Electrical discharge machine Daegun technology constructs wire-cut edm technology facilities in order to produce about 100 of wire-cut edm annually, and secures specialty and skills for stable and precision for producing high-precision and deposition wire-cut edm. The high-precision and deposition wire-cut edm is a special tool machine is good at not only precision section processing such as punch, die, up and down different shape, taper, reiteration, but also high-precision processing such as innovative improvement of external roughness. The wire-cut edm business part at daeguen technology is able to manufacture all parts of edm ourselves as assembly, control box assembly, wiring, and wire harness.
