Abstract

A manufacturing method of the honeycomb structure uses a grinding wheel having a coarse abrasive grain layer and a pair of fine abrasive grain layers sintered and secured to be formed on both sides of the coarse abrasive grain layer, and has a grinding wheel rotating step of rotating the pair of grinding wheels disposed via a predetermined space in a state where fine abrasive grain layers of the grinding wheels face each other; a conveying step of conveying a honeycomb formed body formed by extrusion and the like; an end face grinding step of grinding end faces of the conveyed honeycomb formed body with the rotating grinding wheels; and a firing step of firing the honeycomb formed body.
