ABSTRACT:
The flame-cut sheet metal elements to be deburred have a surface which lies substantially in a plane and have edge portions which are formed with sharp-edged metallic burrs extending generally in said plane and carry slag beads which protrude from said surface. Tool means are caused to perform a gyratory motion parallel to said plane and while performing said motion are engaged with said slag beads to break them off. Said tool means are caused to engage also said metallic burrs while performing a gyratory motion parallel to said plane, whereby said burrs are impact-deformed.
