Ultrafine EDM Graphite

Ultrafine-classified EDM-4 graphite is said to offer improved wear and surface finishes during finishing operations.

Ultrafine-classified EDM-4 graphite is said to offer improved wear and surface finishes during finishing operations. The graphite has a smaller grain size than the company’s EDM-3 version, which is said to result in more strength. The graphite is designed for close-tolerance medical, automotive, semiconductor and aerospace applications. According to the company, some users reported 10 to 15 percent improvements in wear on finishing electrodes, in addition to better surface finishes. The graphite electrodes are said to improve EDM performance when producing thin, deep slots and other critical features in mold cavities or parts. The company also offers EDM-1 and EDM-2 grades.
