Grain Size Effect on Graphite Machining: How Graphite Microstructure Affects Machinability
We recently consulted for a client manufacturing precision graphite electrodes. They used the same CNC setup and cutting tools to machine two graphite grades with identical nominal hardness. The results were night and day: the first material machined cleanly with predictable wear, while the second triggered severe edge chipping, heavy dust generation, and accelerated cutting […]
