PURPOSE: To provide a dry-machining method and a grinding wheel for dry- machining, capable of dry-machine of a ceramic molded body such as a β-alumina pipe while suppressing blinding.

CONSTITUTION: A compressed air supply chamber 9 is formed inside a grinding wheel, and abrasive grain in the grinding face of the grinding wheel is bound by communicating porous binding material to form a porous grinding wheel 10. During grinding, air blow is performed constantly from the inside of the grinding wheel so as to enable the suppression of blinding of the grinding wheel.
