Grinding wheel for machining microbit

The utility model relates to the technical field of grinding wheels, in particular to a grinding wheel for machining a microbit. Comprising a base body, a green silicon carbide layer and a carborundum layer are sequentially arranged in the thickness direction of the base body, the green silicon carbide layer and the carborundum layer are provided with a grinding face, and the included angle between the grinding face of the green silicon carbide layer and a center shaft is 15 degrees. And the processing efficiency can be improved. 本实用新型涉及砂轮技术领域，尤指一种用于加工微型钻头的砂轮。包括基体，沿基体厚度方向依次设有绿碳化硅层和金刚砂层，绿碳化硅层和金刚砂层上设有摩削面，绿碳化硅层摩削面与中心轴之间的夹角为15°，通过在基体上设置金刚砂层和绿碳化硅层，既能保证微型钻头整体的圆跳动和同轴度，又能提高加工效率。
