a new technique for the fabrication of graphite edm

Waterjet vs. EDM

Although parts cost more to produce on an EDM than on a waterjet, because it's so much slower, an EDM actually costs roughly the same to buy as a waterjet and less to run. Price tags on new wire EDMs start as low as $90,000 and can exceed $500,000, depending on their accuracy ratings and the amount of automation on them.
