This paper deals with the development of a porous melamine bond wheel which is suitable for pressure-controlled grinding on die materials. Carbon dioxide, which is generated by the chemical reaction between sodium acid carbonate (SAC) and sodium acid pyrophosphate (SAP), was applied to generate an open cellular structure by mixing the above forming chemicals within the resin. Performance of wheels which show various formed structures was examined through the measurement of grinding force, removal rate and wheel wear rate under the process of surface grinding on the sintered tungsten carbide. It became clear that the pore size and pore structure could be controlled by varying the composition of the chemicals used and composition ratio of SAP in the chemical mixture. Also, it was confirmed that self-dressing of the wheel was activated proportionally as the pore structure changed from a closed cell to an open one and pore size became large.
