PROBLEM TO BE SOLVED: To provide a grinding attachment for miniaturizing the attachment, and efficiently grinding an object to be ground. SOLUTION: This grinding attachment 1 has a pair of grinding wheel 2 and 3 arranged so as to be freely rotatable around a prescribed rotary central shaft, and so that grinding action surfaces 2a and 3a orthogonal to the rotary central shaft are mutually opposed, a rotational driving mechanism rotating the respective grinding wheels 2 and 3, revolving arms 2 and 3 revolvably movably arranged around a revolving central shaft parallel to the rotary central shaft of the grinding wheels 2 and 3, the object holders 11 and 12 arranged on the respective obverse and reverse of the revolving arms 2 and 3, and holding the object W in a state of allowing a surface on the opposite side of a object surface to abut on receiving surfaces 13a and 14a parallel to the grinding action surfaces 2a and 3a, and revolving driving mechanisms 6 and 7 revolvably moving the revolving arms 2 and 3. The object W is ground, by passing through the inside of opposed spaces of the respective grinding wheels 2 and 3 by the revolving movement of the revolving arms 2 and 3. COPYRIGHT: (C)2005,JPO&NCIPI
