摘要：
A metal sheet working and/or pipe working machine (100) comprising a lightweight construction part (104) is provided, the lightweight construction part comprising a closed outer shell and framework in an interior of the closed outer shell, and a void volume enclosed by the outer shell. The void volume is filled by a gas different from air, especially a gas being lighter than air, for example Helium. The lightweight construction part may especially be a part that is moved and accelerated quickly during use of the machine.
