Beschreibung
Zusammenfassung:	The present invention comprises a turntable which holds a turbine part at a predetermined position, the turn table being rotatably supported by a support member, and rotated and driven by a driving motor, an abrasive feeding unit which feeds an abrasive particle having an elastic material as a core to a predetermined position as an abrasive, and a polishing head including an impeller which is rotated and driven by an impeller driving motor at high speed and applies rotary energy to the abrasive particle to be supplied from the abrasive feeding unit, the polishing head injecting the abrasive particle flying from the tangential direction of the impeller at a predetermined speed toward a surface to be polished of the turbine part held on the turntable, and an abrasive recovery unit which recovers the abrasive particle provided for polishing of the turbine part from the polishing head, and feeding into the abrasive feeding unit.
