A non-traditional machining process that removes material using electrical discharges (sparks).
EDM employs a focused series of electrical discharges between an electrode and workpiece submerged in a dielectric fluid to erode conductive material through controlled sparking. This process is particularly beneficial for machining hard materials or complex geometries that are difficult to machine using traditional methods. EDM is commonly used for producing intricate mold and die components, where high precision and intricate details are required.
Producing a precision mold cavity in hardened tool steel with a dimensional tolerance of ±0.005 mm (±0.0002 inches).
EDM is commonly used in the tool and die industry for creating molds that demand high dimensional accuracy.
Machining delicate turbine blades with complex cooling passages from nickel-based superalloys.
This application is relevant in the aerospace industry, where EDM allows for the machining of hard alloys without inducing thermal stress.
