Premium Cut EDM Wire — Brass & Specifications

Wire cut EDM (also called Wire EDM or WEDM) is a precision machining process where a thin electrically charged wire — typically brass — cuts through conductive metals using controlled electrical discharges. It is widely used in mold and die making, aerospace, and automotive manufacturing for intricate, burr-free cuts with tight tolerances.

Wire EDM can cut workpieces ranging from less than 1mm up to 300mm or more in height, depending on the machine and wire type. Advanced multi-technology EDM machines can handle a wide range of material thicknesses, making them suitable for both micro machining and heavy mold and die applications.

The most common EDM wire types include standard brass wire, coated (diffusion-annealed) wire for higher cutting speeds, and fine wires for micro EDM applications. Wire diameter typically ranges from 0.07mm to 0.33mm. WSM Technology supplies wire compatible with Mitsubishi EDM machines and other major EDM equipment brands.

EDM consumables including wire, filters, and resin tanks are often machine-specific. WSM Technology's CPG Department offers consumables compatible with Mitsubishi EDM machines as well as a range of other EDM equipment. Always verify wire diameter, filter sizing, and resin tank specifications with your local WSM representative before ordering.

Filter and resin replacement intervals depend on machine usage, material being cut, and water quality. As a general guideline, filters should be replaced when pressure drops or cutting performance declines, and resin should be changed when conductivity rises beyond acceptable levels. Your WSM Technology specialist can advise optimal maintenance schedules.

Yes. WSM Technology supplies consumables for Wire EDM, Sinker EDM, and Micro EDM machines. Their CPG Department through the Encore Group provides filters, resin tanks, and compatible wire for multiple EDM technologies, supporting shops across Northern Ohio, Western Pennsylvania, and West Virginia with local availability.
