Comparison parameters | Advantages |
Production Speed | The price of isostatic graphite is about 25% compared with the same volume copper electrode's |
Machining accuracy | The machining speed is 3-5 times faster than copper electrode's, the machined surface is smooth. Electric discharge pcocessing speed is 1/3-2times faster than the copper electrode's, it is better for Rough Machining |
Weight | The density of graphite is only 1/5 of copper's, it is more suitable in the production for larger electrodes |
Loss | Used as EDM electrode, which cosumption is only 1/3-1/5 of copper electrode's, the coating of spark decomposition of carbide compensates electrode loss |
High temperature resistance | The melting point of graphite is up to 3650ºC, no deformation under high temperature and more suitable for machining bone electrode |
Electrode Cohesiveness | Stick damaged graphite to save time and reduce material costs |
