In the demanding fields of semiconductor manufacturing, aerospace, scientific research, and particle physics, vacuum systems are the backbone of innovation. The performance and reliability of these systems are critically dependent on the precision and integrity of their internal components. This is where specialized CNC (Computer Numerical Control) machining becomes indispensable, transforming highperformance materials into the flawless parts that vacuum environments demand.

Why Precision CNC Machining is NonNegotiable

Vacuum system components, such as chambers, flanges, feedthroughs, and manipulators, must adhere to uncompromising standards. The primary challenges are:

UltraHigh Vacuum (UHV) Integrity: The slightest surface imperfection, microfissure, or inappropriate porosity can trap gases and compromise the vacuum level. CNC machining achieves the necessary surface finishes and dimensional tolerances to minimize outgassing and ensure a perfect seal.
Material Compatibility: Components are often machined from specialized materials like 304 or 316 stainless steel for its low outgassing properties, aluminum for its high conductivity and light weight, and titanium for its strengthtoweight ratio and corrosion resistance. Advanced CNC machines are expertly configured to handle these tough materials without introducing contaminants.
Complex Geometries: Vacuum systems often require intricate parts with precise grooves for Orings (e.g., CF flanges), threaded ports for attachments, and internal cooling channels. 5axis CNC machining provides the capability to produce these complex shapes from a solid block of material, eliminating potential leak paths from welded assemblies.

Our Expertise as Your Strategic Manufacturing Partner

Our company provides a comprehensive, onestop solution for your vacuum component needs. We understand that your projects require more than just cutting metal; they require a deep understanding of the application.



FullService Machining: From initial material selection and CAD/CAM programming to precision machining, finishing, and quality control, we manage the entire process. We offer a range of finishing options, including electropolishing and passivation, which are critical for creating a smooth, passive surface that resists corrosion and minimizes surface area for gas adsorption.
Rigorous Quality Assurance: Every component is subject to stringent inspection using CMM (Coordinate Measuring Machine) and surface profilometry to verify it meets all specified tolerances and finish requirements (often achieving 32 µin Ra or better). For critical parts, we can coordinate with certified thirdparty labs for helium leak testing to guarantee UHV integrity.
Driving Your Growth: By outsourcing to us, you reduce lead times, mitigate supply chain risks, and gain access to expert engineering support. This allows you to focus on your core R&D and system assembly, accelerating your timetomarket for nextgeneration equipment.

In an industry where precision is paramount, partnering with a CNC machining expert dedicated to vacuum applications is a strategic advantage. Let us help you build the reliable, highperformance systems that power tomorrow's discoveries.
