Product Overview
This custom long tubular housing is manufactured by turn‑mill composite machining, dedicated for RF & high‑frequency transformer assembly.
As typical thin‑wall aluminum cnc parts, this 296 mm hollow component requires strict geometry control against bending & spring‑back. Full CNC fabrication followed by 8 μm silver‑plating delivers superior electrical conductivity and electromagnetic shielding. All critical features are CMM inspected cnc components. We support prototype sampling and mass‑volume production with high precision cnc turning.
Suitable for OEM custom projects based on customer drawings, STEP / IGES 3D files.

H2‑CNC Machining Capabilities & Technical Highlights
Turn‑mill composite process: Complete outer contour, deep inner cavity and circumferential M6 threaded holes in minimal clamping times. Eliminate cumulative positioning error for tight GD&T requirements.
Anti‑deformation workflow for long thin‑wall structure: Rough machining → stress‑relief → finish turning. Solve bending & spring‑back risk for 296 mm hollow shell.
Strict hole‑position control for 16‑off M6‑H8 threads. Go‑no‑go thread gauge inspection, full deburring before electroplating.
All mechanical machining finished before silver plating. Machining dimension reserves plating allowance to prevent thread jamming after silver coating.
Full‑feature CMM inspection: Verify coaxiality, hole position, critical dimension and surface roughness. Inspection reports available upon request.Application

Q1: Is silver‑plating completed after CNC machining?
A: Yes. All CNC work is finished first, then silver‑plating 8 μm. No post‑plating machining.
Q2: What inspection reports can you provide?
A: CMM dimension report, roughness test report, plating thickness measurement report.
Q3: Can you produce according to non‑standard customer drawings?
A: Yes, we offer full OEM custom CNC service for aluminum mechanical housings.
