A manufacturing method of the foaming-type grinding wheel with big air pores includes the steps that the resin adhesive and the thinner are added into a container to be evenly stirred under the water bath condition of 60 DEG C; then the abrasive material and the surface active agent are added to be evenly stirred; afterwards, the secondary reinforced resin, the dextrin, the starch, the filler, the foaming agent and the defoaming agent are added in sequence, and slurry is injected into a mold of 45-60 DEG C when the reaction temperature of the slurry reaches 50 DEG C; and finally the mold is put into an oven to be roasted, demolding is conducted after the slurry in the mold is completely cured, and accordingly the foaming-type grinding wheel with big air pores can be obtained. The foaming-type grinding wheel with big air pores has the characteristics that the grinding wheel is low in weight and nontoxic, and air pores are uniform; the grinding wheel is far superior to a common resin grinding wheel on the aspects of water resistance, abrasion resistance, heat-conducting property and the like; and especially when the grinding wheel is used for grinding long-axis metal parts, no vibration ripple can be caused, and the grinding effect is better.
