How do these new graphites machine?
Simply put, Micron Research EDM graphites machine great! There are three key physical properties which impact the machinability of graphite. These are strength, hardness and density. Because of the double bonding engineered into all Micron Research graphites, higher strengths and lower relative hardness have been achieved, resulting in a very machinable family of EDM electrode materials. In fact, Micron Research materials are not only easy to machine by conventional methods, but the higher density E-900, E-940 and E-970 materials also WIRE EDM exceptionally well. Often overlooked, but very important, is the effect density has on machining. Greater density in EDM graphites generally result in finer achievable detail and smoother surface finish. When working with denser materials, like the MICRON E-970, machiners may want to consider slower feed rates upon entry and exit when milling, and higher spindle speeds are always desirable when machining graphite. It stands to reason that the mor
