CNC Machining for Cryogenic and Ultra High Vacuum Applications
In the demanding fields of aerospace, semiconductor manufacturing, particle physics, and advanced scientific research, standard machined components are insufficient. Applications involving cryogenic temperatures, near absolute zero, or ultrahigh vacuum (UHV) environments, where pressures are billions of times below atmospheric, present unique engineering challenges. For these critical scenarios, specialized CNC machining is not just an advantage—it's an absolute necessity. Our company specializes in delivering precision CNC machined parts that meet the rigorous standards of these extreme conditions, ensuring performance, reliability, and vacuum integrity.

As temperatures plummet, most materials contract, which can lead to dimensional instability or failure if not accounted for in the design and machining phase. Similarly, in a UHV environment, any outgassing from the material itself or from microscopic surface imperfections can contaminate the vacuum, leading to system failure. Our expertise begins with material selection. We routinely work with lowoutgassing, highstability materials such as 300series stainless steels (particularly 304L and 316L), titanium alloys, and specific aluminum grades, all chosen for their minimal vapor pressure and predictable thermal contraction.
Beyond material choice, our CNC machining processes are meticulously tailored for these applications. We employ specific tool paths and cutting parameters to achieve exceptionally low surface roughness. A smoother finish minimizes the surface area where moisture and contaminants can adhere, significantly reducing outgassing once the part is placed under vacuum. Furthermore, we avoid creating sharp internal corners and deep, blind holes that can trap gases and are difficult to clean. All parts undergo specialized cleaning and passivation processes to remove all machining oils, fingerprints, and other hydrocarbons, which are primary sources of contamination.
Every component is machined with extreme precision to ensure perfect flatness for flange sealing and exact tolerances for thermal cycling. A poorly machined seal surface will leak, rendering a multimillion dollar UHV chamber or cryogenic system useless. Our commitment to precision ensures that our components integrate seamlessly and perform reliably from room temperature down to cryogenic levels and in the hardest vacuums.
