Abstract
A method for manufacturing a porous metal bonded grindstone with which it is possible to arbitrarily adjust a porosity from a low porosity to a high porosity is provided. This method is intended for manufacturing the porous metal bonded grindstone and comprises: a molding step (P1) for obtaining an unfired molded body including abrasive grains, metal powder, and a pore forming material; a solute removing step (P2) for bringing vapor of a solvent having solubility with respect to the pore forming material into contact with the unfired molded body to remove the pore forming material and to obtain an unfired molded body having pores; and a firing step (P3) for firing the unfired molded body having pores.
