The present invention is implemented by: f4 respectively fixing a vertical plate and a support plate in perpendicular directions to each other by a semicircular chamfering angle WC adjustment plate at both sides of the head of the movable chamfering machine; fixing a vertical fixing plate on the outside of the ver4 tical plate such that a horizontal fixing plate is fixed on the front end of the vertical fixing plate so as to be perpendicular thereto; coupling a right side-opened square-shaped link to the vertical fixing plate such that an exterior roller coming into close contact with the outside of a pipe is provided to the front end of the right side-opened square-shaped link and the right side-opened square-shaped link is moved in the vertical direction by an exterior roller adjustment screw provided to the horizontal fixing plate; providing a movement body at the lower side of the horizontal fixing plate such that the movement body is moved in the vertical direction by an C interior roller adjustment screw provided to the horizontal fixing plate; and an interior roller, of which the compression force is ad justed by a spring and coming into close contact with the inside of the pipe, is provided to the movement body.
