Consumable benefits: many would argue that the EDM process is only as good as the consumables it uses. Steed Webzell asks those in the know to explain just why that is the case

摘要

It would seem that the days of ' manufacturers viewing EDM consumables and wear parts as little more than commodity purchases have passed. Today, the correct selection of graphite, copper electrodes, oil, dielectric, wire, resin, carbide contacts, guides, nozzles and filters can have a significant effect on quality, machining performance and productivity. Opting to deploy inferior quality EDM consumables is a risk that EDM shops can ill-afford to take in an age when the pressures facing all manufacturers to improve part accuracy and surface finish, drive down costs and reduce lead-times, ensure that every aspect of production needs to be continually assessed. Intech EDM, part of the Agie Charmilles GF Group, has developed a market reputation for the quality, reliability and cost-competitiveness of its OEM spare and wear parts, and EDM consumables.
