Graphite - Wikipedia

Graphite (/ ˈ ɡ r æ f aɪ t /), archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure.It occurs naturally in this form and is the most stable form of carbon under standard conditions.Under high pressures and temperatures it converts to diamond.Graphite is used in pencils and lubricants.Graphite milling, the proper way - EDM Sales & Supplies, Inc.,Graphite milling, the proper way Shaiu-Wei Yin, IDI Precision Machinery Ltd.

Graphite is unforgiving of surface defects, reflecting even the smallest flaws quite clearly in the workpiece. As such, a good surface finish on the electrode before die sinking reduces bench time on the tool after. A fine step over, and small chordal deviation used to optimize surface finish give good results.
