone processing. By optimizing the material ratio of the tool head, the product effectively reduces the scratch rate on the stone surface during the grinding process and improves the processing precision. It is understood that after pilot applications in multiple large-scale stone processing bases, the product has been highly recognized by enterprises for its efficient and stable performance. Industry analysts pointed out that the launch of this double row diamond grinding cup wheel will promote the transformation of the stone processing industry towards high efficiency, energy saving and refinement.
