Abstract: There is disclosed a grinding method of a honeycomb structure, wherein a grind processing member having an outer peripheral surface, a first grinding wheel tapered surface and a second grinding wheel tapered surface and rotating around a central axis grinds a joined honeycomb segment assembly rotating around a central axis, and the above respective surfaces of the grind processing member form a first ground region, a second ground region, a center ground surface, a first tapered surface and a second tapered surface, to prepare the honeycomb structure including a cylindrical honeycomb base material, and a ring-like bulge portion “which surrounds an outer periphery of the honeycomb base material, protrudes from the outer periphery of the honeycomb base material toward the outside in a flange manner, and has the first tapered surface, the second tapered surface and the center ground surface.”

Abstract: An inspection method for a pillar-shaped honeycomb filter having a honeycomb-shaped first end face and a honeycomb-shaped second end face, including: allowing gas containing fine particles to flow into the first end face; imaging the entire second end face covered with the sheet-like light using a camera while the gas that has flowed into the first end face flows out of the second end face through the filter, and generating an image of the entire second end face covered with the sheet-like light; selecting an inspection area of the second end face and measuring information concerning a sum of luminance of each pixel in the inspection area; and determining quality of the filter based on at least the information concerning the concentration of the fine particles in the gas before the gas flows into the first end face and the information concerning the sum of luminance.
