ABSTRACT:
A chip removing device for removing foreign matter such as chips from a groove defined circumferentially on an inner peripheral surface of a cylindrical workpiece, which includes a blowhead that is fittable into the cylindrical workpiece, a shaft for supporting the blowhead and a motor for rotating the blowhead and a motor for rotating the blowhead. A movable member having a scraper defined on one end thereof is mounted for movement within the blowhead and has a passage defined therein for supplying compressed air to a nozzle adjacent to the scraper. In operation, the blowhead is inserted into an interior cavity of a workpiece, the movable member is extended outwardly and the blowhead is rotated to cause the scraper to remove foreign matter from a groove that is defined in a inner peripheral surface of the workpiece, while compressed air is simultaneously applied to help loosen the foreign matter.
