PROBLEM TO BE SOLVED: To control rotating velocity of a barrel tank with high precision so as not deviate from a target value.SOLUTION: A centrifugal barrel polishing machine includes: a turret 11 which is rotationally driven by a motor 14 for revolution; a solar rotor 19 which is concentrically relatively rotatable with respect to the turret 11; a motor 20 for rotation which can rotate the solar rotor 19; a barrel tank 12 which is rotatably disposed in an eccentric position of the turret 11 and rotates in a planetary manner in conjunction with the relatively rotating solar motor 19; a sensor 30A for revolution which measures rotational speed of the turret 11; and motor controlling means 33 which controls driving velocity of the motor 20 for rotation on the basis of the measured value of the sensor 30A for revolution and a set rotating velocity target value of the barrel tank 12. |
