Diamond dies uesd for drawing EDM brass wire
Standard galvanized wire: the core material is brass, zinc coating of 100%. Commonly used plating, coating thinner. The biggest feature is galvanized wire discharge performance and stability, cutting speed is comparable brass Siti high 10-30%, especially for more than four cutting precision machining. However, this electrode wire manufacturing process is most difficult to resolve the issue out of powder, only Germany and France, a few good quality manufacturers, such as Germany Berkenhoff company COBRA CUT A, MEGACUT A, German Heinrich Stamm's STAMMCUT ZC900 and ZC950, France Thermocompact company Thermo SWA, Germany buchem company bunol A, bunol TA and so on.diamond dies manufacturing factory from CHINA.
