Why Machining Is the Most Important Process Step for Graphite Electrodes & Pins. Most performance issues for EAF Electrodes are related to the joint. Eighty percent (80%) of Graphite Electrode product failures as well as higher consumption rates are related to machining. Machining is the most important item for joint performance. Getting one or two more heats per electrode is what separates the Tier 1 from the Tier 2 suppliers InnoGraf is a USA company delivering high-quality UHP graphite electrodes, Graph Check ™ laser measurement, precision electrode machining and additional services to the steel industry. InnoGraf specializes in the production of electric arc furnace (EAF) UHP graphite electrodes for steel and other ferrous and non-ferrous metal production.
