Diamond horseshoe blocks are specialized tools for stone arc processing, composed of a steel substrate and a diamond abrasive layer. Leveraging the high hardness and wear resistance of diamonds, they can precisely grind stone edges into shapes like arcs and chamfers with high efficiency, resulting in smooth, burr-free cuts. Compatible with stone processing equipment, they are widely used in arc forming and refined processing scenarios such as stone curtain walls, countertops, and floor edges.
