How Diamond Coating Thickness Affects Graphite End Mill Tool Life
During a graphite electrode machining project, a client faced an unexpected tool life issue. Using the same batch of diamond-coated graphite end mills on identical graphite grades and CNC machines, tool wear varied wildly. Some cutters ran smoothly for hours, while others suffered rapid edge chipping, spiked cutting forces, and poor surface finishes. Failure analysis […]
