Precision Machining of Custom Metal C-Rings

Precision CNC machining services are required for the production of seven unique types of Parker C-rings designed to function as hermetic seals within the DAVINCI Venus Mass Spectrometer instrument, a key component of NASA’s mission to explore Venus. These components demand exacting tolerances and material integrity to ensure reliable performance in the extreme environmental conditions of space and planetary atmospheres, with manufacturing taking place under strict quality control standards aligned with defense and aerospace specifications. The work is part of a subcontract under the NASA Shared Services Center, with performance localized in Greenbelt, Maryland, where the finished parts will support critical scientific instrumentation. The opportunity is posted under NAICS code 332710, indicating a focus on machined metal products, and requires response submissions by June 17, 2026, at 12:00 PM, with a solicitation posted on June 15, 2026. This is not a set-aside contract, meaning all eligible contractors may compete, and the work is expected to adhere to the high standards of reliability and traceability essential for NASA scientific missions. The successful vendor must demonstrate proven capability in high-precision machining of small, complex metal components and have experience with spaceflight hardware or similarly regulated environments, ensuring the C-rings meet or exceed the functional and environmental requirements of the VMS instrument.
