Guangzhou Mingguan Intelligent Manufacturing Technology Co., Ltd.
MGZZ CNC is a precision machining supplier focused on RF, microwave, and millimeter-wave components.
We support engineers developing waveguides, antenna arrays, RF shielding enclosures, and microwave cavities requiring tight tolerance and high surface quality.
Unlike general CNC factories, we understand how machining quality affects RF performance.
Surface roughness, dimensional deviation, and assembly alignment directly impact insertion loss and signal stability at high frequencies.
Our capabilities include:
• 5-axis CNC machining
• Waveguide cavity machining
• Surface roughness control
• Conductive anodizing
• RF component assembly

Why Machining Quality Matters in RF Components?
At microwave and millimeter-wave frequencies:
• Surface roughness increases insertion loss
• Dimensional error shifts operating frequency
• Poor assembly alignment causes signal leakage
Precision machining is critical for RF performance — not just mechanical fit.

FAQ
Millimeter-wave components typically require tolerances between ±0.01 mm and ±0.005 mm depending on operating frequency.
Surface roughness affects insertion loss and signal transmission efficiency at microwave frequencies.
Aluminum 6061-T6 and 7075 are commonly used for RF and millimeter-wave components because of their machinability, lightweight properties, and good electrical performance. Copper and brass are also used for waveguide and microwave cavity applications requiring higher conductivity.
5-axis CNC machining allows complex waveguide geometries and deep cavities to be machined with fewer setups, improving alignment accuracy and reducing dimensional deviation that may affect RF performance.
RF waveguide components typically require surface roughness between Ra 0.8 and Ra 0.4 depending on frequency range and insertion loss requirements. Smoother internal surfaces help reduce RF signal loss at high frequencies.
Machining tolerance directly affects microwave and millimeter-wave performance. Dimensional deviation may shift operating frequency, increase insertion loss, or affect signal stability in high-frequency systems.
Yes. Conductive anodizing is commonly used for aluminum RF enclosures and microwave components because it provides corrosion resistance while maintaining electrical conductivity for grounding and shielding applications.
Common challenges include maintaining tight tolerance in deep cavities, achieving low surface roughness, controlling assembly alignment, and minimizing deformation in thin-wall structures.
We accept STEP, STP, IGES, Parasolid, and PDF drawings for RF and precision CNC machining projects. 3D CAD files are recommended for DFM review and tolerance evaluation.
RF and microwave components are inspected using CMM measurement, surface roughness testing, and dimensional verification to ensure tolerance and surface quality meet engineering requirements.
