PURPOSE:To execute polishing in the wide range of the face to be worked with a sufficient polishing pressure being generated even the gap between a tool and the face to be worked being enlarged, by using a magnetic abrasive composed of a short fiber like magnetic body or this and a granular abrasive. CONSTITUTION:A magnetic polishing brush in the state of a short fiber like magnetic body 3a being raised between the face 21 to be worked of the body 2 to be worked and a tool 1, is formed, by using the short fiber like magnetic body 3a as a magnetic abrasive 3. Consequently, the magnetic attraction force effected on the face 21 to be worked of the head of this brush is improved and a sufficient polishing pressure is generated even in case of the gap between the tool 1 and the face 21 to be worked being enlarged. |
