Zusammenfassung:PROBLEM TO BE SOLVED: To provide a mechanism tube expanding machine capable of reducing wear of relatively moving faces against each other and eliminating a lubricant oil use in these regions. SOLUTION: The mechanical tube expanding machine has a pyramidal polygonal body 2 and segments 3 provided with side faces of the polygonal body, the segments are radially moved by relatively sliding the polygonal body 2 for the segments 3, in the axial direction wear films 5 are arranged between the side faces of the polygonal body 2 and the segments 3.
