取付けてなるバーリング加工用カム型。 A first die in contact with the first wall of a workpiece having parallel first and second walls is fixed to a base, and burring is performed on the first wall in cooperation with the first die. A punch having a large-diameter machining section for performing machining is fixed to a first slide cam that is horizontally slidably installed on the base, and a movable spacer that contacts the second wall is attached to the second slide cam. A second punch is installed on the base so as to be movable toward and away from the wall, and performs burring on the second wall by cooperating with a small-diameter machining section formed at the tip of the large-diameter machining section of the punch. A second die is provided on a second slide cam installed on the base so as to be slidable in the same direction as the horizontal direction, and a backup putty fitted between the first die and the movable spacer is provided in the horizontal direction. a first drive cam that is installed on the base to be slidable in a horizontal direction perpendicular to the direction and that drives the first slide cam; and a second drive cam that drives the second slide cam; A burring cam type in which a third drive cam for driving the back-up plate is attached to an upper holder provided above the base so as to be movable up and down.
