Abstract

PURPOSE: To enable interior wall surface of a tubing to be ground satisfactorily and efficiently, without turning the work, by making a grinding head rotate on its own axis and turn around the interior wall surface at the same time.
CONSTITUTION: By driving of a grinding head turning motor 4, a gear b is turned through a reduction gears 5, 6. By this turning a frame 16 is also turned through a flange 19. At this time, a travelling roller 22 and a grinding head 18 are pressed against an inner diameter surface 2 of a turbine rotor 1 by a spring 30. As the aforementioned travelling roller 22 is in contact with the inner diameter surface 22 at an inclination of a given angle, when a grinding unit 15 turns around, the travelling roller 22 is moved forwardly and backwardly in accordance with the turning direction. With turning around of the grinding unit, the grinding head 18 is also rotated on its own acis through a rotation driving motor 4 so that the interior wall surface 2 of the turbine rotor 1 is ground by the grinding head 18.
