Effect of Graphite Materials with Different Parameters on EDM

Release time: 2021-07-18



The higher the density of graphite, the higher the surface finish of the electrode it produces. For EDM, the loss rate increases with the graphite density. Therefore, choosing the appropriate density of graphite electrode material is very important for EDM processing.


2.Grain Size


The smaller the grain size of graphite, the higher the surface finish and the lower the loss rate.


3. Modulus of Elasticity  


The higher the elastic modulus of graphite, the lower the wear rate and the workpiece is relatively easier to be finely processed.
