Metal embedded resin concave grinding wheel

The utility model provides a metal inlaid resin concave type grinding wheel which comprises a base body and a resin grinding layer, the resin grinding layer is arranged on the base body, the base body is an aluminum base with a concave chute step, the resin grinding layer comprises a resin binding agent and a metal binding agent which are mutually nested in a wave mode from outside to inside, and the metal binding agent is arranged between the resin binding agent and the metal binding agent. And the metal bonding agent is nested in the aluminum-based step. By means of the wave annular nested outer resin and inner metal structure, the technical problems that the grinding wheel is scrapped in advance and inner layer resin is wasted in vain due to the fact that an existing metal resin interlayer is combined with a step of the grinding wheel can be effectively solved, and the cost performance is high. 本申请提供了金属镶嵌树脂内凹型砂轮，包括基体和树脂磨削层，所述树脂磨削层设在所述基体上，所述基体为带内凹斜槽台阶的铝基，所述树脂磨削层包括由外到内相互波浪嵌套的树脂结合剂和金属结合剂，所述金属结合剂嵌套设在所述铝基台阶内。本申
