A structure for deburring a ball (200) is provided. The structure includes an arm (460), a gear structure (474) for changing the effective length of the arm, and a cam structure for changing the effective angular position of the arm. A finger (462) having an abrasive surface (466) reciprocates on the arm. A ball is placed in a rotating holder (310) and positioned in effective position for the abrasive surface to contact and remove at least one burr (201,222,228,248,250) on the ball.
