Items:
a. Rotor assembly equipment for assembly of gas centrifuge rotor tube sections, baffles, and end-caps;
Note:
2B228.a includes precision mandrels, clamps, and shrink fit machines.
b. Rotor straightening equipment for alignment of gas centrifuge rotor tube sections to a common axis;
Technical Note:
The rotor straightening equipment in 2B228.b normally consists of precision measuring probes linked to a computer that subsequently controls the action of, for example, pneumatic rams used for aligning the rotor tube sections.
c. Bellows-forming mandrels and dies for producing single-convolution bellows.
Technical Note:
In 2B228.c, the bellows have all of the following characteristics:
1. Inside diameter between 75 mm and 650 mm;
2. Length equal to or greater than 12.7 mm;
3. Single convolution depth greater than 2 mm; and 4. Made of high-strength aluminum alloys, maraging steel or high strength “fibrous or filamentary materials”.
