摘要： A method and device for deburring, wherein a cutting blade is disposed so that its flank is roughly in parallel with the surface of a burred steel piece and an angle formed by the cutting edge of the cutting blade and the end part of the burred steel piece is 45° or larger and moved relatively so that it moves toward the outside of the steel piece along the longitudinal direction of burrs, or disposed so that its flank is roughly in parallel with the surface of the burred steel piece and an angle formed by the cutting edge of the cutting blade and the end part of the burred steel piece is 90° or smaller and moved relatively so that it crosses perpendicularly to the longitudinal direction of burrs so as to remove burrs from the end part of the steel piece, whereby burrs such as weld burrs formed in continuous rolling of billets can be cut off without burring.
