Abstract
An arrangement for working a tube end includes: an operating cylinder with a piston displaceable along an longitudinal axis; and a tube mounting, a tool holder being provided at an end of the piston facing the tube mounting. The operating cylinder is provided as a tandem cylinder. At least two cylinder stages are offset along the longitudinal axis. The piston includes connected piston segments, each piston segment being allocated to a cylinder stage.

An arrangement for working a tube end, the arrangement comprising:
- an operating cylinder with a piston displaceable along a longitudinal axis;
- and
- a tube mounting, a tool holder being provided at an end of the piston facing the tube mounting,
- wherein the operating cylinder is a tandem cylinder,
- wherein at least two cylinder stages are offset along the longitudinal axis,
- wherein the piston comprises connected piston segments, each piston segment being allocated to a corresponding cylinder stage,
- wherein a tool is attached concentrically to the tool holder so as to be co-axial with the tool holder along the longitudinal axis and
- wherein the tool comprises an operating axis which is radially offset with respect to the longitudinal axis.
