In centerless grinding, unbalanced parts are hard to get precise accuracy, because the centrifugal force caused by rotating the unbalanced mass tends to move the part up and down, and/or fall down the part from work support blade. The unbalanced parts are classified into 3 types by the position of unbalanced mass. The first report presents the criteria of this movement of each type of the unbalanced part by analyzing the balance of the forces working on it. This paper deals the experiment of centerless grinding of those 3 types unbalanced parts. The experimental results indicate that the accuracy was not affected substancially by the unbalanced mass under the stable grinding conditions, and this is coinsident with analytical results.
