Introduction

Precision Machining of Custom RF Shielding Enclosures

Precision Machining of Custom RF Shielding Enclosures

RF housings require strict control of cavity dimensions, flatness, and surface roughness to ensure proper shielding and signal performance. Thin walls, deep cavities, and tight coaxial alignment are common challenges in production.

At DEK, we apply 5-axis CNC milling to maintain consistency in cavity geometry and minimize tool deflection on thin-wall sections. Our process integrates roughing and finishing strategies to avoid chatter and distortion.

We validate each part with CMM, height gauge, and surface roughness tester, ensuring dimensional accuracy and repeatability. Our engineers also provide process simulation to optimize toolpath and avoid burrs that affect RF sealing.

High-Precision Cavity Milling for RF Enclosures

We apply 5-axis milling with optimized toolpaths for deep cavities and complex internal features. Tool deflection is compensated to ensure stable depth and surface uniformity.

Thin-Wall Structure Stability in RF Housings

Thin walls in RF housings require controlled cutting parameters and step-down strategies. We use customized fixturing and multi-stage machining to reduce deformation risk.

Surface Finishing for RF Shielding

After machining, surfaces are processed to Ra 0.8μm or better. Mirror polishing and anodizing are applied to enhance conductivity and corrosion resistance.

Threading and Port Accuracy

Connector ports and threaded features are machined using precision taps and gauges. Thread quality is verified with go/no-go gauges to ensure proper RF connection.

EDM for Sharp Corners

When housings require non-radiused internal corners, EDM machining ensures geometry without compromising cavity precision.

Full Dimensional Inspection on Every Lot

We use CMM, optical comparator, and runout gauges to verify critical cavity and connector dimensions. First Article Inspection (FAI) is conducted before full production.

RF-Specific Material Certification

Each aluminum or copper lot is verified with spectrometer analysis. Certified reports are provided for conductivity and alloy compliance.

Controlled Packaging for Precision Surfaces

To avoid scratches and particle contamination, housings are vacuum-packed or cushioned in anti-static trays. Large units are secured in fumigation-free wooden crates.
