What are the typical applications for high-precision EDM machining?
Typical Applications for High-Precision EDM Machining
Aerospace Industry Applications
Turbine Components and Cooling Channels
EDM enables the machining of complex features such as cooling holes, venting grooves, and sharp-edged contours in turbine blades and vanes made from Inconel 718, Hastelloy X, and Haynes 230. With tolerances down to ±0.002 mm, EDM ensures aerodynamic precision and thermal stability under extreme operating conditions.
Lightweight Titanium Structures
Titanium parts like brackets, fasteners, and internal components fabricated from Ti-6Al-4V (Grade 5) benefit from EDM's non-contact process. This ensures distortion-free finishes for high-performance, weight-critical aerospace applications.
Medical Device Applications
Surgical Instruments and Implants
EDM is ideal for producing sharp, precise edges and fine features in surgical tools and implants made from Ti-6Al-4V ELI (Grade 23) and SUS316L. It enables fine detailing in orthopedic screws, dental drills, and bone-cutting tools, where sub-0.005 mm tolerances and Ra < 0.2 µm finishes are required.
Microfluidic Channels
Precision EDM is used in diagnostic and surgical fluid systems to create clean, burr-free microchannels in hard-to-machine alloys, maintaining smooth flow and minimizing contamination risk.
Mold and Die Making
Precision Tool Inserts
EDM is a standard for producing hardened tool steels such as Tool Steel H13, Tool Steel D2, and Tool Steel 1.2709. It allows the creation of complex cavities, tight radii, and mirror-finished surfaces for injection molds, stamping dies, and extrusion tooling.
Micro-EDM Applications
For micro-tooling, EDM is used to fabricate tiny features like ejector pin holes, narrow slots, and tiny ribs with extreme repeatability, unattainable by conventional machining.
Electronics and Optoelectronics
High-Fidelity Electrode Fabrication
EDM produces intricate electrodes from Copper C110 and CuCr1Zr used in semiconductor molds, high-voltage connectors, and cavity molds with optical-grade surfaces.
