At Twin City EDM, our machining technology and processes have evolved alongside the American bio-medical sector since 1959. As medical devices have grown increasingly complex, and increasingly small / miniaturized in many cases, our shop has invested in new machines and CNC technologies to support the innovation that our customers bring to the table.
Medical devices and end products today demand some of the highest precision features and tightest tolerance control you’ll find in any industry, up to and including aerospace.
After all, some of these parts are destined for life-saving surgical instruments, high-tech diagnostic devices, or implantable technology. Tolerances measured in ten-thousandths of an inch, biocompatible materials, and strict regulatory traceability are all essentially the norm.
For medical OEMs and suppliers navigating today’s challenging supply chain landscape, reliable manufacturing partners capable of delivering both precision and flexibility are essential. That’s where Twin City EDM steps in as an invaluable partner. Combining advanced EDM and CNC capabilities under one roof, we support the innovation cycles that drive breakthroughs in patient care.
Precision Is Paramount in Biomedical Manufacturing
Biomedical instruments must function flawlessly in life-critical environments. A catheter component that fails during a procedure, an orthopedic implant with inconsistent geometry, or a surgical tool that doesn’t maintain edge integrity can compromise patient outcomes.
Precision extends far beyond the capability to hit a specified tolerance: it’s just as important to establish repeatability and reliable performance across production runs…which may sometimes be manufactured weeks, months, or even years apart.
Twin City EDM manufactures a wide range of components for surgical and diagnostic instruments, catheter assemblies, endoscopic tools, orthopedic hardware, vision system housings, and veterinary surgical kits. Each one of those applications demands tight tolerances, complex geometries, and materials ranging from titanium and cobalt-chrome to stainless steel and engineered polymers.
Our comprehensive machining processes are designed to handle micro-threaded pins, miniature connectors, and full device assemblies with equal precision.
Medical manufacturers work with us because we understand the stakes. Every part is held to the highest standards of quality, backed by ISO 13485:2016 certification for medical devices and ISO 9001:2015 for overall quality management. Traceable inspection data, cleanroom-ready production, and rigorous quality protocols support every project.
Versatile Machining Processes for Complex Medical Designs
Our customers’ medical devices typically feature intricate designs, some of which push the limits of conventional machining. Thin walls, deep cavities, fine threads, and tight radii are common requirements. Twin City EDM’s capabilities are built to handle these challenges through a combination of complementary processes.
- Our wire EDM services excel at cutting complex profiles and fine details in hardened materials without introducing mechanical stress. This process is ideal for surgical cutting edges, precision slots, and delicate features where burr-free finishes are critical.
- Our sinker EDM machine produces deep cavities, blind holes, and intricate three-dimensional shapes that would be difficult or impossible with traditional machining. It’s particularly valuable for mold components, custom housings, and features requiring exceptional surface finish. It is good for adding detailed features to medical components for the orthopedic kits for surgery.
- Swiss turning and conventional lathe turning delivers high-precision cylindrical parts with tight concentricity and surface finish control. Medical shafts, pins, connectors, miniature parts, and threaded components all significantly benefit from the stability and accuracy of our Swiss machining services. It is an essential for the manufacturing of medical components for devices that lead to production in the orthopedic or optical industry.
- Our 5-axis CNC milling services provide versatility for both medical prototyping and production, enabling rapid iteration on complex geometries, along with repeatable manufacturing of the end product. Multi-axis milling supports undercuts, angled features, and intricate pocketing required in many medical assemblies.
- Micro hole popping (small hole EDM drilling) creates precise holes as small as 0.008 inches in diameter through hardened materials, essential for fluid pathways, ventilation, and mounting features in miniature medical devices.
- Integrated laser welding services and laser marking allow for end-to-end fabrication of high-precision medical devices in-house at Twin City EDM.
By housing these capabilities in-house, Twin City EDM eliminates the delays and communication gaps associated with outsourcing to multiple contract manufacturers. Fewer handoffs mean tighter process control, faster lead times, and greater accountability. When design changes occur, as they frequently do in medical R&D, we can respond quickly without delay and without sacrificing quality.
