PROBLEM TO BE SOLVED: To provide a burring machine capable of removing burrs produced on the rim around the circumference and in a punched part without damaging a surface and rounding the edge of a thickness part. SOLUTION: A means of energizing 13 presses a deburring file 15 on a cone sharpened toward its top against a work W hung from a work hanging machine 3, and if the deburring file is moved right and left relatively to the work by a movement mechanism 21, the deburring file 15 enters into a hole bored in the work, comes out of it and moves up and down along the outline, in order to remove burrs produced in the hole and on the outline. At this time, since a roller is provided at the tip of the deburring file 15, and it moves while pressing the lower surface of the work and enters in a hole by rising if there is one there, the surface of the work is prevented from being damaged.
