Twin City EDM and Manufacturing continually invests in technology equipment that allows us to efficiently and effectively fabricate intricate and complex components. With a reputation for executing part features previously thought to be unattainable, we were contracted by a customer in the beverage industry to provide a solution for drilling micro holes in the tool shown here. Used to form beverage cans at a high rate of speed, this punch nose was fabricated from tough M2 tool steel hardened at RC 62-64.

Our CNC micro hole EDMs, equipped with automatic electrode feeders, feature the ability to locate parts within very exacting tolerances. We programmed the equipment to pop multiple holes at 55 degrees around a circular pattern through this very hard material while leaving an immaculate, burr-free hole. Dimensional and visual inspections ensured that we met the tight ± .002″ tolerance requirements. We do blanket orders shipping 150 units monthly for this customer.
