Diamond Coating vs DLC for Graphite Machining: Which Coating Is Better for Graphite End Mills?
During a recent project machining high-density graphite electrodes, we ran into a familiar shop-floor challenge. Using identical tool specifications and cutting parameters, some graphite end mills cut dozens of parts effortlessly. Others suffered rapid edge dulling after just a few passes, compromising the entire run. Our root-cause failure analysis showed that cutting parameters were not […]
