Custom CNC Machined Vacuum Flange

Product Overview

As a professional CNC machining manufacturer with 26 years of OEM&ODM experience and ISO 9001, ISO 14001, IATF 16949, ISO 13485 multi-system certification, Dawang Precision specializes in producing Custom CNC Machined Vacuum Flange solutions for industrial and enterprise customers worldwide. This high-accuracy adapter component is machined with industry-leading 5-axis CNC technology, crafted from premium 6061-T6 or 7075-T6 aluminum alloy, and designed with a central raised sealing ring and precision threaded hole pattern to deliver leak-tight performance and stable alignment in critical systems. With strict ±0.01mm tolerance control and optimized flatness via mirror polish finish, our precision aluminum vacuum flange ensures minimal distortion and reliable long-term operation for demanding precision applications. We accept full customizations based on your drawings, samples, or specific design requirements, with free quotations provided within 24 hours.

Dawang Precision produces custom CNC machined vacuum flanges and optical adapter plates in aluminum alloy. This component features a central raised ring and precision hole pattern for reliable sealing and alignment—ideal for vacuum systems, optical instruments, and precision equipment requiring leak-tight connections and minimal distortion.

Machined with 5-axis CNC technology for exceptional flatness and tight tolerances.

Features & Benefits

Leak-Tight Sealing for Critical Vacuum Environments

The integrated central raised ring of our 5-axis CNC machined vacuum flange is precision-engineered for O-ring sealing, paired with high-precision threaded holes to create a fully leak-tight connection. This design eliminates vacuum loss risks, ensuring stable pressure maintenance for high-vacuum systems, a core priority for industrial and laboratory enterprise customers.

Ultra-Precision Machining for Unmatched Alignment Stability

With a tight ±0.01mm tolerance and mirror-polished flat surface, our mirror polished vacuum flange delivers exceptional mounting stability and precise alignment. This minimizes installation deviation and optical path distortion, making it ideal for high-accuracy optical and precision instrument integration.

Lightweight High-Strength Aluminum Construction

Crafted from aerospace-grade 6061/7075 aluminum alloy, our vacuum system connector flange combines superior structural strength with lightweight performance. This reduces overall equipment weight, simplifies installation and maintenance, while maintaining excellent corrosion resistance and long-term durability.

Full Customization for Tailored System Integration

We offer fully customizable design for our custom CNC flange plate, including dimensions (diameter range 100-150mm), hole patterns, surface finishes (mirror polish or anodizing), and port configurations, to perfectly match your specific vacuum or optical system standards.
