The Strategy Of High Speed Machining Of Graphite Electrode

Graphite Electrode Manufacturer shares that graphite has high high temperature strength, low thermal expansion coefficient, good machinability and good thermal and electrical conductivity, so graphite electrode is widely used in metallurgy, electric furnace, edm and other fields. In the aspect of edm, the development of new graphite electrode materials and its machining technology has extended the application scope of edm and improved its performance.

Compared with copper electrode, graphite electrode has the advantages of small consumption of electrode, fast processing speed, good mechanical processing performance, high processing accuracy, small thermal deformation, light weight, easy surface treatment, high temperature resistance, high processing temperature, electrode adhesion and so on.

                                                    Graphite Electrode

Although graphite is a kind of very easy cutting material, but as a result of used for EDM electrode graphite materials must have sufficient strength to avoid damage in the process of operation and EDM machining, the electrode shape, thin wall and small rounded corners and sharp change) and also on the grain size and strength of graphite electrode put forward higher requirements, resulting in graphite in the process of machining workpiece easily broken, tool wear and tear. Therefore, how to prevent the workpiece from breaking, improve the surface processing quality and reduce the cost of cutting tools has become an important problem in graphite electrode processing.
