Core Component of Mass Spectrometer: Vacuum Interface Chamber

Material of the vacuum interface chamber

High-quality 6061-T6 aluminum alloy is selected. It has the advantages of both high strength and light weight, with high tensile strength, which can ensure structural stability under complex working conditions. Meanwhile, it has good corrosion resistance, suitable for various industrial environments such as scientific research experiments and electronic manufacturing, meeting the strict performance requirements of vacuum systems for materials.

• Material preparation: Milling the outline to the specified size with a square ruler;
• Heat treatment: Aging twice, with the temperature not exceeding 220 degrees and the time controlled within 4 hours to eliminate internal stress of the material;
• 5-axis machining: Rough cutting with a allowance of about 1.5mm, followed by finish milling to form, completing processes such as drilling holes, grooves, tapping threaded holes, and chamfering, with strict control over form and position tolerances and dimensional tolerances;
• Fitter processing: Tapping, deburring, and polishing the surface according to mass spectrometry requirements to avoid scratches;
• Surface treatment: Conducting natural color conductive oxidation to ensure uniform color and no color difference;
• Subsequent processes: Installing wire thread inserts, and finally delivering after ultrasonic cleaning (according to mass spectrometry cleaning process), inspection, and packaging.

Precision machining requirements for the vacuum interface chamber

• Dimensions and tolerances: Strictly control dimensional tolerances and form and position tolerances, and the roughness must meet the requirements of the drawings (for example, the surface with a roughness of 1.6 is not allowed to be polished manually and must be formed by milling);
• Detail processing: Details such as threads and chamfers must be refined, and the surface must not be scratched during tapping and deburring;
• Surface quality: Natural color conductive oxidation must have uniform color and no color difference to improve wear resistance and corrosion resistance;
• Quality control links: Each process requires first inspection and in-process inspection, and for batch parts, inspection records must be filled in according to standards to ensure product qualification.

As a core component of the mass spectrometer, its main role is to provide a key connection for the vacuum system. Through its precise interface structure, it ensures the stable construction and maintenance of the vacuum environment, realizing vacuum connection and transmission functions under harsh working conditions. It is a core precision component for the equipment to achieve vacuum functions, which can reduce the risk of system operation failures and help improve the reliability and efficiency of the entire mass spectrometer.
