The mechanical processing speed of Hp Graphite Electrode can be 2 to 5 times faster than copper. The discharge processing speed is 2 to 3 times faster than copper.
The material is less prone to deformation: the advantage is obvious in the processing of the thin rib electrode. Copper has a softening point of about 1000 degrees and is easily deformed by heat. The sublimation temperature of graphite is 3650 degrees. The coefficient of thermal expansion is only 1/30 of that of copper.
Antioxidant Graphite Electrode make electrodes that are faster, more efficient, and do not create dust problems. In these processes, selecting the right hardness tool and graphite can reduce the tool wear loss and copper breakage. If the milling time of the graphite electrode and the copper electrode is specifically compared, the graphite is 67% faster than the copper electrode. In the general case of electrical discharge machining, the processing using the graphite electrode is 58% faster than the copper electrode. As a result, the processing time is greatly reduced, and the manufacturing cost is also reduced.
