Sweat gland structure endocrine-imitated cooling sintered grinding wheel and preparation method thereof

The invention discloses a sweat gland structure endocrine-imitated cooling sintered grinding wheel and a preparation method thereof. The grinding wheel comprises a grinding wheel body, a grinding wheel center hole is formed in the center of the grinding wheel body, grinding wheel abrasive particles are fixedly arranged on the outer wall of the grinding wheel body, and multiple of first-stage mainholes extending outwards with the grinding wheel center hole as the axis are formed in the grinding wheel body. The method is characterized in that a net-shaped pipeline is placed in a grinding wheelmanufacturing pressing mold in advance, and the net-shaped pipeline is made of materials which are melted and volatilized when meeting high temperature; and the materials for manufacturing the grinding wheel are melted and mixed, and then injected into a mold for rolling molding. According to the grinding wheel and the preparation method, cooling lubricating films matched with the grinding condition are continuously obtain
