Custom CNC Turned Copper Flange Bushings

FlexiTurn provides precision CNC turning services for custom copper flange bushings, delivering dimensionally consistent shoulder-type sleeves engineered for electrical conduction, thermal transfer and precision locating applications.

Single-Setup Turning & Precision Secondary Operations

This flanged copper bushing demands strict bore-to-OD concentricity, controlled surface finish and accurate flange shoulder geometry to ensure reliable press-fit assembly and consistent performance in power distribution and signal connection systems.

We manufacture these components from high-purity ETP copper bar stock on dedicated CNC turning centers, completing all rotational features – internal bore, outer diameter, flange shoulder and end chamfers – in a single chucking setup to eliminate runout error and maintain strict concentricity.

Our machining parameters are calibrated specifically for copper materials to control tool wear, surface scratching and dimensional drift, delivering repeatable accuracy across every production batch. For applications requiring enhanced precision or surface performance, we offer secondary operations including precision ID/OD grinding, edge deburring and electroplating (tin, silver, nickel) to meet specific functional requirements.

Material Portfolio & Engineering DFM Optimization

Beyond pure copper grades, our CNC turning capabilities cover a full range of non-ferrous and ferrous materials – including brass, bronze, aluminum, stainless steel, carbon steel and alloy steels.

Supported by 3-axis and multi-axis CNC platforms, we process everything from simple cylindrical bushings and spacers to complex rotational components with multi-step profiles. We also provide upfront DFM (Design for Manufacturability) optimization focused on turning feasibility – including stock allowance recommendations, tolerance optimization and feature accessibility review – to mitigate manufacturing risk and reduce total component cost.

Quality Assurance & Material Traceability

Every copper bushing is governed by our stringent quality management system. We maintain full material traceability with certified mill test reports for each raw material batch, conduct in-process dimensional inspection at all critical machining stages, and perform final dimensional verification, concentricity testing and surface finish measurement to ensure every part meets customer drawing specifications precisely and consistently.
