Why Do Graphite End Mills Wear Quickly? Understanding Tool Life and Improving Machining Performance
In precision graphite machining, a familiar pattern often frustrates machinists. A brand-new graphite end mill performs smoothly at first. Then, after several hours—or just dozens of cycles—the surface finish deteriorates, dimensions begin to drift, and micro-chipping appears on the cutting edge. Strangely, different machine shops running the same grade of graphite with identical cutting tools
