Custom Copper CNC Machining

FlexiTurn provides custom CNC machining and sheet metal fabrication services for high-conductivity copper electrical components — including U-shaped brackets, bent contact springs, connection plates and terminal bars. Manufactured from 100% IACS grade pure copper with burr-free edges and tight positional accuracy, these parts serve critical power distribution and signal connection systems. We support the full production workflow from precision blanking and CNC drilling to optional electroplating, delivering production-ready parts directly from your engineering drawings.

• Precision CNC Drilling & Contour Milling: High‑speed 3‑axis CNC machining with solid carbide tooling delivers accurate mounting hole layouts and fine feature contours, maintaining tight positional accuracy without inducing residual stress deformation.
• Controlled Form Bending: Automated press brake bending with calibrated tooling compensates for springback in pure copper and brass alloys, ensuring repeatable bend angles and consistent geometric profiles across production batches.
• Controlled Burr Management: Calibrated high‑shear blanking and secondary deburring workflows keep edge burrs within defined acceptance limits, eliminating sharp edges and reducing contact interface irregularities.
• Functional Plating & Anti‑Oxidation: Surface finishing options include electroplated tin (Sn), silver (Ag) and nickel (Ni) per ASTM and ISO standards, tailored to application requirements for oxidation resistance, wear performance or low contact resistance.

Precision Processing & Surface Finishing Capabilities

Core Fabrication Workflows: Deploying 3-axis CNC milling for prototype part blanking, CNC drilling for accurate hole features, and sheet metal processes for bending and forming complex profiles.

Post-Processing Options: Comprehensive surface treatments including electroplating (tin, nickel, silver plating for anti-oxidation and low contact resistance) alongside metal deburring & polishing to eliminate sharp edges.

Optimized Process Parameters: Fine-tuned machining parameters tailored to copper material properties to prevent tool wear, material deformation, and surface scratching during manufacturing.

Material Capabilities & Quality Assurance

Broad Material Portfolio: Beyond ETP pure copper (C11000), custom CNC machining support covers brass, copper alloys, aluminum, stainless steel, carbon steel, alloy steels, and engineering plastics.

Full-Cycle DFM Support: Early engineering guidance at the design stage, offering technical advice on hole layout, bending radii, and stock allowance to reduce production risk and optimize component cost.

Rigorous Quality Control: In-process dimensional inspection, final verification, and complete material traceability to guarantee every copper component matches drawing specifications consistently.
