        The special polymer solid boron carbide abrasive is made by mixing other materials into the main material. The thickness of the abrasive is related to the roughness of the surface of the workpiece according to the surface roughness of the workpiece. The abrasive has sharp cutting property and self-sharpness.It does not chemically react with many non-metal (glass, ceramic) and certain metals (zinc, steel and its alloys). It is suitable for processing glass, ceramics, stone, cast iron and some non-metal, hard alloy, high-speed steel, etc.
