EDM surface quality describes the surface finish achieved during wire electrical discharge machining. It is a key quality factor in wire EDM, especially for precision components, tools, molds and applications requiring high contour accuracy.
The achievable surface depends on several factors, including the wire electrode, coating, workpiece material, generator strategy, main cut, trim cuts and machine parameters. A suitable EDM wire can help achieve fine surfaces reproducibly while maintaining process stability.
bedra offers different EDM wire solutions for this purpose, ranging from proven precision wires to new coating technologies such as blac technology.
For users, EDM surface quality is closely linked to productivity, process reliability and component requirements.
