    • PURPOSE:To stably obtain an abrasive grain reamer with a highly accurate outer diameter dimension, by press-fitting a sleeve to an axial member again until the outer diameter of the abrasive grain layer becomes an estimated value, after executing the outer diameter dressing on the abrasive grain layer. CONSTITUTION:A sleeve 2 and an axial member 1 are first engaged with the pressure fitting via taper faces 1b, 2a each other. Then, an abrasive grain layer 6 is formed by coating the abrasive grain with the electrodeposition on the specific part of the outer peripheral face 2b of the sleeve 2. Moreover, the outer diameter dressing is executed on this abrasive grain layer 6 and after smoothing the surface thereof, the sleeve 2 is re-press-fitted to the axial member 1 until the outer diameter of the abrasive grain layer 6 of this sleeve 2 becomes at the specific value and an abrasive grain reamer 7 of a high dimensional accuracy is stably obtained.
