In a method of producing a honeycomb structure molding die composed of feed holes through which molding material is fed and slit grooves communicated with the feed holes for the use of molding a honeycomb structure body, the slit grooves are formed on one surface of a metal material in a lattice arrangement by repeatedly moving a thin circular grindstone blade which is rotating in a straight-line direction or a line direction approximating a straight line in order to cut the surface of the metal material. In particular, the method removes fine metal powder, generated by cutting the surface of the metal material, using polishing grooves formed in a dressing grindstone disposed in front of the metal material every cutting of the metal material during the slit groove formation. |
