Precision 6060 Large Valve Body with 5-Axis Milling and RAL 7035 Anodized Finish

We manufactured a large 6060 aluminum valve body (AVP01-ISOK160-LMDA-01) for an industrial vacuum equipment application. This large-scale component requires complex internal geometry with smooth surfaces essential for vacuum sealing integrity — a requirement that conventional 3-axis machining cannot reliably achieve due to the part's size and geometric complexity. Large valve bodies with tight sealing requirements benefit significantly from 5-axis machining, which provides three key advantages: single-setup machining eliminates repositioning errors, continuous optimized toolpaths maintain ideal cutting angles for superior surface finish even in contoured areas, and reduced cumulative tolerance stacking ensures higher overall accuracy across the large geometry [citation:6]. Through 5-axis milling, we achieved the required internal surface finish for vacuum sealing while maintaining the part's structural integrity.

Project Overview

Key Technical Highlights

• 5-Axis Milling for Vacuum-Grade Surfaces: The large valve body geometry — complex internal contours and deep cavities — demands 5-axis machining to achieve the smooth internal surfaces required for vacuum sealing. Five-axis capability enables single-setup machining of complex geometries, eliminating the repositioning errors that compromise internal surface integrity [citation:6][citation:7].
• RAL 7035 Anodized Finish: Full-component anodizing in RAL 7035 light gray provides uniform corrosion protection and consistent aesthetic appearance. This finish is particularly valued in industrial vacuum equipment for its professional appearance and resistance to environmental exposure.
• Vacuum Sealing Surface Control: Internal surfaces that contact the vacuum environment are precision-finished to eliminate defects, tool marks, and irregularities — ensuring the sealing integrity required for vacuum applications [citation:1].

Quality Verification

CMM inspection verified dimensional accuracy and internal surface geometry. Internal surfaces inspected for smoothness and defect-free condition. Anodized coating verified for color consistency and coverage per RAL 7035 specification.

Industry Applications

Ideal for industrial vacuum equipment valve bodies, large-scale fluid control components, vacuum chamber hardware, and OEM valve assemblies.
