ABSTRACT:
A machine for mechanically treating components, such as metallic hollow members having a body and a bottom. The machine has a stationary frame bearing a plurality of work stations each of which has a tool pair including a first fixed tool coaxial with a movable second tool. The first and second tools are arranged on two coaxial circular paths with the first tool of each pair on a bolster. The second tool of each pair is on one end of a ram member having a tool bearing end and an actuated end. The ram member is slidably supported in guiding means. The actuated end of the ram member is connected to a cylindrical actuating cam having a free end in contact with the actuated ram member end. At least one pair of the tools are different than another pair. The tool bolster is immovable, the cam is rotated and transfer mechanisms are associated with the machine so that each component is treated by at least two different pairs of tools.
