Abstract

There is disclosed a manufacturing method of a honeycomb structure in which a cutting step of a honeycomb formed body (20) in finishing steps can be omitted or replaced, and end faces of the honeycomb formed body (20) can be finished only by an end face grinding step. A manufacturing method of the honeycomb structure (20) uses grinding wheels (10) having a coarse abrasive grain layer (13) and a pair of fine abrasive grain layers (11 a, 11b) sintered and secured to be formed on both sides of the coarse abrasive grain layer (13), and has a grinding wheel rotating step of rotating the pair of grinding wheels (10) disposed via a predetermined space in a state where fine abrasive grain layers (11a) of the grinding wheels (10) face each other, in a predetermined rotating direction (R) around a rotation axis (D); a conveying step of conveying a honeycomb formed body (20) formed by extrusion and the like, to the space between the pair of grinding wheels (10) along a conveying direction (C) orthogonal to a central axis direction (B) of the honeycomb formed body (20); an end face grinding step of grinding end faces (21a, 21b) of the conveyed honeycomb formed body (20) with the rotating grinding wheels (10); and a firing step of firing the honeycomb formed body (20).
