More Information
Summary:The invention relates to a high-accuracy composite type grinding crankshaft grinding wheel which has three layers of an upper layer, a middle layer and a lower layer. The high-accuracy composite type grinding crankshaft grinding wheel is characterized in that an abrasive at the upper layer of the grinding wheel is rubing grain (PA), an abrasive at the middle layer of the grinding wheel is white alundum (WA), and an abrasive at the lower layer of the grinding wheel is rubing grain (PA); the grinding wheel also comprises a special ceramic bond, wherein the ceramic bond comprises the following chemical components: 17-23% of Al2O3, 50-55% of SiO2, 4-8% of K2O, 4-8% of Na2O, less than 1% of MgO, less than 1% of CaO, less than 1% of Fe2O3, less than 1% of TiO2 and 8-13% of B2O3. The invention meets the requirements of users, can replace the imported grinding wheels with the similar type, saves the merchandise purchase time of users, also lowers the cost and saves the foreign exchange for China.
