Centrifuge

A centrifuge is a device that spins something causing artificial gravity.  A washing machine  is a centrifuge, as is a clothes drier.  A centrifuge is also used in the manufacture of nuclear material. ("The Nuclear Jihadist: page 11)

A steel known as maraging steel seems to be needed for making centrifuges for enriching uranium. ("The Nuclear Jihadist: page 43)
