For example, the processing speed of graphite by milling is 2–3 times faster than that of other metals, and no additional manual treatment is needed, while the copper electrode needs manual grinding. Similarly, if graphite electrode manufacturers use high-speed graphite processing centers to manufacture electrodes, the speed will be faster ...

Roughing of graphite electrodes can be done by using inserts, if the electrode is large enough, or shank tools, if it is small. For electrode size 50x50 mm or above, we recommend using diamond coated round inserts RDHX0501 or RDHX0802 with a 13 mm cutting diameter and 12 mm shank diameter tool holder. Fig. 4 Fig. 4 shows an example of this tool.

Compared to graphite electrodes, copper is less efficient. It is difficult to machine or grind due to being soft and squashy. It is very difficult to de-burr. In fact, it is longer to de-burr than to manufacture. Graphite is the most widely-used electrode material. It was first introduced five decades ago.

By nature, synthetic graphite is electrically conductive and could create a myriad of problems if allowed to accumulate in areas that have a tendency to "short out" when in contact with foreign conductive materials. There are primarily two methods for controlling graphite dust during the electrode fabrication process.

Copy milling and form grinding. Preferred machining methods for the manufacture of electric Discharge Machining (EDM) electrodes are milling and high-speed milling, for-grinding and EDM-cutting. Since EDM fine-grained graphite grades still have a volume of open pores of 10 to 15 %, they can be impregnated with copper.
