To complete this stamped copper conductor ring with tabs for the power generation industry, we had to employ multi-directional forming techniques: we used a variety of machining processes including blanking, piercing for the 12 holes, forming to bend 12 tabs to 90 degrees and pre-form ends to 20-30 degrees, and more forming using a Mandrel to complete the 360-degree shape. All of this was done on punch presses with universal tooling. We used 0.625 half-hard temper copper sheets for the material’s superior electrical conductivity.
The finished product measured 6.693” in diameter x 0.945” in height x 0.062” thickness and weighed 7.0 oz. We were able to drill the holes with tolerances of ±0.005” thanks to our precise CNC controls, meeting the specifications in the customer-supplied CAD designs. In total, we produced 250 pieces and were able to deliver to our client in the Midwest in just four weeks. The pieces were subject to a thorough dimensional and visual inspection before shipment.
