Abstract
The cutting method of a honeycomb formed body includes an end face cutting step of cutting both end faces of the ceramic honeycomb formed body before fired, by use of blade type rough-cutting grinding wheels in which coarse abrasive grain layers are formed; a honeycomb formed body rotating step of rotating the honeycomb formed body round a rotation axis which is a central axis perpendicular to the end faces of the honeycomb formed body; and an end face finishing step of disposing two finish-polishing grinding wheels via a predetermined distance so that finishing abrasive grain layers formed in the finish-polishing grinding wheels face each other, rotating the finish-polishing grinding wheels round a rotary shaft which is a central shaft of the finish-polishing grinding wheels, and moving the honeycomb formed body to pass the honeycomb formed body between the two finish-polishing grinding wheels, thereby finish-polishing cut surfaces which are cut.
